What octane gasoline do you use the most?

Fill 'er up!

I still use 87 right now, might still have to stick with 87 for daily use and switch to 93 for the track. I might continue to drive the Escort to work and back for the summer though. If I do that I'll change the Mustang to 93 only.

Sounds like a good idea to me!

i drive on booze and the car on 89

I ran 100 at the track a couple times and honestly, I saw no difference.. I think unless the car is tuned for that kinda octane, you're not going to see much of a difference either, except in the price.

Gotta run the 91 in the Bee! I always get stoked when I get to put in 93 (even though there's not that much defference), but ya never know which station offers what.

Before racing season starts, I'll be getting some tune files for my SCT 2 that will allow me to run on Premium. Currently the car is un-tuned, need some new files for the stick shift car.

changing from 87 to 93 will make a difference especially with a predator.

93-100 you won't notice a difference but if you ran 103+ with a tune you would see it. i run anywhere from 100-110 in the camaro. and depending on the fuel depends on the animal that shows up.
