Engine flush - good or bad?
In this video we look at engine oil flushes and why they are unnecessary with today's modern cars. Throughout the entire process we'll take a listen to the sound the engine is making, along with taking samples through a coffee filter to catch any contaminates.

you should open up the valve cover after adding the engine flush to physically inspect the cleaning effectiveness of the flush inside the engine.
Yeah sure, because it takes a second to do so...
@@rafars2246 honestly does not take that long
@@andretsang7337 it's a bitch on a 2008 Altima 😂
I waited for this sad
@@andretsang7337 try that on a tsi ea888 1.8 tsi or 2.0 tsi.....u r in for some serious long hours
Watched the whole thing waiting for a second look inside. I want my 13 minutes back!!
Yeah sorry Ken, a follow up video was always planned but a big kangaroo had other plans. It jumped straight into the side of the car just in front of the drivers door (lucky for me), and twisted everything so much that the bonnet wouldn't open. I did a lot of other work to that bucket of crap, took a lot longer than 13 minutes.
@@Sawickipedia OK. I guess that's reason enough ;-) Around here, if I head up country a bit the worry is moose!! Glad you're OK. It's too bad though, other videos on the subject sometimes compare the oil before and after but not an actual view inside the engine. So close!!
@@Sawickipedia you can still check the engine oil 😉
also spent 13 minutes waiting for a look of theclean engine - it shoul have looked like this: czcams.com/video/x4u64lKBbhQ/video.html
Wow, what a turn of luck for that wee car!
Glad your ok!
great effort...and great video too...thnak you
Thin oil is all the rave. So is ring failure. As my engines age, I increase viscosity. No smoke or oil usage with 3000 mile changes. Syn oil is very clean. Gas cleaner keeps gas blowby to a minimum. No prob unless 0w20 oil is used. 5w30 is my minimum now! 10w40 in my older v8 and generators in summer. 10w30 winter small engines syn blend works fine. I go 50/50 syn, syn blend these days in older gens that state conv oil only. Yes they are old, like 4000 hours! Lol. Works for me with 100 hour oil changes max!
A lot quieter....LOL!!!! LOVE IT!!!!
Would have been good to see under the cover after the flush 🤔
I agree.
That what made me watch to the end
That’s the hole point of the video 🤷🏼♂️
What’s a hole point?

Didn't explain nothing 😀 in a 13 min video...wtf
Thank you, you've saved my 13min kkkk
I have never ever had a problem with the flushing of oil I well recommend it the new oil will stay clean for at least 500 miles
can you flush a 2011 diesel engine ?
@@rajZ772 I don't know mate but I say get your oil changed regularly what car is it
@@mohammadayub2760 Its a toyota etios GD diesel. 148000kms driven, and the exhaust pipe is smelling like vinegar. Also the engine is vibrating more. I have also ordered the moly diesel purge to put it in the fuel tank. And thinking about the engine flush. Whats your take?
You should try it on old engines so we can clearly decide.
Think it is interesting Shell Helix is considered cheap oil cause it is a great oil
Yeah, I was thinking "who has Helix as their just-lying-around oil?!" :)
The point is to possibly free up stuck piston rings.
For tappety noise engines flush your engine with diesel add one
Litre to existing engine oil start engine until temperature starts to
Rise repeat this 4 times over a
Full day then drain oil and filter
Empty old oil from old filter yes replace old filter all bungs and fill
Rocker cover pure diesel engine cold
Till starts to warm this will clear all ports drain again remove old filter 2nd time and bin mew filter replace
Oil bung and top up new oil to recommended level and your little
Engine will be like new nice quiet
Smooth you will be proud of your
Little self
I bought a brand new Dodge Dakota and I received coupons for 12 oil changes. First time I hit 3000 miles, I went to the dealership to get my oil changed. The asshole mechanic recommended an engine oil flush with a vehicle with barely 3K miles. The cost was $800. I said no. He kept pushing it. He wouldn't take no for an answer. I just said "give me my keys" and left. I gave away the truck after over 200K miles. I assumed that the mechanic didn't want to honor the free oil change. That dealership went out of business.
Nothing is free
Holy shit! 15w40 is heavy duty diesel oil here in the states!. For our cars we use 5w30 or 5w20
what is the correlation between engine sound with oil cleaning?
The oil pick up has a screen and tiny particles will pass the main filter...
The purpose of the oil flush is to thin out the particles so it will pass through the screen then filtered by the oil filter...
nope, flush is dessigned to clean the internals to keep the new oil fresh more time without contaminate itself. Nothing more.
Nice to see you running that engine for rather a long time with the door closed lol did ya feel abit funny at the end of the video hahahah
Really? I don't remember, wonder why 🤔😄
@@Sawickipedia have you ever treated your car to this treatment again.. and was there anything different after few weeks buddy
A follow up was always planned but unfortunately I hit a kangaroo and it got written off.
