I'm with Speed_demon24 on this. I once put in 87 just to see what would happen. I only got 190 miles to that tank, driving the same way I do with our 91 premium. Usually with 91 I get around 230-240. Performance sucked as well.

Use premium.

I will try the 91 and see if it makes a difference, I was getting around 18mpg between city and some highway driving with the 87. Wont be until spring though, car is off the road for the winter.

My GF's 95 TA LT1 says on the fuel door "Premium fuel recommended".
