I've found a gas station close by that sells unleaded oxygenated race fuel. Its 100 octane and its oxygenated with 10% ethanol just like every other pump gas. Do you guys think it will harm anything else to run the fuel??? Here's the product description from the manufacturer: Sunoco 260 GT - Sunoco 260 GT is a street legal, unleaded gasoline designed for high performance street cars, muscle cars, classics, street rods, motorcycles, karts, and marine applications. With a 100 octane rating, Sunoco 260 GT will allow significantly increased boost levels in supercharged or turbocharged applications. Sunoco 260 GT contains no metallic compounds to harm catalytic converters or oxygen sensors. It contains a comprehensive additive package for greater engine protection and reduced fuel system deposits. Sunoco 260 GT is also compatible with virtually all two-stroke synthetic and mineral based motor oils. | ||

Unless you are running very high compression, I don't see a reason why you would need it. Maybe a splash for very hot days would do some good, but if you fill up with that stuff, your motor might not run so well. 91 or 93 should work well for the motor.

I agree with boltrider. There would be no benefit from running the higher octane, unless you have super-high cylinder pressure, as with a high static compression ratio or some type of forced induction such as supercharging or turbocharging. There shouldn't be any negative effects, just wasting your money. However, doesn't Buell recommend against oxygenated fuels? Maybe somebody can back me on this... | ||

I understand what your saying Boltrider, but the bike sure seemed to run better, more acceleration and roll on power. I just don't want to damage the engine. | ||

As has been said, any effect is most probably just between the handle bars. Sometimes a higher grade gas can make an engine run a little better if its current state of tune isn't right on. But that as you might conclude is just a mask. And no...it will not hurt anything but your wallet. Mike | ||

Oxygenated fuels actually produce LESS power than non-oxygenated fuels. You also get less mileage out of it. What they do is lower tailpipe emissions. That's about it. I always get far better mileage when I tank up outside of New York (where the gas is oxygenated year round, just like in California). | ||

Thanks for the info guys. Looks like I'll be going to 93 octane pump gas after this. Just wanted to give it a go. | ||

A few clarifications: almost all fuel found at the pump is oxygenated. Non-oxygenated fuel will almost always run better in our bikes and in most cars. The EPA mandates oxygenated fuel because it burns differently and therefore produces less carbon monoxide. That aside, some of the above are correct in saying that your bike will not produce more power on 100 octane then on 93, I have typically found that mine runs better on the occasional tank of 100 (although my source supplies non-oxygenated 100). Again, not more power, but better running- smoother acceleration, snappier throttle, less off-idle stumble. And no, you won't hurt anything. I run a tank of 100 about every 7-8 tanks. |
