please do a review on BlueDevil
Scotty Im cleaning my metal gas tank because its very rusted inside . Do you recommend to paint the inside of the tank?so it doesnt rust out again and if you do what paint should i used?
Scotty Kilmer my v6 bmw car gets bad mileage and its like new, i also used cruise control but i didn’t do a difference.
I put Gibson headers and free flow exhaust on my GMC pickup truck 4.3L. I picked up 5 miles to a gallon. I think part of it was the old Catalytic converts were clogged up and a bolt busted off the manafold due to back pressure. With the new headers and free flow exhaust I got lots of power and better gas mileage? is that is normal? If all vehicles can pickup 5 mpg it is a good investment to put headers/free flow exhaust system.
Beemers a Bummer
1- buy a good car
2- sell it for toyota celica
3- change oil every 1500 miles
4- repeat 60-120 years later
Duuuuuuuhhhhh.......
😂😂😂😂😂😂
LoL
1500 miles is WAY TOO EARLY. That's insane.
Proper air pressure in the tires is huge in getting optimum gas mileage.
And make sure to have the wheel tracking checked from time to time, a 'crabbing' car will eat up gas.
Really? I'll test that out
Is 6000psi tire presure good enough?
@@denniero6904 close! Just a little more
@@denniero6904 just keep going till you hear a loud boom
I've seen very few ppl on youtube who actually know cars like Scotty. And I love his goofy energy!
Regular maintenance is the key to anything lasting a long time. I work in a manufacturing plant where our jobs depend on regular maintenance to succeed in our market. Downtime cost a whole lot more than regular maintenance does with cars as well as anything else that moves.Thanks Scotty.
Tire pressure affects efficiency as well
a lot more than the air filter in my experience
and it also affects stopping distance too. Affects tire wear too. Multiple reasons to keep the tires inflated properly.
S yes but he did mention the air filter which can get dirty fairly quickly, especially if u drive on dirt roads. And also many people don’t check their tire pressure very often.
effect
I think checking your tire pressure every now and then is something everyone should know, it's even the first think you learn in driving school.
Learn the art of COASTING! So many people are on the gas 100 yds before a stop, ridiculous!
So much this, but it doesn't work in the city. Not only I've gotten 1 liter more per 100kms but I noticed I don't even use the brakes that much anymore. I used to change them ever 2-3 years and last I looked the pads still had 2/3 life left.
Yeah you're right. Although in traffic this doesn't work, unless of course it's a steep road downwards for example.. My daily commute road is mainly highways but with some traffic (and full stops sometimes), my car now does 17 mpg - but with the A/C on. It's terrible for my salary though :'(
@teel6060 I try to coast with the car in gear. I heard somewhere that when the car is pushing the engine the computer shuts off the fuel injection.
I really want to thank you for all.of your car tips. I watch them all of the time and I've really learned a lot about how to repair my cars.
Thanks again,
Trey
Scotty, dude, do you ever drive your car? In all the videos it has 239,000 miles lol
Paris He said in another video he doesn't go out as much
that's just his BS car to make people think he's poor. he has a Maybach in the garage in the back.
chieftp actual rich people drive cheap cars
zhbvenkhoReload is that what you tell yourself to feel better about being poor?
my great uncle drives caddis, benzes and tahoes. and he's rich beeeeeeeeeeeeyatch
5:45 There's the cat!
What's the Wi-Fi password? It's "Kitty-kitty-cat. Kitty-kitty-kitty-cat." Project Fi
Google project fi
Scotty should feature his cat sometime.
Moar of Scotty Cat!
''Here's my 2014 cat I bought, I named her Celica Toyota Kilmer. She gets good PPS (Pet per Smile-age) and has been a very reliable cat. So If you have cat problems and it isn't purring right, you got to pet her abit more! Or buy a good quality cat!''
Scotty, you are a man of true progress ! Lots love from Greece. Hope God protect you at all times.
Scotty, I always love watching and learning from your videos. I love the pop up pictures you add in! Some of them are hilarious and I think will attract or keep younger viewers watching!
As I said in another Scotty video - I have preached this for 40 years! But most of the time it falls on deaf ears! When the car breaks down most owners do not want to hear what they did wrong or what they could have done to prevent it! They only want to know 3 things - "Can you make it go?" , "How much? , and "How long?"
Shepperd November just say the truth if they don’t listen don’t stress about it !
