  • I wouldn't even begin to know where to find non-ethanol fuel

  • Use any you want but mix with marine stabil to reduce the corrosion that ethanol leaves in fuel system .do not use regular red stabil as that does not work

  • We do

  • Regular. No benefit in running higher octane. The engines aren't designed to run higher grade. While it won't hurt anything, you get NO GAINS vs regular. Y'all are wasting yalls money.

  • Page 10-2, bottom left corner:

    "Regular Unleaded gasoline only"

    Higher octane is only beneficial with higher compression. And regular unleaded is said to be 70-80% fresher in the tanks because most people run it where super can sit in a tank for months. Just something to think about

  • These engines run lean from the factory, after adding an exhaust and even a programmer it's piece of mind knowing your not gonna get detonation from running low octane. That's why I choose to run premium

  • Ethanol just eats the hell out of anything plastic if it's in there awhile. Such as a float in the tank, it will eat away the float and it will be at the bottom of the tank. Happened to my uncle on his sled

  • Nonethanol only

  • That's what I have been told so I run 87

  • Only reason I run 91 is it is the only no ethanol fuel I can buy.

  • I run 91 for peace of mind. Shell has the most detergents to help keep your engine clean so I use them. Price difference from regular to premium isn't that much so it costs me an additional $10-$15 bucks a year for peace of mind. No big deal.

  • Ethanol collects water and causes alot of problems.
