Clear Engine Oil - How Many Oil Changes Does it Take? (with Color Comparison)

- As an experiment I wanted to see how many oil changes it would take to have clear oil come out of the engine. There is no real use for this test because this oil will become dirty within hours of driving due to engine blow-by and oil consumption.

I made a clear oil filter our of glass, check it out: czcams.com/video/bvmT7UCWA2Y/video.html
drop the plug in the pan , so funny
The teenager working at Valvoline thought I was crazy for bringing the car back from yesterday's oil change but I remained insistent I needed to make sure I got all the acetone out from my accidental engine flush - I probably sprayed a couple ounces of CRC throttle body clean right into the camshaft from the PVC hose intake connected to the air box. So then I added Lucas - after I had driven a bit without the Lucas. So then I got the oil change yesterday - added some more Lucas. My silicone shaft seals started leaking but they were leaking a couple years ago from using MMO in the crankcase. So I think it's just since the oil is so thin. So the seals still leaked with the LUCAS in but not as much. But then my mileage was terrible and I discovered the Lucas totally clogs up VVT engines. Luckily I didn't put in that much. Maybe 8 ounces at a time - twice. So then I returned back to the 2nd oil change - explaining how I had to MAKE SURE I got all the acetone out of the oil as the acetone eats up the seals. So as I drove home I reset the MPG average and it had jumped UP a mile at least! I could not believe it - I was getting over one mile better than the factory rating for the MPG and this car has 267K on it. hahah. Thanks for the advice on insisting on multiple oil changes in a row.
I miss those times when CZcams videos was like this, simple, straight to the point, no BS. Now, CZcamsrs stretch a single video with so much unecessary BS just to get ad money.
That's true
I remember some will film a whole vlog/go on a shopping trip before finishing the video. Once I found out how content creators get paid, then I realized why some will make 30 minute video on changing oil.
Clear, real, quick and up to the point 👌
Something I have wondered too! Thanks for keeping it to the point. Great video.
Glad you enjoyed it!
I dreamed about it, you did it. thanks man :)
Appreciate the last bit about it being an experiment haha as i was thinking this would not be feasible for the average person to do on the regular, looks expensive with all that new oil and new filters used
Very well done. Thanks for posting this.
Glad you enjoyed it!
Owen, thank you for going to the effort to do this experiment and share it here. This is super interesting. I think it should be particularly informative to those who let the motor oil drain for an extended period, even overnight, in hopes of getting the cleanest oil after oil change. To me, your experiment shows that extended drains are in vain, unless they combined it with multiple changes.
Thank you for the compliment. I actually did a 12 hour long oil drain video that you might be interested in: czcams.com/video/4U39Nudyj0s/video.html Basically draining when hot for 1 hour is the sweet spot.
Cool experiment 👍
Instead of actually using an engine flush additive, it's best to do two to three subsequent oil changes like this do a thorough clean without having to have the additive ruin the seals.
Nice presentation. Love it! :-)
Thank you kindly!
Thank you for sharing, I always wondered, now I know
Wow lesson learned!
Wow! Interesting! I always wondered how many would it take or if it had any impact if it's clean or just with 1 change. You should have done it in more detail, like Temps, or more stuff like that with an program or an machine that takes in consideration all that. Idk if ODBC does it. Anyway, I've seen with Liqui Molly it lives your oil at lvl 3/4 with flush it once. Would be interesting to see how clean or how many times does it take to be completely clean if you use Molly like 2/3 times. I know it's an expensive process such as the one you showed.
Really apreciate the time! Awesome work! Definitely goona sub!
Glad you enjoyed it and Thank You for subbing!
LM Engine Flush, Amsoil EF, and 505CRO are all excellent, high quality products.
Use dino oil and a cheap filter for a week. Let it run nice and hot. Then drain and replace the filter and oil with a good one.
99% removed.
I really appreciate your work thanks alot 👌
Thank you very much!
great video, thank you!
Glad you liked it!
I'd like to see how long it took for that last oil to get dirty again.
great video!!
Thank you!
You should have done an engine flush after the 6th to see if it becomes dark again.
I was tempted to do that since but I needed super clear oil for the purpose of my glass oil filter video: czcams.com/video/bvmT7UCWA2Y/video.html It would be easier to see how clean oil flows in a glass filter rather than dirty oil.
@@OwenLucas
As you witnessed, it turns dark fast.
