I learned something new from it tonight.

i use 69 octane
I get premium, only the best for my skank, car runs smoother and I get better gas mileage.
I have read many other similar articles.Originally posted by tom3

According to this author, if "your compression is 9.5:1 or lower, 87 octane should be plenty" then our car which runs 9.8:1 (correct?) would be best served by running 89 octane...??

Always Chevron 87 oct. Gonna bump it up to midgrade 89 for my next tank. I get some pinging at the top of 3rd gear. Hopefully that will take car of the pinging. I'd hate to have to buy 91 premium because it's about $.30 more expensive then 87 around here. One of the reasons I bought this car was the trouble free good performance with crap low grade octane...so much for that benefit.
I would love to see more literature or a nice grit about compression ratios vs. octane ratings. Anyone? I'm looking around, but haven't really found anything valuable yet.Originally posted by Gs02SiR

94 octane chevron
I just realized I didn't answer the questions - 87 Rotten Robbie mostly. Gas is gas in California. It all comes from the same 3 refineries. The big names throw in some additives, but ... well ... don't care.
the cheapest 87 that I can find, which is usually at ARCO/AMPM