And that's why they've been designing vehicles and lubricants to require less and less maintenance. Change your oil once a year, transmission fluid in five years, and no one even knows what a lube job is anymore. With EVs, people will hardly need to do any maintenance ever.
some of the cars I hear on the road sound so bad, god knows what they did to that car or probably didn't even look after it at all
and if they only realized that if they spent a little on preventive maintenance, they could save themselves LOADS of money on unnecessary premature repairs. It's really just simple stuff too, fluids and getting to know the sounds your car typically makes. If it makes a weird sound, find out what it is and get it fixed or fix it yourself. Chain reaction, right? The leg bone's connected to the hip bone kinda thing. Many things affect something else connected to them.
Bill Does Stuff Forget it! You're tilting at windmills! I do airport transportation and my car is my living! I'm one of those crazy people that still changes oil every 3000 Miles, transmission fluid every 15000 miles (even more important because most cars do not have serviceable transmission filters) coolant every year, spark plugs and serpentine belt every 50,000 miles, wax every month (because my car has to look good for my job!). And I do all of the servicing MYSELF! In addition I have three other cars to look after. My 1999 Hyundai Accent has 172,000 miles on it with the original engine, clutch, and transmission! My 2000 Chevrolet S10 was purchased 7 years ago for $500 with 74274 miles on it and a DESTROYED ENGINE! The previous owner knew NOTHING about maintenance! So go ahead, claim your family time cuts in to your auto maintenance and some guy like me will come along and buy your destroyed car and fix it up or worse yet it will die a premature death and end up in the crusher! Either way, you'll be in PERPETUAL car payments!
Make a compilation of you mentioning how many miles your celica has.
Golden Grenadier Better yet, create a timeline of exactly how many years it's been at 239k. I cannot think of a video of his showing something different.
David Regan yeah. In the last 3 months it looks like he put 4 miles on the car unless he made the videos at the same time. Then since a video from almost 8 months ago he's seemed to have put 17 miles on it. And that was when he was still using his old intro.
my 2003 has almost 300k...mechanic needs lunch, well he has to do a test drive anyway so their personal cars never get used unless they drive to the bar
David Regan Yeah I've been wondering about that too.
he just loves his car . i own a 2002 land cruiser with 300000 miles on it . original drivetrain and brag about it all the time because i love it and i am proud of it
You’re right on the dot for this one Scotty. I can attest to this myself with my 2006 BMW 325iA. It’s amazing how people don’t realize too changing fluids makes a significant difference. But one reason too is that people might also have to change their driving style. I changed mine and averaged 36mpg Highway from Charlotte, NC to Fredericksburg, VA in a car rated at 29mpg highway, and this was fully loaded as I was moving back from Houston (Willowbrook Area).
My best return though was the sensors. I always say between 85k to 100k is the time to change the MAF and O2 sensors near the cats. Plus around that mileage they’re just about worn out anyway, so some preventative maintenance can also help prevent any possible future damage to your catalytic converters.
You saved me with my Jeep before.i love your content man . Your voice and presence is awesome. You should get into entertainment lol
Scotty I think we all want to see a video called “everything I DISLIKE about my Toyota celica. I’m genuinely interested!
MrClassicDoctorWho I reckon that would be a brief video. Lol
I agree but I’d still be interested haha maybe it has really inconvenient cup holders or just terrible floor mats. I need answers
Buy the right car in Scottys mind; A Toyota celica, camry or corolla that's between 10 until 25 years old with no rust and costs below $1000.
Or a Honda Civic
Ilias Lamari I don't see what's wrong with them
I have a 34 years old corolla that mean its no good? But to compensate, I have a 16 years old Civic. Is that good?
Ilias Lamari just buy the car of your dreams and hope it don’t cause you nightmares in the future!
Ilias Lamari shhhhee 😶
I dig your videos. Straightforward, informative, and honest. Thanks for being here. Have you ever thought about being an automotive shop instructor?
I'm kinda surprised you didn't mention oxygen sensors. If I'm thinking correctly, a weak oxygen sensor can affect gas mileage.
True but a bad oxygen sensor would give bad fuel trim readings so you’re knocking 2 birds with one stone by checking the fuel trims.
Is that MAF sensor ?
what is fuel trims
@@maffra7686 basically, how much the computer is adjusting the AFR (Air Fuel Ratio).
I have a 02 Buick le sabré with 300000 and it’s running sharp I do regular maintenance very happy with it.
have a 97 GTP S/C. Love it.
I HAVE 98 LESAbre 110000 runs great
Anyone who thinks that Buick LeSabres aren't terrific cars is nuts. They last forever if you maintain them well. It's incredible how many of them are still on the road. Mine's a 1996, and every single time I drive in any of the cities in my area, I will encounter LeSabres all over the place. It's not unusual for me to be in a parking lot, or stopped at a red light, and be surrounded by three or four LeSabres, all in excellent condition and running well. Every mechanic I've ever been to has told me never to sell my car, because it's one of the best used cars out there.
