Here in Iowa we have 91 oct and we have 92 oct at some gas stations...Im not sure what the difference is but I do feel a difference between the two. Gas is 3.86 here

Just to make you guys envy something about Iowa....E-85 is all over the place.

 

ya up in north texas its almost impossible to find 93. whenever i drive home from school i always stop at the last station i have found to get 93.

 

I wouldn't mind getting my hands on some 93 just to see what its like. Where are some people from Cali finding it?

 

yes but all that tax money goes to a good cause

 

My car touches nothing buy 93 octane since it was born. I couldn't imagine anything else.

 

After reading this thread I went on a tear and researched what locations in AZ sell higher octane and was successful in finding quite a few. I just filled up with ~3gal of 100 oct and ~8gal of 91. On the way back to work it seemed to run well but looking forward to driving tonight and see if I notice the difference.

I did come across this in my travels and thought others may find useful.

wow in long island its 4.05-4.20

 

...actually its more like 4.30ish last I checked in Nassau LI

 

i throw about half a tank of 93 in my car from the gas station then my buddy brings me 109 every week from work. and i fill that up to about 3/4 tank and the car is down right nasty. i was so close to just tuning the car on race fuel the other day and running close to 400hp.
