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

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.

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!

    Thought your explanation was thorough, but, I didn't hear anything about 100% Gas? I generally use 100% gas in my generator, pressure washer, and lawn equipment. But I also use it in my vehicle's from time to time because of it cleaning property's! And it doesn't have ethanol, and it has a longer shelf life. Can store over winter without drying out and corrodeding in the fuel lines and carburetor. Cost $$ more so I don't use in my daily driver except every once in a while for the cleaning property's. Plus vehicle seems to run a little better when I do! Especially if I run 2 or 3 tank fulls in a row. But I use it exclusively on my small engine utility equipment!

    If it's Ethanol Free, it doesn't matter. Fuel that has Ethanol should be 91 octane or higher. Ethanol destroys engines because of scale that forms during the burning process. Ethanol was a bad idea and the lies have come out 50 years later. I have had the best performance and fuel economy from Shell gas and the difference between < 91 and 91 or greater is very noticeable.

    It is basically the same as fuel with 5% or 10% ethanol. You will notice a little lower MPGs and if your car sits for months it can hold water but the small amount of ethanol makes no significant difference in the fuel.

    Good add on the E-85. Consider updating and talking about the Ethanol free fuel and the benefits it can provide. Ethanol free does have more energy (a little) since gas is more energy dense than ethanol; and it usually provides a small increase in MPGs. However, In my experience, the increased cost isn’t worth the increased MPG.

  63. BamBam Music

    BamBam Music7 päivää sitten

    87 octane is the cleanest. Catalytic Cracking method makes higher octane dirtier. In general terms. Using heavy molecules to create octane instead of the old way of using lead. The higher the octane, the more heavier molecules have been used to get there. Thus, carbon build up. If you can run 87, then do it. Your engine will thank you and not have as many drivability issues.

    Greg Durkee10 päivää sitten

    Higher octane is the only gas to run in today's air cooled motorcycle engines and high performance car engines due to its control of pre destination. Any car or truck that is stock runs well on 87 octane. With that said if your car is feeling sluggish you can run your car down to almost empty and add 5 to 10 gallons of high test to clean out the carbon deposits. Not needed all the time it's like a 6 month interval.
