Thread: Post up your Average MPG

Before I chipped the piston I was getting ~18 city and ~33 highway driving on a untuned 3.4 setup. After the chipped I'm getting like ~14 city and 24 highway on a tuned 3.6 setup.

CAI hurts gas mileage?????

Usually it does because people drive it harder so that they can hear their engine more. Otherwise, it helps.

When I was NA (although I had the GT1 cam plus much more) I hard:

28mpg highway

Never checked city or combined.

Now on the CSC setup:

17 city (squealing the tires as much as possible and very hard driving)
25 highway (@75ish mph)

Does Ram Air affect L67 MPG?

My 00 GT got like 18mpg every time I checked it mostly all city but even with some hwy. My 98 gtp on the other hand averages 30mpg at 75 and city varies a LOT on how I drive it but if I try I can usually keep 24+ strictly city

I had no idea that the NA GP's get that kind of mileage, looks like most are at around 18 mpg....and I get and average of 19.7 in the city and 30 hwy with me romping on it at least 25% of the time. What gives? I would have thought at least 22-24 city on the NA's

imeant 30-32 because i have seen my mpg in that range, it depends on if there are hills to coast or not. i went to buffalo recently and had it at 32.1 when i got off the expressway. i usually drive like a granny lol i coast whenever possible

considering ram air wont even help make power...no.

2002 GT stock
During the winter months im getting about 16 mpg city and about 21 mpg 40% city / 60% highway. During the summer i usually get about 18 or 19 mpg for city driving.

N/a with a good tune and E85 19city 27-29 interstate

i get roughly 25 average. ~32 hwy/22 city.

the faster you go the less MPG's you should get and its cold outside, and that means even less mpg's.

and maybe do a full tune up.

i Average about 18MPG on the GTP and the GT comes in at abut 17MPG

Yeah, but it's not that, it feels like its going in and out of lock, the revs drop and raise, its not right

DOD?

Yes, but I read somewhere that it only makes about a 10% difference.