👍 Nice. But What a pity, The Sound level must be measured with db's level. At least from application in phone, its free.
And next episode perhaps we can see what's inside engine cover look like.
Thanks.
I would clean it with synthetic at short intervals...never a engine flush
Sometimes its so bad and the car is old. That it's worth the try.... $10 try on a car that's most likely gonna need a full rebuild isn't a bad idea tk see if it gets you another 30-60k miles
When you do oil flushes one thing iam quiet sure is that it won't just drop of chunks (a using a pick) , it's a process of dissolving my 2 cent
Okay, you flushed the oil on a clean engine. Why didn't you open up the valve cover so we could see the results?
I found its good I flush every other oil change I have no problem with all of my trucks and equipment I've have had great results I use oil and kerosene mixture and let the engines idle for about 20 mins
Am I the only one who has noticed your car logo saying Turd instead of Ford? XD
You are the first to comment on it 😅
I miss that turd
Am i the only one who noticed this guy looks like Conor McGregor🤔😅
Liqui moly engine flush is the best out there
How do you know?
Just used it, yes, it is; neutral on gaskets and seals, and safe on cats
Добавьте 250 мл Oil Flush на 4 литра старого моторного масла. Дайте двигателю поработать 60 минут при 1500 об/мин. Периодически увеличивайте обороты до 3500 об/мин. Слейте старое масло, залейте новое масло и замените масляный фильтр.
Did you do the follow up video?
I engine flush all my vehicles Its called regular oil and filter change
Interesting car, single cam 4 valve per cylinder ?
How much the engine speed during flush process?
Glad I decided to read some of the comments before I watched the entire video, I saved 10 minutes of my life😄😕
is this car still working fine?
That motor was clean before starting. Yellow it's ok. Oil is supposed to stain. Bad is if it's black and build up then you can test the difference.
Do an oil change with cheap oil and a cheap oil filter dive a few 100kms then flush if it's the first time you are doing it in a older car that way you are not overloading the oil with with crap.
Flush engine with clean oil 3x with new filter. Drain, new filter and oil , then cleaner
Run the engine. Then inspect engine, oil and filter. I have done this before. Solvent cleaners with no detergent additives are designed to remove money from your pocket.
Can't afford to get a oil pump change. So im going to try the flush. I pray it works.
Have you done the flush as yet. My PCV seems to be blocked. As I've only just found out about the glove test. And it blew it up. So my predicament now is do I use it . And if i use it. will it cause an oil leak.
how is it after the prayer? did the flush work out?
it did in my case: czcams.com/video/x4u64lKBbhQ/video.html
i think engine flush goals to clean deposit inside the engine, not see oil.difference.
nop..i rather do short interval oil change out.. some sludge is better to be there as a sealant and naturally being a gasket. I experience some cars need to do top overhaul after doing flush.
Engine OIl has everything the best for car. Engine flush is only for abandoned car with tons of sludge because sludge is worse than just leaking rubber gasket from the flush
Like your video. I have a hybrid and I disagree that you do not need to flush if you do regular oil changes. I use 10000 mile semisynthetic oil and premium filter, change every 3000 and it still burns oil and creates lot of sludge. Hybrid toyota oil scraper piston rings block very easily and oil sludge begins. Other modern toyota engines have that problem too, like RAV4.
Your engine should work more efficiently now.
I agree 👍
Wow you use semi synthetic and you get sludge, who would of thought.
"premium oil filter" but semisintetic oil... Dude, learn the basics, you are doing it wrong.... And it burns oil because your shity oil cant handdle the high temperatures and the TBN scks... It creates lots of sludge because it doesnt have any detergents or are minimum. And because you don´t flush the engine, when you put a new oil inmediatly contaminates itself.... Go to the mechanic school and learn the basics please.
@@TimberWulfIsHerebetter yet semi-synthetic on a hybrid. Yuck.
That is considered heavy engine varnish with signs of sludge formation (black spots). Its a sliding scale from silver -> gold (varnish) -> dark gold (heavy varnish) -> black (sludge)
I have an 04 Honda Civic w/135k miles and underneath its valve covers it looks almost brand new. Lot of engines are neglected and people assume gold is good, gold is OK on a high mileage engine, not great but OK and not a deal breaker. If i saw that on a engine with less than 100k miles i would avoid it, that is a sign its been ran into the ground.
When’s the next video coming out????
Valve cover check after flush???
i would do an oil drain for the old one inside the car ( keep filter ) , put cheap oil and add engine flush, keep idle for 15 min., drain oil and change filter with new oil......i think this will clean all the old oil in the lines inside the engine and remove any residues !! and i think removing the pan and wash it before the new oil will be something optional but better too to make sure of everything
@mohamed UAE a cheap mineral oil for 15 min. isn't a thing wouldn't cost you much and you shouldn't do it every time you change oil,
do it after 3 changes maybe
Not a good idea. Putting in a flush can loosen up pieces of solid material. If you leave in the old filter, the material can bypass the filter and block up an oil passage. That's why I say, unless you have an extremely severe case, just accelerate the oil change interval. It ran before you flushed it. Right?