Surprising
Omg you have the most useful car information I've ever seen. Thanks Scotty
Glad to see your channel blowing up with subscribers. Love most of your advice.
Thank you, Scotty. I really needed this video for my car!!!
I love Scotty's energy, never a dull moment!
Great advise; great cat 5:41 🐈 You make it look easy to cram that much information into 6 minutes! Thank you for sharing your knowledge with us!

Men that love cats are great guys!!!😼✔
If you listen at 1.5 x speed, then he's crammed even more info into only 4 minutes 😂
Perfect timing Scotty! I was just saying how my car seems to use up more gas and this video comes along. Thank you!!!🙂
Dear Scotty! I think you are awesome! I tell all my friends about you. I am so happy for your success and that your an old school guy who loves what he does, loves to work and loves to help people. I wish you a ton of subscribers and likes! God bless you!!! B
2nd, Hey Scotty how u been? I was around ur way back in May in Houston for a navy reunion with my friends, Houston is a nice city man and looking forward to coming back before the end of the year is over
hello and glad to hear it!
Excellent sound advice, from a Master.
Thank you Scotty-
Scotty is right.
I’m very diligent about preventative maintenance. Probably more than I need actually. My feeling are that a little spent on the front end actually saves much more on the back end. Every repair I do is back to spec.
Had a transmission expert tell me that he would be almost out of business if people would just follow the maintenance schedule.
Thank you so much Scotty for making this video..
You are a shining star in this universe, may your happy wishes comes true for you and your dear family..
Simon from Chicago
Hello @Scotty, I am your fan in Guatemala... I am always learning from you and you are a great benchmark for me when fixing my car or taking it to mechanics.. glad you are helping us with such amazing videos. I run a 1998 honda CRV with 248k miles on it, still pretty strong :)
Fantastic tips from the master Scotty!
Ozzstar he is the Master!! 👍
Scotty awesome video. I have no idea about car troubleshooting or repairs. . I had a Nissan California 1988 or 89 Philippine issue. I had a mechanic/friend back in the late 1990’s in Manila tried to figure out where the water was coming from soaking my floor carpet wet when it rains hard. We kept stripping my car floor carpet and side door panels off but it never got better. Helping my friend work on my car before taught me a little bit. Anyways, there’s not so major mechanical problems on my car except for that and the idling. Seeing your vids and your untiring effort giving your viewers a bunch of ideas on how to take care of your own car is really delightful. I want to learn more of how to troubleshoot and take care of my own car. I saw a couple of your vids a month or so back and now I’m a new subscriber. More power to you and your channel from Illinois.
5:45. Scotty's kitty uses the walkway instead of walking on the gravel. Smart kitty!
Great video! It's all about maintenance.
Scotty, you couldn't have uploaded this at a more better time. This is EXACTLY what I needed. Thank you.
So, you also drive with the foot on the brake?
principetanguero I thought left foot braking helps the lap time
Helps the lap time if you are in a circuit of competition. in the streets or highway is not necessary to abuse the motor or clutch
principetanguero
Not unless you're Fred Flintstone 😁
YaBA-DaBA-DOOOOOOOOOOO
Sweet Video Scotty. Thanks for the hard work!
Scotty great video.
I noticed once after repacking my front wheel bearing with some very expensive grease that I regained 2 of the 3 mpg I had lost with that vehicle over time.
Another tip: you don’t have to drive like a maniac, hard acceleration, stepping on the brakes, speeding etc. Drive conservatively
Oh, maybe that explains it. Damn.
damn, are you sure though? I floor the accelerator pedal in my old Toyota and do 180kph+ everyday. Could that really be the reason for my bad mileage? I think think the real reason for my poor gas mileage is due to fueling up on normal gas instead of premium gas. Yep, that's definitely the reason.
Nope. Wrong. Maniac is the way to go. 😀
Driving conservatively is fine as long as you're not in the left lane in the way of this maniac! 🤣
or, or, you can drive like a granny, oh wait, somebody already said it.
When i first got my truck it was getting 14mpg city. Changed the fuel filter and it went back up to a normal 17mpg city. Haha thing was clogged to the max.
Thanks a bunch for the very useful video!! I do go along with the fact that buying the right car and maintaining it very well & successfully mitigate the risk of declining gas mileage. As well, driving very carefully does help out with gas mileage (besides preventing auto accidents and traffic violation claims for sure).
