1995 Tercel. Bought it with 99,990 miles on it. Owner had used 87 Octane.
I NEVER use 87 Ocatane. Filled it with 89 and reset the trip meter. After
a few tanks of 89 Octane, did the calculations and came up with 36-38 MPG
combined driving.

Now, I usualyy don't use 89 Octane either. So the next few tanks were 93
Octane. After a few tanks came up with 44-46 MPG.

Figuring when I owned the car gas was ~$1.65/gallon for 87 and $1.75 for
93, I figure over the time I owned the car I SAVED $220 by using 93.

Your mileage may vary. The only car I ever had that has bucked this trend
is an '89 Mazda 626 I currently have as a winter beater, and it gets
better MPG with 89...
