Do This to Get 2x Better Gas Mileage and Make Your Engine Last Longer

We used to know the car was overheating when we saw steam rising from the hood. Then we would systematically go about finding the dead water pump.

1995 gmc vandura V8 3500 mpg 13 in the city and 17 on the highway.
2023 gmc V8 3500 savana mpg 9 in the city and 13 on the highway.

What’s the big reveal?

Scotty,
You gave a lot of good info. HOWEVER, you did not specifically prove what to "do" ('Do this to Get..."). Also, some of your abbreviations are not evident to laymen (ECU, etc).
Thanks for all your other help.

You said about white smoke, would the engine stop the white smoke when it reaches running temperature, if those sensors are going bad?

I used to have a JKU that was eating wheel speed sensors. In 2017 I bought a JKU & lifted it as you do. About 4 months later, the traction control light came on & I lost cruise control driving from LA to Bakersfield. My OBD2 said it was a wheel speed sensor, so I replaced it. 2 weeks later, the sensor went out again, so I cleaned it & greased the connections. It was fine for about a month till it happened again. After chasing the problem, I found it was a bad wire all the way up the line. I replaced the sensor & the wireing harness to it.
I also had a 98 Dodge Dakota that had the transmission input & output sensor go bad when the crank shaft sensor died at the same time. I ignored it because I was broke & the whole thing sized up.

Scotty kilmer: "do this to get this!"
Fans: "what do I do?"
Scotty: tells you everything except what you clicked here looking for
Fans: "OMG SCOTTY YOURE THE BEST NOBODY HAS TOLD ME ANY OF THIS"

Love your shows
This was informative
A little side gig never hurt anybody

Great information and video sir! As always.

I own a 2008 Ford Crown Victoria and I assure you my car is as dumb as rocks. Oh except guzzling gas, it does that quite well...

I love this format from you, you did a great job explaining

The computer chips used in cars are some of the least expensive made. Thank you Scotty.

Good job👍

hai Scotty, What an extraordinary time do you spend on this great informative video. Very creative and good work.

what do you guys think of the bluetooth scan tool? i have it installed but i cant maximize its potential!

Saw video and I'm still waiting for "Do This to Get 2x Better Gas Mileage and Make Your Engine Last Longer" - Tell me, did I fell asleep?

When you pointed to O2 threads figured you meant using the old anti fowl plug extender. I've read you can put one in the O2 bung or nut then put the O2 sensor in that to keep it out of the full exhaust stream. It's old school but probably works. I know you've heard or done that before, I'm as old school as you are my friend !!!

👍👍👍

So, what I have to do in order to make my engine last longer? This video it's full of s...

My 1990 Geo Storm has no OBD port. It is blissful with so little!!

Safety features are great for making lazy, sloppy, inconsiderate drivers.

Still waiting on the info to get better gas mileage.

Hi Scotty I have a 2007 Subaru Forester with 262,000 MI how can I make it more fuel efficient?

No nut November saved me 25% on gas

Hey Scotty, awesome video!
I thought your technical explanations were fantastic!
It was easily understood, very comprehensive, and not too technical so everyone can understand.
I'm a professional embedded systems engineer and work on designing systems with many sensors and programming processors similar to the ones you mentioned. Loved the video!

So I bought a 2001 2,7i Sonata, at the time I didn’t know about the throttle sensor, and the engine, just sent the revs up to 2500rpm from startup.
Not the best Way to start the morning drive.
Luckily the dealer was very nice and the part was cheap, tried to install it myself, but it was stuck on pretty good, but the mechic at the dealer spent 10-20 min helping and Got me a new screw, free of charge.
So I ended up driving it about 50000miles, trouble free after that, Theo I parked it for 12 months, and sold it.
Still miss it.
But all that “panic” do to such a small part…😱😱😂😂

So do you recommend cleaning the sensors or just replacing them?

I have a 2018 Ram 1500 Express with the 5.7 hemi. When I bought the truck it had 12,664 miles on it. It now just turned 40,000.
I've done my oil changes tire rotation and alignment. I have used royal purple injection cleaners changed air filters and normal maintenance.
Why did my gas mileage go from 18.5 to 20 mpg. Down to 15.5 to 16.5?
I drive the same 40 miles round trip every day to and from work. Just don't get it. No lights, warnings or anything else shown up to say something it wrong.

This was AWESOME!!!
Thank you

Thank you brother!

A failed speed sensor caused my speedometer to register zero, a minor problem, but the same speed sensor was connected to the automatic transmission. When the transmission stopped receiving speed information, it shifted into Limp Home Mode and refused to shift out of 2nd Gear manually.
A repeatedly bad camshaft sensor would result in the engine refusing to go above 2300 RPM. When the engine hit 2300 RPM, it would go into a stall and the engine sounded like it was knocking.
A repeatedly bad crankshaft sensor caused the car to stall while starting and also while driving at slow speeds.
A bad oxygen sensor necessitated a repair to pass a government emissions test.
Some sort of a bad fuel sensor was causing the engine to stall occasionally while waiting at a stop.
Bad tire pressure monitoring sensors caused a warning to appear on the dashboard, which to fix requires replacing all of the sensors inside the wheels at a cost of more than $400.

Cars seemed to work fine before all of these sensors and "safety" schemes, and they were much easier and cheaper to fix.

I put a new camshaft position sensor in that only lasted 3 months before it showed up bad again. ECM going bad?

Terrible

We love your channel Scotty 👍

WOW very interesting super kool ,1st class great info.,,, AAAAAAAAAAA++++++++++++ again great video I liked it a lot ,keep up the great work.

WAT 60 TO 1000 SANSOR

Great video scooter

So, according to the thumbnail picture all I have to do is point my finger at it 😅

Love it

What is going to give you the 2x better fuel mileage?

Very interesting Scotty 👌

On my mum's previous car, a 2004 K12 Nissan Micra, the reverse sensor in the transmission/gearbox went bad and the check engine light came on, Nissan replaced it for her and it was fine again after that.

Oh ya the good old sensors I can't recall anytime that they saved me from catastrophic failer on my kia got no lights or anything the engine just dyed got it replace now after a year im having issues with it stalling/ surging dont know what it is it does it real bad if I turn the ac on or defrost.

You can’t repair your own car anymore. You might if you’re Scotty with the right tools. The manufacturers want you to go to the dealership where they charge $150 an hour. The neighborhood mechanic is no more.

I'm not too keen on all the electronics on a vehicle. If my computer can get hacked, so is my vehicle. Just a thought.

still waiting on the answer

Did I miss it? What can I do for better fuel economy?

I'd happily go back to pre-sensor days. I understood everything I was looking at and most repairs to mechanical systems could be done by the average home mechanic in his own driveway.

Merry Christmas to all

My 2002 Nissan Pathfinder (160K miles) began having the Check Engine light flash at me, and then it began running rough. Took it in, had it checked out, one of the coils went bad. Had it replaced, issue solved.
