First you have to weight engine life against MPG.

Then just experiment.

It's going to take X amount of HP to push a car down the road, trying to extract every BTU from gas is going to leave you with extremely high EGTs. Like Fram says, Pay me now or pay me later.

Driving style, and car configuration have alot more to do with it, then most people imagine.

Not to mention needing to use 87 Octane..
