You gotta love people that base fuel consumption on 1 f**kin' data point. Get real. You can drive the same exact 400 mile stretch of road 20 times the same frickin' way and still get variances on 10% or more.

FAIL!
yeah... my mpg is higher before lunch vs after lunch. is it the cooler morning air my engine is breathing or is it the lighter weight before my macho burrito combo?

I have ran both 93 and 87 when at the track and it has NO effect on speed what so ever. Unless you tune, you're wasting your money.

+1. The only way a 4.0 is getting 30 mpg is downhill, in neutral, with the wind at your back. I usually get between 18 and 20 in the city. No way 30 is legit.

I'm still trying to figure out how you derive mpg from the speedometer. You just drive until the the speedo wont go past "0", then you know the tank is empty?

FYI, the typical on-board is off conservatively by about 1-2 MPG. Not everyone but definitaly the vast majority. You need to hand calculate your fuel mileage to get an accurate figure.

Have you verified your speedometer with a GPS? I'm tempted to say that your speedometer is off, too, compounding the problem. And if it IS off, then hand calculating won't yield accurate results since the odometer would be off, too.