Did a similar procedure about 27 years ago with a used car I just bought. We also added a chemical flush to the original oil and each one after. Can’t recall exactly how many we did but enough that the last drain came out clean. I do remember the first 3 at least came out very dark.
This was a GM 2.8 liter v6. Changed the oil every 5,000km after that at home with a Chem flush every time, car ran great until it rusted apart. Did have to swap out the transmission, should have done a few drain and fills on the transmission as well.
So you say the car is still with you and working like new?
i did it differently, when the first time the oil drained finished, i used compressed air to blow the rest out. I had to use a big hole as to create a huge air current. It worked but made stuff messy
Thanks for the video! Did you end up swapping to the new oil filter every time or used the same one for all your subsequent changes?
I used a new oil filter each time to avoid cross contamination.
Three changes got the job done. Subsequent changes had mostly a cosmetic effect. Going extended interval makes the oil extra dirty. It is best to change more frequently with cheaper but still properly specked oil. Oil companies say you can go extended with their product but will not tell you you'll need an extra flush afterwards ($$). Imagine the damage to new oil if after an extended run with fancy oil a normal mineral oil is used afterwards! It will be junk from the start. It is best not to do these super extended drain intervals. 10k is ridiculous. One should probably not go past 5k especially if the car is older and has some blow-by past the rings or runs rich, contaminates oil with fuel. Thanks for the video, awfully wasteful in oil but very illustrative. Subscribed.
Thank you Sir! I agree, 5k is the right mileage especially for older engines.
Nice. Glad you went through that… but oil viscosity is more important than color.
Great point!
Great video, decided to sub. I would love to see a second engine flush maybe on the 4th or 5th attempt just too see how much extra dirt it would bring out. I know that would probably cost a lot just be curious how many times you could repeat this process till the engine looks completely new. I'm about to do my very first oil change myself on my bmw 320d and will definitely do a double flush. But if I had more funds I'd do what you've just done in the video. Every used marvel mystery oil? Can be used as a light engine flush, or oil treatment and fuel treatment. Seen amazing things with this product.
Thank you Joseph! I have heard great things about Marvel. I think you will have a lot of benefit with flushing a diesel especially if you have a lot of miles on it. I have a few videos coming up addressing your questions so stay tuned!
I've done this, multiple clean oil flushes, then a chemical flush. No difference, no additional removal, even oil analysis showed little increase in particulates. On a 15 year old engine, 170k miles.
@@OwenLucas
I have used MMO in the crankcase for many years with success, as it is a very gentle cleaner. Project Farm further confirmed its cold start and wear protection properties for me.
But I would not recommend it for the fuel tank on modern cars with catalytic convertors. It contains sulfur. My cat had to be replaced right after using this stuff in the fuel.☹
Nice. 3 was the magic number, IMO. I need to do that to my new to me car. Took the valve cover off, and it looked cruddy. Lack of oil changes, obviously. But it has 280k miles, so, ya know. Could be worse 😆 Nice vid 👌🏻
Congratulations on the new car! This video was basically a test on how to get the oil clear. I would do a flush first as shown in my engine flush video: czcams.com/video/rCo6aCed0bo/video.html
@Owen Lucas Thanks! That video is what led me to this one in the first place! Was a very interesting video also.
I was thinking about using a chemical like you used in that video, but like I said, my car has about 280K miles... It doesn't seem to be leaking/burning oil now that I've changed the valve cover gaskets. I'm a little concerned about using strong chemicals in such a high mileage motor that I'm also pretty sure has been neglected on oil changes and standard maintenance for at least the previous 5 years. Previous owner bragged about how he'd driven it 5 years and 100k miles and only charged the alternator in that time. I've seen nothing that leads to me believe he did anything to the car that wasn't keeping it from running. He took "If it ain't broke, don't fix it" to heart with that car 😂
So, I'm just thinking of doing what you did in this video. I'm sure it won't do quite the job the chemicals do as far as cleaning. But it also won't potentially over clean things that I might not want over cleaned 😆
Might change the oil 3 times like you did, and then put a bottle of some light engine cleaner. Something that stays in for like 1k miles slowly cleaning. GG
I always come back to this video after change my oil to gaslight myself that my oil is that clear inside the engine
😂
Super...........
Interesting, we use to run diesle fuel through the engin on the old VWs too clean them out.
you can try diesel ci-4 instead of synthetic gasoline engine oil for the repetitive flushing and see the difference. i've tried once
Great vid, now I'm interested how the oil will come out after driving it til next oil change
Thank you for watching, I am curious as well, 5000 miles to go!
