We've had 10% ethanol in this area for many years. Initially, very old cars had lots of fuel pump trouble, due to rust in the fuel tank being drawn through the line. I doubt that this will be an issue for you.

No

problem,occasionally until the ecu adapts the extra oxygen in the oxygenated fuel may trip the telltale p0170 and p0173.It will clear itself.

"Underground" gas? Do you mean aviation fuel, or something someone brewed up in their back yard?

In either case, it doesn't matter. Too much octane won't help you at all, and dirty fuel could cost you a lot.

Plus

to high octane burns at a different rate and the car will trip cel codes.You should be on 91 or 92 premium fuel though.

See how it is measured. We use (RON+MON)/2 here in the US. In Europe, they use RON alone, and the same gasoline there measures much higher than here.

I've been running 94 octane in all my Mercedes for at least 5-6 years now. It contains up to 10% ethanol. Zero issues.

No, (R+M)/2, same as you guys. Only gas station up here that has it is Sunoco, it's called Sunoco Ultra 94. Other reason I use it is that it has the highest amount of detergents, etc.

Sunoco 94 used to be available here, but I haven't seen it in well over a decade. The best I've seen for automotive fuels since then is 93, although there are places near water that sell 100 for boats. Airfields have higher octane fuel, but you can't pull your car up to the pump.

I can't help you with that one.

But I can tell you how to measure ethanol in your fuel. Take a 20cc graduated tube and fill it with 10cc of gasoline. Then add 10cc of pure ethylene glycol (antifreeze) and shake vigorously. The alcohol from the gasoline will dissolve in the ethylene glycol, which will seem to expand beyond the initial 10cc. The difference is the ethanol content.
