Hey everyone! So a friend mentioned to me that he uses 93 octane gas in his atv and suggested that I use it in my predator engines. Will this make a difference in performance?

It may be a bit different but, a few years ago, I had a car with a Mazda B6 engine that ran better on e10 (10% ethanol) than it did on pure unleaded...

Take form that what you will...

Ethanol requires a richer a/f mixture, so you probably had it jetted a tad rich.

:wai: Yes, if your comp ratio is over 10 to 1. Otherwise your are just wasting your money.

Just curious as to why so many folks believe that high octane gas or octane boosters
boost performance.
If anyone claims that their equipment runs better on this stuff, then I say engine either required it to begin with, OR there is a potentially serious ignition problem in which case high octane anything would just be a band-aid.

Or they simply have an EFI system that can take advantage of the higher octane, but that applies to practically no relevant vehicle on this forum.

Industrial engines like the predator are designed to run on the crappest crap fuel a crappy amount of crappy money can buy. You wont get any more out of one unless it is very heavily modified.