@@OwenLucas 5k miles is how many months?
I have a 2002 Tacoma with 300 k miles and the previous owner must have taken fairly good care of the engine because I have changed the oil twice since I have had it and my oil is perty clean it’s got color and is not black by no means.
Change oil every 3000 miles ( this used to be common, and still is with mechanics ) with synthetic oil and there will be no dirt build up and 500,000 mile engine life with a new Japanese engine.
would love to see this done after using liquimolli engine clean
Now did it come out clearer next oil change ?
Can you please tell us does this effect a positive performance on the car??
My mechanic did not tighten the oil cap after service so there was leaking he subsequently had to drain the new oil out and put more new in I found the car ran a lot better
I haven't noticed any difference in driving, but starting does seem quieter with the fresh oil compared to the 8000 mile oil, especially since it is below freezing here in the mornings. If some of your engine oil leaked out from the mechanic not closing the cap then it's possible it ran worse because of a lower oil level. I had a friend who's engine burned so much oil, by the time they changed it less than 2 quarts came out and it looked like tar. New oil, to the full level, made a huge difference!
Can we see how this support the other video using Moly that it's the oil doing the cleaning, not the Moly, unless severly gunked up. Nice pouring, you're getting good.
Ha, thank you for the compliment, you are not the first to mention it! I have an upcoming video doing the exact thing you mention, so stay tuned!
I once came over a comment saying when you flush with cheap oil either u add it max level like usual oil or add it half then run 10 mins then drain and again add the other half then run 10 mins and then drain again before adding the usual engine oil.
I would always fill up to max level, if you go lower than the lowest allowed mark on the dipstick, that could be bad for your engine.
Can you do 2 flushes with fresh oil and original filter and then new one once you’ve done the last flush ?
Add Liqui Moly to old oil, run for 10 minutes. Drain, add new oil and replace filter. Run engine for 10 minutes, drain, replace oil and filter. Good to go, no need to flush again at this point.
Do you have to start engine each time you pour a new engine oil to flush in this video. Thanks for the video but just curios to know the exact process beacuse i'd like to do this tomorrow. thank you
Yes I started and ran the engine for about 10 minutes or so. To be honest this was an experiment, no need or benefit to do it in a vehicle. An engine flush with Liqui Moly would do a more thorough job.
Also would it help to rev up the engine whilennthe engine flush is in the tank? Or just let it idle?
The instructions with Liqui Moly state not to rev the engine, just idle it. The oil is thinned from the flush chemicals so lubrication is reduced slightly, so adding a load onto the crankshaft could cause more wear on the bearings.
After how many km or months do you recommend changing oil?
It depends on your vehicle, driving style, and time between oil changes. Most modern engines can go to 5000 miles but you are fine with 3000 if under heavy duty use.
@@OwenLucas So mate my Audi had the same VW oil for 2.5 years and 22,000km. I only ride motorways & 95% with cruise control. In April 2022 I changed the oil with a high quality full synthetic oil and re-changed it after 3000km. Do you think this was a good way to clean the engine?
@@jerryx2000 An engine flush is a good way to clean an engine, especially if you have higher mileage. I would say almost any engine can use a flush after 160,000km on the odometer. 95% motorways is not so hard on the oil, but that is quite high km. Then again if you were using a high quality oil to begin with, you are probably fine. What really breaks down oil are high temps from towing and idling like in a construction vehicle or taxi. I've read that 1 hour of idling is like 30 miles of driving. I have a video about engine flushing here: czcams.com/video/rCo6aCed0bo/video.html
I used to think I was changing my oil correctly all these years until I assisted a fellow pilot change the oil in a Cessna piston single airplane. He also in the past built high power race engines.
He fully drained the oil until it barely dripped. Then with the drain plug still removed he poured new oil in and observed what was coming out. He kept slowly pouring in until the oil flowed clear out the drain. Then he installed the drain plug and put proper amount of oil in.
I wonder if this technique might have saved one complete change using your criteria? Any thoughts? Thank you.
That's a very interesting technique, literally flushing the engine. I agree, it probably could have saved an oil change. My logic to running the engine was to circulate and warm up the new oil to capture as much of the old oil as possible. The first oil drain is very black because it has 8400 miles on it, even though I was using Mobil 1 High Mileage Extended Performance, I decided to change the oil early for my next video....and as you will see, very clean oil is required.....stay tuned! Thank you for sharing!
