I have one question for the OP, was this done with the computer or by hand?

Computer. I done it by hand when I first got the car and both figures matched. Haven't compared recently though.

I don't trust the computer. Unless you get 32 mpg by hand I don't believe it.

+1 on that

Exactly, they confuse V8 cars with trucks and SUVs. I have a friend with an older V8 Lincoln and he gets mid-20's on the highway. He told me he can get as much as 27 mpg. I think it has 300 hp, too.

Not to say that all V8 cars get respectable gas mileage! I'm pretty sure the GT500 and new Challenger will probably use about 15% more gas than a Mustang GT.

the 32.3mpg figure sounds way too optimistic for an auto V-8.
If you have a tune and mods then I doubt the car's computer mpg readout is accurate, especially if you have non OEM rims.
Plus all that extra weight... I'm doubtful.

Of course going only 55 on cruise control, with no stopping will probably get you the best MPG there is. How many rpms does the V-8 do at 55?

I am able to get mileage figures similar to what the original poster claims with no problems. I don't care about people passing me. Their problem. I've also compared the figures I get by hand with what the computer gets and they are virtually the same.

I have a tune but no CAI. I can usually get about 28 MPG on the way to work if I set the cruise control to about 75 and this is the computer reading. This is close to what I calcualte, miles driven/gal used. I now also don't care about people passing me;however, once in a while I will let loose for a few seconds.
