I set the cruise for 57 and get phenomenal mileage compared to 65+. I know, it takes a lot of self-control, but if you can do that, I can almost guarantee an improvement (the wall of air over 60 mph takes more energy to move, as does 70, which is exponentially greater).

If you're car only needs 87 octane, then anything more is throwing money away -- it won't do a thing. Now, if you install a Hot Air Intake (HAI or WAI), then going up some octane points may prevent knock and detonation -- otherwise 87 is fine.

Does your GXE have more extras (meaning power windows, etc.) vs. the XE? There may be a weight difference...
