E0 or avgas

My approach now is to accept it and boost fuel delivery to work better with it (4% more fuel needed plus whatever else you choose to add, 6% in my case). 10% more fuel takes about 20% higher fuel pressure and a shift in the O2 sensors lambda setting from 1 to 0.94. Ethanol works fine. Here's a racing article: Ethanol in Racing.

The WHO has determined that MTBE is NOT a carcinogen. It is still used as a fuel oxygenate in other parts of the world with success. Also, it is made from low cost natural gas, abundant here in the US.

MTBE was finding its way into ground water around leaking fuel tanks and imparting an undesirable taste and odor in groundwater. Instead of mandating the repair of the leaking tanks (a rather simple solution), the EPA mandated ethanol replace MTBE.....and, the rest is history.

BTW, your boxer is not powered by an airplane engine nor can it fly so, don't use AVGAS. Listen to Anorak....he knows.

All good I didn't take it as such.

I fly airplanes too. You don't want avgas, at least not 100(green) 100LL (blue) or 80 (red). If you happened upon some 94UL, which is basically avgas without any lead in it, your bike would probably like that stuff. It is mostly alkylate, which is the best fraction from refining gasoline. Burns clean, has a high detonation resistance, has high thermal content.

Trouble is, it hardly exists. I think you can get it in a few places in Europe. But it is rare, rare, rare stuff. You'd have better luck looking for 200 year old cognac.

Interesting info. Thanks Roger for making me see my issue...

I haven't accepted it! ( especially when they're pushing E15)
Concerning Greece & Spain, I'm not sure they would get what a bad deal it would be. Look what else they buy into...just saying...Oh, my apologies to all inmates in Greece & Spain

BMW does not recommend two hundred year old cognac in the boxer engine.

But apparently schnapps is fine as long as you add a little gasoline for cold starts ...

Another very effective octane booster is MMT (methylcyclopentadienyl manganese tricarbonyl)



used in Bardhal Instead O lead Gold, which I think you can still get and works excellent.

I used to have a old Buick that liked octane. It was OK around town, but if you hit the highway it would rattle bad at high speeds. I kept this in the trunk, one bottle in even a full tank of 26 gallons stopped all the pinging. Good stuff.