Man you got 3 hundred thousand new subs fast once you hit a million! Good for you Scotty! You deserve it!
Great vid Scotty. Ile be watching this a few times to memorize it all.
Live Life good idea. I should watch this a few times and act!
Jody Hakala I dont see why not 👍
People who drive with one foot on the gas and one foot on the brake drive me CRAZY. I know a guy who has needed THREE THOUSAND dollars’ worth of brake repairs in less than three years. And, you guessed it; he drives with one foot on the gas and one on the brake. Can you hear me screaming in pain through the computer? Whoever taught him to drive like that at his driving school should be arrested for murdering his brakes!
Unless you are in a narrow residential area with allot of kids you shouldn't have your foot anywhere near the brakes while accelerating.
1notgilty in Mexico everybody drives with one foot on gas and one foot on brake.everybody drives standard but the way
My grandma drove like that the only person I know who drove with 2 feet and getting in the car with her was a death wish.
Sammy Hagar method
I use one foot for the gas and one for the brake but never do I put my left food and rest it on the brake while I'm driving unless I'm stopped at a stop light.
Man, I love this channel. Anytime I need to do some work on a vehicle, I come here first. Better than Google!
Dude I learn so much from you!!! Thank you so much for the channel...!
Dont forget the EGR valve and O2 sensors. O2 sensors in my experience usually go out shortly after 100k miles no matter how good of a car it is. Those are 2 semi cheap and easy fixes Iv done on a few cars.
Can 02 sensors be bad before they trigger an engine light, or ??
@@graybenyo6735 definitely
Another excellent video!👍🏽🇺🇸🇯🇲
I love your sign about the garage door at the beginning of you video!!!! Mercia!!!!!
Love how your glasses fog up at 1:45 and you notice and laugh a little, hee hee, lol! 😄😆👍 your great scotty!
i love this guy, so genuine
You forgot to mention tires and alignment
lasegundaenmienda gmail that’s true tires
Allignment doesent matter
@@BmwMe-uh9sy alignment does. Your car will have more resistance without it.
Hey Scotty, every time i watch new video you put smile on my face to know more and more about cars
Love these scotty. Your just like my garage dude 😃
Old day Toyotas were gold. Original injectors still running. Thats why I still love my 1991 Toyota starlet Hatchback.
Lots of love and best wishes Mr. Kilmer.
Very true I have 1997 Toyota starlet with 60 thousand miles and still runs like a Swiss watch 😜👍🇦🇺
That Toyota Matrix in the video was made with General Motors side by side with the Corolla
Scotty The Zeus of mechanics
Great advice Scotty, thanks!!
Hey, Thank you for taking your time and resources to save me money, God Bless!
Hi Scotty. Great advice as always.
What are your thoughts on injector cleaners in the form of fuel additives?
Viren vs
Think he has a video on this. Look for fuel/gas additives video with Scotty Kilmer.
I never heard "bad gas mileage" so often in a video 😂
you always rock mr.kilmer you waste no time and inform us well without boring , while the rest do exactly the opposite ,,much respect from SUDAN
Scotty's video's teach so well. He is always very through. Great stuff.
Love your video's, Obama drop the mic for Scotty lol
The guy driving with his left foot on the brake pedal at all times is lying about "driving school taught him that". NO WAY. ALL DRIVING CLASSES TEACH YOU TO USE ONLY 1 FOOT, YOUR RIGHT FOOT, TO OPERATE ANY CAR WITH AN AUTOMATIC TRANSMISSION. They even teach you why NOT to "use both feet".
Great video, again, Scotty! Nice cat too!
Great info, thanks!
Spark plugs!!!! My 2014 silverado 2500hd was running rough. My mechanic said new spark plugs and i thought spark plugs dont fix anything!! Well i read in the manual that 97k should be changed i got 92k. Changed plugs and air filter and brand new!!! Turns out ac delco plugs good for 100k. Truck is brand new and getting 16 hwy and 12 pulling trailers again!! Luv it
Run some Mmo or b12 chemtool through it on occassion.
I'm pretty sure 02 sensors have the biggest impact on fuel economy as well as tire pressure and how the driver drives the vehicle
Never knew that cars get bad gas mileage as they age - I guess that is because I always have taken care of every car I have owned. Learned something today, thanks Scotty.
Great, simple info!
Scotty .. The cat is your wingman or an employee?
Scotty Kilmer, please upload video car malaysia Proton Saga. Plz bro
Thank you for all your support and I love the channel.
