Thank you TFL for diverse and interesting content. It’s nice to see other vehicles that aren’t always the latest and greatest EV or Supercar.

I'd be really interested to see this turned into a mini series where you did an oil change (maybe with a modern fully synthetic oil), removed the roof bars and topped the tyre pressures up. I appreciate you'd get diminishing returns so maybe doing them all together might be nice to see a potential jump in economy. Either way proof that basic maintenance is key. p.s. Calling a tune up seems a bit strange is a US term for a basic service?

fun video idea: slightly lower tire pressure mpg vs good tire pressure mpg, i think it makes a huge difference and such a simple fix + added benefits of not wearing out your tires

[cummings]

Not gonna lie, as simple as these videos are they are enjoyable to listen to or watch. I think a car maintenance series would be a good thing for the fleet!

Also, there are other things you can do to help your MPG, like removing any roof racks on the car that you're not using. Making sure your tires are properly inflated is another thing to help MPG. And for the love of God, service your transmission and replace filter/fluid at least every 100K miles.

Our 06 Highlander AWD limited has 332k, runs great. At 247k I tuned it up cleaned the throttle body, changed plugs, cleaned the engine air intake, changed coolant and nmany other things. Heading for 500 k!!

I love Brendan being included more. He is great.

Great experiment and solid information on auto maintenance.

I love these types of videos you guys do on the most common cars on the road, cars that everyday people drive. I have one of these Rav4's and they are excellent vehicles. Thanks TFL for your great content!

[Desertfox]

Two other things that would affect MPG, Oil change/tire pressures. Very nice performance for the old RAV👍

I had a 1999 Toyota RAV4 that I used for deliveries. I was hard on it all the time everywhere I went and I could still average 25-27mpg and the person I sold it to has it up to 220k miles now I believe

It's not recommended to change spark plugs on a "scalding hot engine" because aluminum gets very soft when it's hot. You increase the risk of having cross threading issues.

Basic maintenance is always key. Recently, I had the fuel filter, air filter, spark plugs, oil change and coolant change in sddition to timing belt and water pump done on my 99 Impreza. It did wonders to the fuel economy and the car feels much more alive. It was well worth the money and overall will save me money in the future with the better fuel economy

[Sunnysky]

You got a 8.8% MPG increase. That's about right. I changed my 2012 Prius air filter at 11k miles, and noticed the MPG bumped up from 51 to 56.

I am not a subscriber but I absolutely love these videos about old simple Toyotas and Hondas. I am a big fan of those cars. I hope you guys can do more videos about these please thank you 😊

I recently took a long trip during the holidays, I changed the transmission fluid and wow, my car went up 3MPG on the city and like 8 on the highway. Granted I changed the serpentine belt and aired the tires but other than that. I was pretty impressed.

[juliobello]

This video really teach people that regular maintenance can safe you money and how important it is

More content on 90s and early 2000's vehicles please! I love it and it's more relatable!

Two additional suggestions:
1. If you can find it locally or order it online, pour some ATS 505 CRF Pour-in Treatment into the gas tank. A New Mexico friend of mine (ATS is in Albuquerque) has used this in numerous high-mileage vehicles and says it works wonders cleaning the fuel injectors. And, if that does not make a difference in how the vehicle runs or does not improve its fuel economy, then . . .
2. Replace the fuel injectors. If they have not been previously replaced, at 200K+ miles, they probably need it. And they are not that expensive.

One point where TFL misspoke--in a non-turbocharged fuel-injected vehicle, the vehicle will actually get BETTER fuel economy at high elevation. Why? Because the vehicle's computer will lean out the fuel delivery to the engine to compensate for less combustion oxygen being available. The vehicle will have less power (about 3%-4% less for every 1, 000 ft. of elevation), but the vehicle will get better fuel economy.

I read a comment about worn-out tires versus new tires. There is greater friction with new tires, so mpg might drop a bit. Also a lot of air cleaners are changed when dirty. The key word should be if the air filter is still serviceable. K&N did studies in this field, and so-called dirty air filters have better flow than clean ones.
