    How you drive makes a huge difference. The long term average mpg on my car was 26.4 mpg. I let my lead footed gf drive it for a week and she reduced average mpg to less than 20.

    EPA claims my 21 Rav4 LE fwd 35 mpg Hwy. When I bought it New, the dealership forgot to air down the tires , 50 psi, BUT it got 43 mpg on my drive back home. It's currently at 56k miles and I Always keep the tires at 45 psi and I drive mostly on the highway. Even with weight and OEM roof rack my fuel economy is consistently 40-46 mpg; I verify at the pump ⛽. I get 45-46 mpg with A.C. ON. My record is 48 mpg Turlock to San Diego Feb 2024. 😂😂😂

      Do your tires wear unevenly down the center line?

    • @lamesamelame
      @lamesamelame 6 часов назад +1

      @AH-bm4ts The original tires Firestone Destination LE 2 has slightly more wear in the center. I rotate them every 5k miles. Warranty is 5 years 60k miles. At 56k miles with tread is still above the wear markings. I haven't measured exactly how much but based on my personal experience, No major adverse effects for my current vehicle.

    He forgot the most important point. If you want to use less gas, drive less. Combine errands on your trips. Ask yourself, do I REALLY need to eat out tonight? Eat at home and save tons of money (in addition to saving gas). And so forth.

    Good video David , these are all valid and usable points, that i have used for near 50 years of driving and the biggest ones, tire pressure, tune ups, driving habits, my daily is an older Volvo 240, 98% highway driving and i still get within 2 mpg of the factory rating with over 420kms 👍

    I live in South Africa and downsized my car from a Ford Kuga to a Toyota Urban Cruiser. I did this because both our children left the house and have their own cars. We did not need the bigger car aby more. I miss the Kuga's power but the fuel consumption in this Toyota is excellent at around 15.7km/liter. I also do a lot of bass fishing so needed a higher vehicle to deal with some of the dirt roads on the farms i fish. I wanted to buy the Corolla cross but is too low. Some really good comments given here but i also believe the way you drive (heavy foot) and tyre pressure stands out for me.

    David, I agree with all your 'factors' but I have a fuel efficiency strategy that is far more RADICAL to add to the list: I actually treat the speed limit like a .............speed limit.
    In other words, if the sign says 50 kmh, I drive 50. If it says 80 kmh, I drive 80 and craziest🤪 of all, if it says 100 kmh on a four lane highway, I drive 100.
    I describe this strategy as radical because hardly anyone is doing it. BTW all my crazy, slow driving is done in the slow lane. 😉 Speaking of crazy, have you ever
    noticed the most aggressive and careless drivers are the ones who complain the most about high gas prices? 🤔

      @kingofthesofas 8 часов назад +1

      On this point I have a new land cruiser and at 55 mph I get about 5 mpg better than 75+ mph. That boxy design really does have a lot of air drag at high speeds so just slow down a bit and you will save a lot of gas

    Good tips, David! With a hybrid system, doesn't the start/stop function and driving around town cause more water to be created which can get into the oil? It seems like the engine never really gets the opportunity to come up to a normal operating temperature which would allow it to burn off the water caused by combustion. Thanks.

    Probably one of the biggest things I can think of is not to buy a 4Runner (17 mpg) or a GX (16 mpg) especially if you're an urban cowboy who buys it just for the image. And don't buy a car that uses premium fuel. Who cars how tight the body panels are?

    • @bngr_bngr

      That doesn’t apply to the current vehicle a person owns. People need to haul around a bunch of people and their stuff. They will never buy a Yaris.

  • @pedrofernandez8729
    @pedrofernandez8729 8 часов назад +6

    I don't agree on using premium unless the car requires it. Premium on my little Yaris is wasted money. I get neither better mileage nor performance.

      @@bngr_bngr As David has explained in previous videos engine oil is one exception to following mfg guidelines. For instance vehicle has oil quality (%) then it oil/filter is best changed at 50 vs a lower number (%). I would think his thinking for premium gas is a little "out there" especially since he advises against racing /driving too fast. Hilly terrain can be a gas hog and long stretches of level or even slight downhill driving can improve efficiency from 7.5 to 6.5 L / 100 km in my experience. Thanks for these tips David.

    I don’t agree on running premium for better gas mileage. Lower octane burns more efficiently = better gas mileage. If your car calls for premium that’s what you should use.

  • @ericbrummett8515
    @ericbrummett8515 8 часов назад

    Another You tuber said it is not good for the internal components of the engine to run higher octane in a car that isn't designed for it. I think one of the reasons was that it burns hotter.what are your thoughts on that. also I'm wondering if you should run higher octane once in a while to help clean the system without buying additives.

    • @fahedsayed2201
      @fahedsayed2201 7 часов назад

      premium fuel has cleaning agents and it cleans the engine but if your car is not designed for premium you can just do a 90/10 ratio or 80 20

      I would go with the manufactures recommendation for gasoline, oil type, etc. Now when it comes to oil changes, I do half of what ever the manufacturer recommends. 5,000 miles or 6 months is best. My dad was a mechanic at a VW dealership, he changed the oil in his car every month😂. We only lived five miles away from the dealership.

    Thanks for the tips. The start/stop, I'm glad my 2024 Cx-5 doesn't have it or the cylinder deactivation. Maybe I'm old school but I just don't like it. The only time I want my engine shut down in the middle of traffic is if I have to shut it down. If it does actually save a little gas, I'm ok with passing that by.
    Good video, thanks.👍