Stumbled and found this site by accident. I suscribed. I've got a 10 year old Chrysler convertible. It's been a good car. The problem has been the 3 accidents. People love to hit it. Driver door replaced. Trunk area redone twice. Teagards...
There is alot of mechanics in the comments with 40 plus years of experience. good job CZcams
What if the exhaust is as bad as yours?
Thank you Scotty, your a life saver! 😃👍
Super good vid. Thanks.
scottie-best car guy guide
I thought it had to do with the poor ethanol fuel mixture.
Great video!!!
I was watching and start to smile at 5:45 for your helper showing off ;)
Here's another tip: Don't ride on the passing lane and keep right except to pass. It may not affect the left lane hog, but it affects others around them that want to pass, which brings down the overall lane efficiency and gas mileage for those other drivers. Not only that, they're creating a dangerous situation where road rage and accidents are imminent.
Hey scotty, what's your opinion on fuel additives to clean injectors? Like fuel injector cleaner? I think it's like a 700ml bottle you add to a full tank
Lucas deep clean efi cleaner. The Best
Redex. Watch the top gear CZcams put 6mpg back on a car after 1 use
I love watching your videos. Once I’ve watched them, I make my kids watch them and then I quiz them over what they just watched.
Thanks for the tips Scotty! 👍 Btw, that is some cool cat. 😎🐱
Can you say Quadrajet? Look at the secondaries on that carb.....750cfm?
King Miura that was a computer controlled quadrajet they are made on 800 cfm bodies with a limiter on the secondaries.
that BMW guy hahahahahah
To make matters worse, John from honestjohn uk also recommends people to drive automatic cars like that. :(
He must have been trolling hard. Never heard or seen anyone drive with their foot on the brake all the time.
Vitamin B it's called left foot braking. A race driving technique that's largely useless on the street.
@@MChronicleSword constantly having your foot on the brake is a technique? Does it have a name by any chance? Perhaps, the "drive like a mentally challenged" technique?
Vitamin B sure, if you want to call it that. I did say it's useless on the street
Totally worth sharing! Thanks!
Nice video, thank you for sharing it.
Scotty “common sense” Kilmer is my fav imaginary uncle
My cars gets worse gas mileage cause my foot goes to the floor alot love to feel the v8 power lol
Michael Trower Ford sucks
Bmw M3 e46 bmw fanboy
Bmw M3 e46 bmw = bring mama's wallet your parents bought that for you didn't they troll
Even if I wasnt a BMW fanboy I'd still say Ford is trash, their even using plastic on important engine parts like BMW so they are really shady. I never trust American cars at least the Germans make quality engines that are durable unlike your typical Chevy, Ford gm
Yes Michael trower. I had same problem so got a straight 6 instead. My bmw 740i was nice but you needed a mortgage for fuel in the end. gas in England is dear!
Thanks Scotty. Love the video. I have a question : How you manage to include the black and white cat in every video? Cheers!
Holy crap that is sweet! I didn't know they existed. I may have to pick one of these up! Thanks Scotty! 😀
Another little trick I’ve learned to better mileage and I know people will say I’m crazy. Stick to one fuel brand. I had my 2014 Wrangler between 23-28 mpg and they’re only supposed to get 18-20. That’s with larger more aggressive tires.
It takes about two or three months to notice a difference but give it a try. It’s well worth it.
Fuel brand has nothing to do with it. The federal government(in the USA) mandates a minimum quality standard of fuel that EVERY SINGLE gas company is required by law to follow. It is not worth it to splurge for Chevron or Shell gas, they don't do anything different than the cheaper stations. It is a WASTE of MONEY. Even Scotty said that in one of his videos.
The only reason you should ever spend more money for gas is if your car requires premium because it has a high end Turbocharger or Supercharger and is a high end performance vehicle. Outside of that regular gas no matter where you get it is fine for most vehicles.
Does washing and waxing help reduce enough drag to give better mileage on the hwy?
I think so, how much I don't know. When wash and wax your car, the body gets very smooth, and water repel fast, there is water in the air too. Reduce frictions after wax, I I think you get tiny bit better mpg, but it adds up over a year, or the life of you car.
A car with no wax feels rough, after wax, it seals all the imperfections of the paint.
NASCAR waxes their race cars, hoping to get better performance.
Invest your time and money in things that cost less to improve mpgs (correct tyre pressure, maintain the fuel system, drive train, drive efficiently, don't beat your car etc.).
Mr. Skeptical yes don't forget to remove your hood doors and trunk and seats you also make the car lighter and it'll get even better gas mileage
@@nepa3vapeclub297 drill some holes in the frame too
Very thorough advice.
Nice video Scotty... loving it !
