How do you "know" that it burns cleaner? (Hint: It doesn't.) Every engine is different. What applies to other bikes may not apply to yours. Do you know about the placebo effect? ![]() Botton line: Use whatever makes you happy. The cost difference in your GZ won't be significant. I'm sorry I brought it up! :cool:

I have now run about 5 tanks of 89 through my GZ, and the only difference I can see is that I'm about $1 poorer. I can't find any difference in the engine and nothing much in mileage, either. I might try 91, just for the heck of it. I have an extra couple of dollars this week....

Back on 87, I just achieved my 3rd highest mileage over the past year at 67.64mpg.
89 was giving me 64s. |

Here in Spain we've got only 95 and 98 octane gasoline, and it's very very expensive. Nowadays, it's around 1.5$ for 95 and more than 1.6$ for 98. :cuss:

Erm, yes, sorry. That was dollars per litre... :oops:
So, it'll be about 5.7$ and 6.1$ per gallon.

Modern lead free fuel burns clean. Even without fuel injection to make things almost perfect a well carburated bike will run well and clean on the cheapest gas. I would rather spend the extra on a hi dollar spark plug and ignite the mixture even better than before. Efficient combustion is what keeps things cleaner. Just use a major oil company product that sells well and the underground tanks always will have fresher gas. Seems to work for me.

for shits and grins I tried E85. For those who don't know E85 is 85% Ethanol 15%Gas ~105 octane. It was worse than I expected. It barely ran. had to use the choke to keep it from stalling and couldn't get over 45 mph. I guess this shows how lean these bikes are setup. the ideal air fuel ratio for E85 is about 10-1 where gasoline is about 14.5-1 so it would make sense that it would just run stoopidly lean on E85.

I was considering a complete breakdown and conversion to run on E-85. Thanks for the info.
