The car is OBDI, I'm not sure if there are any instruments out there for cars this old. I just compute by hand; fill the tank, record mileage when filled, compare miles at next fill up and how many gallons to top it off then compute miles per gallon. I think the EPA estimate was around 23 mpg highway if I remember correctly. I'm just slightly beating that. However, I can very easily beat the EPA rating on my wife's 2007 Toyota Corolla (auto trans) with no problem. It's rated at 34 mpg highway and I've consistently been able to achieve 42 mpg and higher on rare occasions.
My Lumina just doesn't seem to be able to do any better than 24 mpg and I'm wondering why. I'd think I should be able to achieve upper 20's mpg without too much effort, but I can't.