@mohamed UAE I have to put 5W30 oil in my engine (FAP equipped) which is very expensive, can I do a flush with a cheap oil 10w40 for example. Thx
Unless it's BG which is a several step process costing more than $200, that's if you can find it? Wouldn't try it if there wasn't anything to lose, except for money. That being said follow the manufactures recommendations.
I was just thinkin as u have cover open if sprayin wd40 and after adding oil to flush it out if wd 40 will help to clean tje engine or crc
Why u didn't open engine cover after flush
czcams.com/video/x4u64lKBbhQ/video.html
you are welcome :)
I’ve got a 2004 GMC Sierra I just put a used motor in. Old motor blew up. New motor runs great but oil psi high. Should I flush it?
I would. Especially if you haven't opened the new engine's oil pan or valve cover. I would clean the oil pan just in case you have too much sludge.
Where is second part?
Did it work or not??
i got a motorcycle 30k km odo, should i engine flush it or just go to a mechanic and do a top overhaul just to clean carbon deposit?
Just change the oil in time, no need for any other faff.
Cheaper too in the long run.
Should it flush in every service time..
No, after the 4 time you service your car
should probably open the garage doors before you guys do this at home
So what if you have a spun bearing? You need to get metal particles out of engine so flushing the engine sounds like a good idea.
If u have spun bearings and metal particles in the engine bye bye engine
Nice video but are you sure 15w40 is right oil ? I was more expecting right specs semi 10w40.... can keep your engine bit cleaner, without flushing ?
In this case 15w40 was the best option given the engine age (250,000km). 10w40 would normally be the recommended weight for this engine and climate. And yes IMHO a decent semi or full synthetic oil will always extend the life of your engine far more than a oil flush which I personally don't recommend for any engine
Good answer I'm with you.
I did once flush old diesel engine mercedes 190d, idling 10 min and engine start knocking... suspect hydro valves, so don't think is good for all kind of engines.
But I like keep engine clean and I do change oil 5w30 on my 2.0 tdi every 5-6 k miles hoping make engine good life.
Nice video thank you.
@@aleshudek5323 Yes I do the same on my Mazda MPS 5w30. Definitely need to do regular short interval changes on a turbo direct injection engine
@@Sawickipedia I don't get it, that doesn't make any sense. Putting 15 instead of 10 will only delay the lubrication on the critical parts on a cold start. Later the oil will act as a 40.
I just bought an old low mileage car. (2009 with 42000km), I think the oil is from 2015 and the previous owner rarely drive it since. I'm going to change oil ,but should I flush it?
Certainly change it asap, but I wouldn't flush it. If you are really concerned dump the current oil and run some cheap same weight oil through it for 10 minutes in between
Add half a quart of ATF with that cheap oil. Drive around 50-100 miles. Then change oil and filter.
@@z31rider24 yep, did exactly that. I'm gonna use the other half bottle to flush it again on my next oil change, just to be safe :D
Nice thing about ATF is that it cleans @ a slowe rate. Unlike engine flushes; which do a great job at cleaning but they too strong. You will clean out too much gunk and deposits too soon. You run the risk of clogging up screen/filter. The last thing you want is oil not getting to where it needs to go because something clogged it.
I'll leave a link how to clean/flush with all ATF.

Lots of talking but no engine show at end.... Focus on experiment instead of lecture.
LOL comment of the decade!
@@binagarten4667 Car was wrecked after hitting a kangaroo, that's why no follow up. Kangaroo's can kill !
Every new car I've had for the past 20 years has had the old engine oil flushed before adding new oil. All dealers do it, so it should be fine as long as the car you're using has always been flushed. Don't try to flush the oil on a 200k km car that's never had a flush however.
why ?
Fuck it
@@GCP81 like an other youtuber said, cause it can remove buildup, that are actualy avoid leaks.
do what you feel
...that engine might have looked clean to you because there's no obvious sludge. But what you are looking at is varnish. The valve train including the springs, is simply coated with the stuff that was caused by oil breakdown when it went too long without a change. It's not as bad as sludge, but it is a sign of infrequent changes, the true cause of engine damage in this engine, if any. Since this video lacks a satisfactory ending we may never know.
It's not a real science on this scenario, older ,high mileage engines tend to be owned by people with limited finances, you recommend this and it doesn't work the customer will be wondering why you spent 'their money on parts and labour ,interaction with the customer is the most important way to do it I wouldn't do this with a new customer, only customers I've dealt with for many years,saying so,some cars come back to me after 40.000 kms,having been looked after by another mechanic, it's like playing with dice to mate some people happy,still learning after 44 years.
