gas mileage

**kenizzle36** · 06-29-2011

Ok I must be doing something wrong. My GT is only getting on average 22 or less.

With a lot of highway driving.

'05 GTP currently getting about 28 on the DIC, 90%+ highway. I've noticed that its really sensitive to fuel quality, as it can drop by 2mpg or more if I switch from my usual gas station.

When I drove to Tennessee at the beginning of March, i got an avg of 31mpg all the way down. I was really impressed and it was the first road trip in my car since owning it and put that rebuilt engine to the test

11 in town, 22-23 highway.

98 gt coupe.. Completely stock, 101k and I get 17 city and 27+ highway. On the first road trip in this car last summer I got 30 mpg with 4 adults and a trunk full of camping gear

Ah, ye of little faith... My LS4 is a bit different than GM's idea of it.

And I drive about 4 miles a day. So 11 is pretty good.

I'd like to see a proper LSX instead of this Al block nonsense.

Al blocks transfer too much heat to the tranny, cooks 'em.

As if they weren't weak enough already.

I never said anything about a 4T65...

My 2 door GTP I can get about 24-26 city. I went on a 3 hour road trip a few weeks ago and i got like 29 on the highway. I need a tune up and beat the S**T out of it way too much. About half of all my driving is on the highway though.

I tend to get 23mpg when cannonballing across the country at average speeds of 85 with stops. I'll let you guys fill in the blanks as to what the low/highs are on that.

**dmahlikGT** · 07-01-2011

Based on my quick head-math skills im getting roughly 18-20 city with a semi heavy foot, i rarely do highway driving but i ve done a straight 60-70mph before and my gas needle barley moved for a while.But now i get roughly 300 miles to a tank.Mods do help too cuz when i was stock i would get 250-280 consistently, now 280-300 all the time.

Well I took it on its first road trip since fixing my burned o2 sensor after my header install. I had to go fix my sisters car which is roughy 90 miles away and I doing about 65-70 like the whole way I got 27-29 prolly. I didnt use a calc to be exact, but its close to that.