I kind of did something like that by accident. I forgot to put back the drain plug and wasted around half a litre of oil. 😆 After putting back the plug and filling it up, the oil has become very clear in the dip stick.
By the way, I used STP engine flush before and this was the final third engine oil refilling.
That's a really good idea. I'll probably start doing that with spare oil I have laying around.
Hi Owen, do you have to buy 6 bottles of oils to accomplish this experiment? If yes, how many Litres for each bottle are you using?
I bought six 5 liter jugs of oil, and used about 4 liters out of each one. I had a lot of left over oil including the usewd oil of which the last 4 drains I reused since it was in great shape.
💞💞💞
my car cranked almost 130 k odo kms. i always afraid of engine flush ,as it may damage the engine . can i try with liqui moly
Of course, I shouldn't cause any damage. The engineers at Liqui Moly know what they are doing 👍.
I never go pass 5k before I change my oil.
For a cheap oil filter the super tech filters are better than the cheap frams. Good stuff though thanks
Great point!
This was probably good to do anyway because you guaranteed the majority of any liquid moly that absorbed into any deposits or were left coating anything were out after the second cheap Mobil 1 non extended change you did after draining the flush+oil.
PS, any Blackstone analysis for this?
No sorry, not this one.
@@OwenLucas that's okay. The gimmick is overrated and they always say "you can go longer" like that one sentence is worth buying the TBN. Changing synthetic at 6k is sufficient and I'm pretty sure at 7500+ is just fine. Sludgy is what I'm more looking at. That's why new oil will always start faster.
Next time I'm going cheaper and doing the $20 Napa one.
i can see that the color is changed.,, but may I ask how about the performance? is it the same?
No difference in performance.
@@OwenLucas thank you for your reply sir
I wonder how it runs, doing the same
To my Coyote
dark oil doesn't mean it has gone bad , in fact , all motor oil will turn dark within few hundred miles of driving , just keep on top of your OCI then you are good to go , especaily with a Toyota engine , nothing will go wrong.
Sage advice. 💪
How about a double LiquiMoly flush?
My engine has been flushed so much I don't think it would show anything at this point. 🤣
Is this the car you did the liqui moly? Thinking of doing a flush and refill on an 200k mi. used car
Yes this is the same vehicle, though the flush was performed a few thousand miles before this video already. I drained the oil multiple times so that I would have clear oil for my glass oil filter video: czcams.com/video/bvmT7UCWA2Y/video.html
Then open the engine
Could you post the oil test results?
I have a video up soon, stay tuned!
@@OwenLucas sounds good. Month has passed but will look for it
Any update after 9 months?
So in the end you are just stuck with as much cheap oil in your engine, then there was black oil leftover after the first flush? The engine always keeps some and is never fully empty, interesting..
And I wonder if it is recommended to do an oil flush with chemicals added every other maintenance period, or is a simple flush just enough?
These flushes were just for test purposes only, there is no benefit to multiple flushes.
Regarding a chemical flush, depending on your conditions, vehicle age, and maintenance, I’d say a flush every 50-100k miles is fine.
5 oil changes, and using the cheapest oil and 5 lots of oil filters here in the UK would cost £250 about $300.
I saved the last 4 oil drains, back into the bottle. A 5 quart ( .94L) jug of economy oil can be purchased for $22 with an economy filter for about $4. at Walmart. Supertech is their store brand. Walmart is the most economical retail chain in the US.
Cant we use cheaper grade oil for this kind of testing instead oem recommended grade?
If the weight is the same you will be fine, you will only be using it for a short period of time. 👍
@@OwenLucas great, thanks for clarifying my doubt.
My 1.9 tdi chage oil every 60-70.000 km and it's 100 times more perfect than any new engine that change oil every 10000 km.....
The drain for oil changes #4 and #5 looked pretty much identical to me...? #6 was barely any cleaner.
Yes it does to me as well. It seems like 4 oil changes is all it takes to get the dirty oil completely out of this engine.
@@OwenLucas exponential reduction
I'm gonna need about 130€ for cheap 5 4litre oil, 5 cheap oil filters and an engine flush additive, without the final good oil and oil filter..
This was just an experiment. There is no need for anyone to change their oil 6 times in a row. If your engine is high mileage and has some age, engine flush and 2 oil changes should be enough. I explain this in my engine flush video: czcams.com/video/rCo6aCed0bo/video.html
Ok... off to get some more oil and filters then to quench my ocd.
I would rather do this rather than having to pour engine flush in my engine. This is undoubtedly a waste of time and money but 100% safe on your engine.
