gasoline whit ethanol !!!

[larces]

i friend of mine shock me whit the notice of that the government will star to put 5 % of ethanol on the gasoline this will affect my engine ? i will have to put some aditive to the gas ? some one can help me whit this questions

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.

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

thanks guys my soul is in peace, another question here the gas is 89 octanes but i can guy also "underground" gas whit 120 octanes and they say is oxygen fuel ? can i mix the regular 89 whit the 120 ? or is bad for the car ?

[Matt L]

"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.

[larces]

jaja underground is because hear you cant buy aviation fuel or vp fuel but i mean vp fuel is the one that they sale to me i know that they sale coctales but if you shacked and dont get cold it´s a estrange elixir

[ohlord]

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.

[larces]

but the fuel over here is as far and whit luck get to 86 any suggestions

[Matt L]

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.
