Hey guys! I just got my G on Friday! It's been a great weekend taking it out and driving it around and I already have about 150 miles or so on it. However, the fuel economy seems to be pretty bad. I average a 13 mpg. Now is this because of the engine being new and it will improve after I break it in? Or is it a defect in the car? I'd appreciate any help. Thanks!

 

it's because you are gas happy



i get exactly 19 and my car is supercharged!

i am not so sure..i have 500 miles on my car now...and i am getting about 15mpg.....i drive pretty conservatively...

 

Wait till it breaks in. When I first got my car, I got 12 mpg, then at about 1200 miles, I was getting 16 mpg, now at about 2500 miles, I'm getting 19 mpg....I'm hoping to get to about 20-21 mpg.

i get about 18 mpg in my daily commute, and a best of 25 mpg on sustained highway driving at 80 mph.

12,000 miles on our car. My wife and I just returned from a Labor Day weekend trip. Lots of highway driving, most of it way over 80 MPH, fair amount of tootling around at 25 -> 50 MPH, and we still got 22 MPG.

Try a tankful of highway driving at reasonable speeds : 65-80 MPH. Most get 21-27 MPH.

Hugely powerful yet with a liquid cat-like elegance. The car has it too.

i agree with the above. I have 12000 miles on my 6 speed and get 25 and change according to the nav at 82mph. Just have a z tube, k&n panel filter, and mobil1.

 

I just hit the 1200 mile break-in point on my new Coupe on Sunday. My mileage averaged 20.18 MPG and that was about 40/60% city/hwy miles. The freeway miles were at speeds of about 75-80 MPH also. I'm pleased so far.

 

Hey, I'm at about 190 miles now, and still running about 12-13 mpg. Friend says I should check it out as there might be a problem in the compression. Is it normal to have that low of a mileage during break-in period? Or should I really check it out?

 

I just went over 200 miles and I'm averaging about 15mpg, it gets better the more the engine breaks in.

 

Try a different pair of shoes. Some shoes are known to have lead weights in them....LOL Mine was the same way. It will get better. I have 1500 miles now and I get around 20mpg on mixed driving.

I get 22mpg.

I think you're getting 13mpg's because you probably live where it's quite "hilly". Umm... SF?

Buy a Geo Metro or move. j/k

Try skipping gears. eg. 1st-3rd-5th-6th or 1,2,4,6.
Shift under 3k.