You can even bottle up and reuse the last 2 or 3 oil changes.
despite expensive method but i think this method brings better result than flush, no?
I did the same but with 7 days apart for 2 times and in my 3rd attempt it became totally clear.
i was going to do this but, i would be spending money, maybe ill just replace engine every 3k miles from now on
now give me the oil used for flushing
Nearly impossible with a diesel
Should Should Should fill oilf filter eith oil and rim the gasket with oil
No need to fill the oil filter
Modern cars don't need this anymore.
Please Help, Nissan Trying To Charge Me $1800 For An Oil Flush. It For A 2016 Nissan Maxima That Rattling Under The Engine And Sometimes Smoke Out Of Tailpipe.

I don't see how an $1800 oil flush will prevent a $12,000 engine replacement. I recommend getting a second opinion from another mechanic.
@@OwenLucas Thanks For Responding.

I imagine this video was quite expensive to make
I used Walmart Super Tech Oil, one of the cheapest synthetics on the market. Economy Fram filters as well. Thank you for watching!
Maybe around $140 more or less.
@@OwenLucas you could use the flushed oil and filters after, at least for shorter OCI’s
@@OwenLucas
Excellent oil. Used conventional ST for the flush, then returned to ST synthetic. I did the same with cheap ("pump & dump") Fram filters.😂
My high mileage kia gets a double change every other oil change 😅
So minimum 4x
It depends on your age, mileage and how much sludge you have. In my older 180k mile engine 4x made it look pretty good 6x was basically clear.
If funny but 3k miles oil chNGE WILL jave the sME RESults.
I hope you reused all that oil after.
Yes, the last 3 or 4 drains IIRC. They were like new anyway.
My god, so much oil was wasted.
I saved the last 4 oil changes for re-use, perfectly fine oil.
Should have used a fumoto drain valve for all these drains 😅 I have one on each of my cars us open the valve and drain
I'll have to look into those, would have been much easier to drain!
I don't believe in those things. In most oil pans those drain plugs sit above the bottom of the pan, therefore the pan doesn't fully drain so you are diluting fresh oil with your old contaminated oil. If you are lazy, I guess it's better than not changing your oil at all, but not as good as fully draining the oil old school.
@@budlanctot3060 I am away from a lazy type buddy... I just learned how to work smarter than harder through my 18 years of cars ownership....the drain valve has a short thread so it doesn't go up to much in the pan to make a higher drain exit....I change oil frequently more than anyone so... Old residue mixing up with new oil is not a biggie, although it happens in any type of motor if let a car to drain for hours there will always be old oil at thr top and bottom and in the pump... The valve is very high flow it drains fast... And scooty kilmer a very well known mechanic.. You can search him talking about the valve too....when unbolt the plug it makes a hole for the oil to escape and when you turn the valve open it makes the same hole for oil to escape with a little less diameter... It will take little longer but same process
@@mohamednawwar1450 if you're listening to "Snotty", our modern P.T. Barnum, you're beyond help. He's a click-bait charlatan, which makes you an idiot for following him. 18yrs of car ownership makes you an authority? Well, then my 56yrs of ownership makes me 3x more experienced. I reiterate, in most cases those quick drain gizmos are for lazy people, and trying to rationalize it means you're compromising fact for convenience. That's your choice, but don't try to convince weaker minded readers of your fallacy.
i not gonna waste 25 litres of oil in one go i just cant afford it,,,,,, i mean your idea is good you must have cash to spare to buy 50 litres of oil not me 😁
This was just an experiment, I do not recommend anyone do this. There is no advantage from changing oil 6 times other than having a clean crankcase which i needed to do for this video: "The Correct Way to Flush Your Engine - Leaves No Residue" czcams.com/video/rCo6aCed0bo/video.html
Can all videos be like this and not be about how your great grandfather. 🥴
at the 2nd time I would just use the same oil and just run the car for 10 mins then drain it out do it 2 more time using the same oil , then the fifth time I just put the new oil in. I think people should done it at 100k, and 200k miles.
You’re telling me you wasted 20 gallons to flush your engine?
20 quarts....with some of the cheapest Walmart oil available.
@@OwenLucashow often do you do the flush?
@@lilpullout just that one time
Oil is recycled.
Seems rather wasteful but I can see for the sake of science.
Change the oil every 4000 or you will be sorry. And mad
...8K on ANY MOTOR OIL is absurd and sacrificial to say the least.....
