That is weird you got better with the 87 because I used to have a pontiac transam that required 91 or bettter. I was in the middle of nowhere Iowa and all they had was 87. My engine light came one within 20 miles and it ran like crap. Bad gas? Maybe. I don't know....I have had all GM cars for years now. I don't know if that has anything to do with it. I currently have a Cadillac CTS, Deville, and the Hummer. I also have an early 90's model 2 wheel drive lowered step side Truck. with an old school 350 and glass packs, LOL! No difference on the old truck.

 

That is dedication to do that much typing on a phone. I have a Treo and keep my e-mails short and sweet. Put me on a full size keyboard and I can type up a storm.

 

I would love to try your experiment LisaM with my Ford F150. I want that extra gas mileage.
