    Rec 90 fuel

    A gas station on my way toward the lake has 4 pumps that offer rec 90 non ethanol blend fuel. Are you guys using it. Is this offered much any where else? I know the other morning before a tournament guys was using pumps that didn't have the rec 90 option ( maybe. They was unaware? Or just didn't want to use it?)

    I buy it my motor manufacturer recommends against using ethanol, but it can run on 10%. Some knock it because it isn't 87 octane but I'd much rather use 3 points more octane than 10% ethanol.

    If I recall correctly,90 premium burns slower than regular 87,therfore you'll have more carbon
    build-up as reult of unburned fuel. I use 87 octane as recommended by Yamaha Owner's manual.
    If your motor is out of warranty use what ever you want.

    Use it all the time. More and more stations are starting to carry it again. Try this web site. pure-gas.org

    burns cooler and with more spunk therefor better milage and less carbon "like thats a problem with good oil"

    I have a 4 stroke with variable valve timing and a computer that continuously adjusts timing if necessary. With the disappearance of tetraethyl lead in gasoline, there are far fewer deposits, especially in 4 stroke engines.

    I have used it exclusively for years. Mechanics were relieved when I told them I use it.

    It costs more is more than likely the reason some people don't use it.

    Yamaha manual actually says MINIMUM of 87. 90 is fine no matter if you have warranty or not.

    In canada here we have 91 and 94 both non ethanol blend, it is actually harder to find e85 anymore, i think shell 91 v power in canada and USA is totally ethanol free, i dropped the CR from 150 to 130 on my 2.4 hi strung bridgeport motors and run the shell 91 or our sunoco 94 with the best oil Klotz techniplate and have no issues, ethanol is a killer on older 2 stroke mercs efi and carb.

    Maybe for a 4 stroke but you dont wanted a cooler slower burn in a 2 stroke. The less carbon the better. In my opti I run 87 with Dons cocktail. Never had an issue and its a screamer.
