Second I feel with the FJR's compression level being 10.80:1 the higher octane will achieve better performance, dog pile me baby. :clapping:
Ok, I'll cede the owner's manual verbage.
Now, on to bigger and better things.....
You 'feel'? Freakin Kali treehugger. You 'feel'!!!
Never mind all those pesky engineers who are telling you that 86 octane is PERFECTLY FINE. I guess you know more than them. There is more than just compression ratio to consider in determining what octane an engine runs best on. Try out some your search skills and look for posts by 'Jestal' among others in the
plethora of octane threads on this site. You might learn something.
Your FJR is not going to achieve any better performance by putting high octane gas in it. Nope. T'aint happening surfer dude.
Now, go try a Fitch Fuel Catalyst if you really want some more mo-jo in your go-go juice.
