Stop in for a cup of coffee
So that's the limit for your gas? Is that 91 octane?
We get 95 or - in fact - 98 unleaded over here. Not sure how much ethanol it has but I think it's 10%. Could be 20%. I've been told that the limit in static compression therefore is 10:1.
We can get 87, 91, and 93 octane at the pumps.
Anything more is considered "racing gas" and is 4x the price...
the 93 octane is almost a buck more expensive, so it's best to build a street engine to handle the crap 87 octane....
Here in Chicago, we are into the "summer blend" which is supposed to reduce smog, so we don't end up smoggy like Los Angelos, California.... It's an excuse for them to jack up the price on us....
Not to mention that Cook County loves to tax the gas, liquor, and cigarettes - they love those "sin taxes"....
They also raised the sales tax 1% this year...
Tax, tax, tax, tax, tax, tax, tax, tax, tax, tax, tax, tax, tax.....
