what fuel is best

[CirclesCenter]

I run my bike on diesel fuel, I get awesome mileage

Make sure to use the low sulfur stuff.

well the lowest i have ever seen is 92 octane

dose the bored look diffrent or is my computer just tripping fun bags

our octane ratings are calculated differently than the rest of the world, so your 92 is probably the same as our 87.

...and you're probably just on drugs

In the UK we have standard Unleaded (95 RON) and Super Unleaded (98 RON), so even the lowest standard is a decent RON.

I run mine on 98 RON in hte hope that it will be nicer to the valve seats and make my engine last longer - but I can't say I have noticed any performance increase, compared to standard 95.

Higher octane isn't any better for your valve seats, the reason some people think that is because the old leaded gass may have some benefit to the valve seats. All the stuff you can get for the street is unleaded so the octane has no effect on the valve seats.

Talking to some old mechanics/pilots flying old radial engines, they add a little 2 stroke oil or marvel mystery oil to their (leaded) gas. they are convinced that it's good for the valves, especially the valve guides, and the cylinders and rings.

I tried using a little 2 stroke oil in my bike for a while (about 100:1 or less) and I noticed that the bike seemed to use absolutly no oil while I was doing that. Maybee the rings seat a little better  but I'm going to use some marvel mystery oil and see if it dose the same thing. besides, it smells like buble gum
