What is the BEST Fuel to Use in Your Car or Truck and WHY

  • Published on Oct 15, 2019
  • Ever wonder what grade gasoline should you use in your car (what octane)? Are you paying for premium gas when you can just use regular? Are you using regular and damaging your engine? This video will bust all of the myths and tell you the FACTS on what fuel you should use and why.
    Many people throw money away and fill their car with the incorrect fuel every day. Running premium or midgrade in a car designed to run regular is a waste of money and has no HP or MPG benefits. You will not make more power or get better fuel economy running premium fuel if the car manufacturer tunes the car to use regular gas in most cases. I also see some people run regular gas in cars that need premium and the knock sensors have to adjust timing significantly to prevent damaging engine knock. I also hear a lot of people say that premium gasoline has more energy or burns cooler or slower so I will put a rest to all of these "myths" with facts.

    I hope you guys like the animations and all the extras that went into this video! It took a while to do (you guys who follow me on Instagram know lol) but I think it is worth showing you examples instead of just taking my word for it! For those asking, here is where I got the fuel injector cleaner/tester: amzn.to/31kHwhk

    gas is gas, it all comes from the same tank farms.... octane many vary but brand names do not!

    • saint chuck
      saint chuck 13 hours ago

      Yes, they do. The base gasoline grades (85 and 91) are the same for any gasoline loaded at the same terminal, however, each brand has separate additive tanks that get injected during loading.

    How about 91-octane pure gasoline? You will get better fuel economy with it than 87, or 91-octane E-10, which is 10% ethanol. The pure gasoline has 25% more btu, or heat units, than ethanol blends.

    i'm pushing sixty now, but, my dad was a very good backyard mechanic, as everyone in the neighborhood and others he knew brought their cars to him to be worked on. he swore by high test fuel. every car he owned, high test gas was bought, even the last new car he bought in 1974, a bug eyed, matador X coupe. he told me over and over, high test is better overall. remember, his last car he bought new was during the gas crunch of the 70's and gas still had lead in it. even when they took out the lead, he didn't like that at all, something about the lead helped to lubricate the valves and such, he still swore by high test. well, when i started driving, there were still long lines at the pumps and gas inching up to over a dollar a gallon, making people buy regular gas instead. people had issues with their cars not running well. i took my dad's advice and still to this day, put premium fuel in my vehicles, including my lawn mower and rider. i have less issues with my vehicles, less maintenance, and get better mileage, especially, when making long trips. i don't ruin my vehicles putting cheaper, lower octane fuel in them. don't get me wrong. i have had hard times and was forced to get regular fuel just for the cost saving and regretted it after several hundred miles. the rough running, the lack of power, the mileage loss and eventually, changing plugs and oil at sooner than normal intervals. running premium fuel also saves valve cover gaskets. not sure why other than the vapors from in the crank case. regular fuel tends to cause these gaskets to go bad sooner than using premium. my experience and i'm sure there will be those out there that think i don't know what i'm talking about, but, either way, my experiences are true. premium is better for any car.

    Didn't watch the video, but common knowledge is to NEVER use mid grades. Most people either buy the cheap stuff for economical reasons, or the high grade for performance reasons. The mid grades tend to sit in the tanks for extended periods of time and degrade. They get sediment and other contaminants in the fuel from sitting so long as well..

    The real answer though would be what ever the manufacturer suggests for your specific engine as each one is built differently and has different requirements.

    back here in Sweden the price on petrol and diesel has gone from about 3 dollars to 6 dollars for one gallon, and they want us to rebuild our engines so it can handle the the E85 i dunno it is weird here in Sweden. But with E85 the car uses twice as mutch as it would with regual petrol, Our diesel consumes half as much as regular gasoline and has almost half as much emissions, but the Diesel cars are taxed almost three times as high as a gasoline car

    Truck - diesel😉
    Gas - ethanol free. Avoid the water problems by avoiding alcohol in your gas.
    And FFS please stop blocking the diesel pumps to buy gas when there are 6 million gas options and only 2-4 diesel pumps at the huge gas stations.

      E85 isn't an octane rating. It stands for 85% Ethanol.

    The fuel during winter is mixed with propane to help vaporize, less density than in summer fuel. You get more mileage with summer fuel. Premium fuel doesn't get any propane, the density is the same year round. I use regular fuel in summer and premium in winter, to get best gas mileage

    Can you tell me why I can only run 93 obtain gas from Shell or one of the other higher priced stations and why I cannot buy it at the stations where it is cheaper. Should 93 obtain be the same anywhere that I buy it. I am running a small block 383 Chevy in my 84 Camaro Z/28. I don’t ever buy the cheaper priced gas because of the knocking.I did at one time run 94 but I cannot find it anywhere now.

    you completely forgot the most Important Thing, the owners manual will tell the exact grade your vehicle will need to run at the most efficient level. it is in every owners manual. most 4 & 6, some 8 cylinders even, will run on 87 octane with no detonation or pre ignition. over the years, manufacturers have created bigger & better engines rated for a much smoother drive with turbo chargers etc, can lets say 87 octane with no problems. that's a true statement. I've seen it, drove it, ran it etc. your engine has got to be rated at Higher HP, Torque etc for the application and purpose it will serve. the engines have only achieved about maybe less than half great fuel savings anymore, plus now we have the single overhead and double over head cam, or roller cam engines which create the Horse Power in a more efficient and better way yielding a smoother running engine that has some ass to it as well & these engines would or could all be, 4, 6, 8 cylinder engines. higher octane does't do JACK anymore like it use to because these newer engines are designed to run more efficiently & with more get up and go.


    Wow good stuff, my car is funny because it's true that it says it takes regular but the specs in later years updated to say premium recommended (same engine) and the car feels better on shell v-power so I'm gonna use that especially since it's a plug-in hybrid and the engine sets around allot I'll just do it and it just feels better to me honestly.

    Hi Chris, I own Hyundai Verna 4s Petrol 1.6 variant which has been standing for almost a year. Car is just 5 years Old. What precautionary measures should I take to make sure engine stays healthy. Does Petrol cars have any problem caused by RUST inside (if this happens) the engine if the car was not driven for this long time, do you recommend changing the OIL after few kilometers now?
    Please suggest. Thanks
