i have kind of a lead food also they are shorter drives so the engine doesnt warm up that often
I get 22mpg* driving 55 mph on the highway. Preloader gets 18mpg. You getting 24mpg you are slacking, put some more bolt-ons into that car, lower your tire pressure, WOT more often!
*I get 154mpg of gasoline, the 22 figure is per gallon of ethanol. But still.

Why would you ever calculate anything that way?
It's late, but I am trying real hard, and can see no practical application for that knowledge...

GM has actually calculated CAFE fuel economy this way for a long time, its the reason virtually all their SUV's are flex fuel and hardly any of their cars. Just google E85 CAFE loophole; but you're right, us normal folks wouldn't normally use this method of calculating fuel economy.
My last two fill ups my average mpg has gone from around 30 mpg, to 16 mpg!
I'm a conservative driver, and the weather has been cool, with little need for A/C. No difference in the way my car is running, or my daily driving habits or destinations. Checked the spark plugs, they look fine. Same old rough idle that the dealer never notices, but otherwise the car is operating as usual.
The 'Avg mpg' shown on the trip computer has been down from '34 mpg', to 22-26 mpg. But I'm getting 16 mpg!
I keep my receipts, have done the math both by hand, and track my fillups/mpg with 'Fuelly' and the aCar app on my phone.
All agree. My mileage has dropped by half.
Time for yet another unscheduled visit to my not-so-friendly Chevrolet dealership
