Regular tho I've put the middle grade in my car once by accident lol

 

i use the regular stuff, but any car with a knock sensor should increase the timing with better fuel and make more power/economy

 

Premium in the Grand Prix GTP for me.

 

bronse is running at 83.5 right now so its that for me

I put the gold in when the chips in

gas is crasy money up here

 

middle grade most of the time, and regular when i'm strapped for cash [img]smile.gif[/img]

 

I read a couple studies that say that there is 3% of cars on the road today that benifit from anything above regular 87/oct.

My car gets me from A to B with 87, and the cash I save goes to the stereo!!! [img]graemlins/thumb.gif[/img]

 

I put the best their is! ALLWAYS!!! why not work pays for it in my benifits plan. they give me a gas card and I don't have to claim anything for taxes.

 

A most sane approach. I use el-cheepo on long trips (little acceleration just cruise control) and premium around town (my car is one of the 3%) but I get 30 mpg highway!

 

In my Grand Cherokee I use regular most of the time 'cause if I used premium I would have to take out a second mortgage (I filled up yesterday and a tank of regular cost me $65.00).
In my Accord EXR I use premium and get better performance & mileage.
