Since the 6VE1 has knock sensors, 91 octane may yield slightly more power due to more timing advance in some circumstances.Originally Posted by bssage
I say may because the manual specifies 87 octane so who knows - that may be the basis for the mapped advance curve and the knock sensor circuit retards from that baseline - i.e., the upper bounds of ignition advance when the VX is running in open loop were tailored for 87 octane. Bottom line is if you're buying high octane, you're spending a lot more money for very little gain.
Anyway - please direct me to the source of this "No ethanol" info. It's not in the MY 2000 manual, which recommends that you use fuel with ethanol in it "to help clean the air". Are you maybe confusing ethanol with methanol?
And Larson it's lucky for you I don't have time to debate. You are WRONG, pooh-boy!!!!Oh BTW, you forgot this:
