Whats up guys, been getting slow on this board so i thought i'd ask a question. Anyone know where i can find 91 octane in the greater philadelphia region--philadelphia, bucks, and/or delaware county?? i cannot seem to find it anywhere. only 87, 89, 93, and 94 octane seems to be around the area. considering gas prices and the fact that you supposedly get better gas mileage out of 91 over 93 i'd much rather fill up with that if i could find it.
thx in advance
ps: when is the next philly meet? getting nice out

 

hmm do they have a Valero gas station out in philly?

 

never heard of it, so i guess not.

 

I never even knew that 91 was sold until I was working in upstate NY a couple years back. You have a couple alternatives in this area, either use the 89 or figure out how much fuel you need and fill half 89, half 93, and you have your 91.

 

yeah, i'd heard that...so thats really safe huh? ok, i guess i'll give it a try. but the 89 by itself isnt safe though.

 

I can not speak for every station, but I know some only have two tanks and if you select mid-grade the fuel is actually mixed right at the pump. I agree, I wouldn't run 89 for extended periods either. The engines these days are so advanced that the knock sensor will adjust the engine, but I'm certainly not going against the owner's manual to save a couple $$ on gas (at 500 miles a week it's more than a couple $$, too). But I'm sure that info has to be recorded on the ODBC.
