Just picked up our new TL and noticed that after driving only 30 miles, we've already gone through a quarter tank of gas. The trip computer says we're getting 11 mpg....is this normal?

I know cars get pretty bad mileage when new, so I'm really hoping that this improves as the car gets driven more.

 

1st tank is used to be worse case. Then, your car will run better after a few k miles, and this machine will show you his best on highway.

 

My first tank was all highway, I had gotten around 32mpg which I was pretty happy with.

After that, with a mix of 80% city, 20% highway, I was averaging 13 -15 mpg, this car does not like stop and go traffic for sure.

 

Same thing happened to me. Now I'm at 1,600 miles and my MID says 20 Avg MPG and my Ave MPH is 25.

95% of my driving is suburbs with lights. Never really get above 50 mph.

The car is simply awesome on the highway though. No doubt I'd get more like 30 mpg.

 

It's definitely crap, mine were about 80% highway miles and I think I averaged 17 or 18 mpg. I am working on my 2nd tank right now.

 

It is possible the dealer didn't completely fill the tank, so the needle might show 1/4 tank gone in only 30 miles.

If your car was started and stopped a few times at the dealer before you picked it up, and then you did the same, or drove in city traffic, this could be the reason for the 11mpg reading. It takes a while for the MID to accurately compute mpg.

You might try filling up the tank again and starting fresh. When the nozzle automatically shuts off, do not add additional fuel. Then, reset your MID and watch the mpg indicated. It will start out very low, maybe 6-10mpg, and then gradually rise to a more normal figure as you drive more miles.
