I went on a road trip to San Antonio, Saturday. I drove the 1,050 miles straight. On the second tank of gas I noticed I was getting excellent mileage doing 75-85 mph (about 3K RPM). I was at 250 miles just before the 1/2 tank mark. I toyed with the idea to see if I could get 500 out of the tank. I chickened out at 445 miles to the tank. All in all I found out that the more I drove the better the gas mileage, at least on the interstate. I hope this helps out anyone out there thinking of using their crossfire for a road trip.

 

So what was the MPG?

 

I believe that we have a 12 gallon tank...right?

 

it has a 15.85 gal tank.

 

The best I have gotten is 29.6 running 70 on the highway. I was pretty pleased, but still wanted to hit the 30 mark. Normally I get 27 - 28 just going back and forth to work, with most of it being highway speeds not exceeding 60 to 65. No complaints at all, especially when you throw in the fun factor!!

 

i'm also seeing about 27 mpg, driving back and forth to work, but i don't just stick to 60-65. i feel that i can hit the magical 30 mpg on straight high way travel. i can't do much stop and go running without getting heavy footed.

 

Burned off my 1st tank two weeks ago, from full to the warning light was 532 km, (532 -/ 1.6 ) = 333 miles, divided by 14 (allowing for reserve) = 23 mpg.
I have been GIVING it.

 

This about what I get driving to work and home, but on interstate I'm also doing about 450 - 460 miles on a full tank. I don't think I've ever put more than 13.5 gallons when empty.

 

I guess I had better get my car tuned or keep my foot off of the accelerator. I'm lucky if I get 20 mpg. I will check the other crossfire this week.

 

I have a lead foot myself. Don't forget the SRT-6 is rated about 2 miles less per gallon.

 

I wish i were getting 2 miles less per gallon. Lets see 29 minus 2 equals??? Where's my ... not enough toes and fingers.

 

I get about 23 MPG daily driving. The higher mileage is on longer highway trips.

 

The SRT6 is rated for 17-24 miles per gallon. Rmaderman, you are doing fine.

The best i got was 24.5 miles/gallon (SRT6).

 

I only have 500 miles on my xfire and just calculated the MPG @ 19 (17 mile stop and go commute). I was happy with the 19 MPG as compared to the 9.5 MPG I get with my H2! I was a bit disappointed as I was hoping to get around 25. Maybe the MPG will get better as the engine breaks in.

 

From my experience, it won't.

 

Ditto. Almost all my driving is done around town with frequent starts and stops at traffic lights and I average 20 mpg and rarely do much better under these driving circumstances. There's a definite improvement on the highway but I've never taken a long enough trip to get a good read on highway mileage.

 

Right now we're in Summer blend fuel season, it just started about a month ago. I was getting 22 max. MPG last month, now it's just barely making 18 mpg.

I did replace my air filters and no change either. If you could bolt on some lighter weight rims that could help your fuel cost over the lifetime of the car.

 

I keep a maintenance log that includes mileage, computed the old fashioned way (miles driven/gallons). Over 22k miles, mostly highway driving between Holland and Detroit or Midland, I average 27 mpg at 70-80 mph. I once achieved 31 mpg when I drove to Midland at 55-65 mph. Another time, coming back from Detroit with a government car acting as bear-bait, I drove 80-90 (hitting 100+ a couple times) and still got 25-26 mpg. Best on a tank of gas was a little over 400 miles on a round trip to Detroit.

I have the 6-speed, start coasting when a light turns red ahead of me, and generally shift at lower rpms (under 2,500). I have the bad habit of driving fast rather than accelerating fast.

Even around town I get over 20 mpg.

 

I noticed that you have an Audi A6 in your signature, what kinda mileage do you get in that car? I know it's a lot heavier than the XF.

 

Seriously...I don't care!!! Put the pedal down and drive!!!