Nah, also professionals use this products from different brands, it actually helps with older car mainly when people "forgot" their oil changes.
Damn buddy literally cursed the poor ford, said "if it lasts that long" like 50 times and it ended up not lasting that long
I have water in my engine oil I was recommended to do an engine oil flush. But lots of people are saying not so what do I do?
That's probably a head gasket or a crack in the block or head. You can try a sealer product. It might work. I have no idea what engine, the mileage or what the typical problems of that engine are.
@@anonymike8280 I checked them and it wasn’t it but I appreciate the help. It’s a 1988 crx 128K miles. I did see water in the engine oil though
@@xXMomia75Xx It has to come from somewhere. In fact, it has to be from the water jacket. If it is water you are seeing. How do you know there is water in the oil?
@@xXMomia75Xx Hey! This was getting good! Answer his question 🙏
Mate no Followup video on your Channel with an Update? 👁👁
I disagree with you in regards to your point about the the flushing product
The 10 minutes is actually for those who use it regularly but for first time you should have left it for 30 minutes specially if the car milage is high like the one you applied your testing on it
Always a good idea to stray from manufacturer’s instruction and play Russian roulette with your engine
It's a great idea and I have kept an engine alive with flushing. Also using transmission fluid in the oil before I change it helps when the engine is burning oil. The rings are dirty. Thus these treatment work. Oh BTW way beyond 230K miles and it is still running! Oil consumption has been under control the oil was Not Syn but Regular motor oil changed every 3,333 miles. Totally disagree
Flush when needed. It is bath for the engine. Or just quit taking baths...... LOL
No part two???
try this one:
czcams.com/video/x4u64lKBbhQ/video.html
different car, diifferent engine - but hey - who cares
Its just liquid hydrocarbons so basically fuel.
Its clean because it doesnt have EGR
What the hell! Should've pulled the valve cover again!! What's the point of looking before but not after?
Yeah sorry, it was always part of the plan to make a follow up video showing after shots. Unfortunately a kangaroo had other ideas and I never got a chance to have another look
@@Sawickipedia Haha, oh damn!!! Well I guess we’ll never know..
I might do one myself. Seems like there’s loads of engine flush videos on here but none with an actual before and after look inside the engine.
what will happen if the flush little bit left on the engine because it's not properly drain. what will happen with the car / engine?
Maybe oil gonna lose viscocity...just my opinion...i prefer flush with oil change 2000 km and put again fresh oil
Where is the inside look like??????????????
what u are doing ? starting , u open the engine , after that , u dont show . and the full temp & engine oil different are from the quality of engine oil . try using 0W 20 Total , u will find ur car a lot quiet
the reason he did not remove the crank case after the flush is it is like ERG cleaners they dont work or if they do there is no differance.
the safest way is to do a oil and filter change run in for about 20 miles at 3000 -3500 rpm let it cool to about 40c do oil and filter again that will do the same job.
i do this 3 times i use cheap oil and filter for this but on the last i use good oil and filter at least you will not blow a seal doing this and it will if you are doing on a diesil force regen of your DPF
my 14 year old 308 1.6hdi has done 75k and the engin is as clean as a new car
I never asume I just do it
Add 250 ml of Oil Flush to 4 liters of old engine oil. Let the engine run for 60 minutes at 1500 rpm. Periodically increase the speed to 3500 rpm. Drain the old oil, fill in the new oil and replace the oil filter.
I remember this from Forte motor flush
My avalanche sounds like a sewing machine so I guess I really don't need a flush do I?
As expected, happy the oil flush did nothing. Change the oil regularly is best method to maintain an engine. The use case where it might be beneficial to flush the oil, I don't want that car has a good chance to kill it anyway.
"so all and all it looks quiet clean" mate it's burnt af, don't do an oil change every 50k xD yuck
Put a cheap cleaner, cheap oil and then we light the car on fire 🔥 to see what happens..
so, how can you judge if the flushing works or not if you try it in a already clean engine????? dont make sense bro!
Engine flushes are not needed. And on high miles cars it can open up a can of worms and cost you big $$$$.
engine flush are mainly for older vehicles and equipment not newer vehicles that's the difference
15-40?? 😮are you living in Iraq? or saudi arabia? .crazy 😂just crazy.
Please!! 13minutes to make that conclusion? Don't waste your time.
I do it regularly.flush it
Risk taker. Lol..🚗🧨 do this on junk clunker..
What is the point of this video if u barely seeing what he's doing...smh
Flush is good, period.
Poor video
LMAO your "cheap oil" was very good expensive oil. If you can get more of the Shell stuff and its cheap, I would stock up. Some oils here in the UK can be £70 for 4L.
