Glad I found this thread...was just gonna start a new one to see if my MPGs are normal. Sounds like they are.

80% highway driving - 25 MPG.

I was hoping it'd be a little better. Our 01 Regal GS used to pull 30-32 MPG out of highway driving. The Bonnevilles we owned were always better too. Why do the L67s in the GPs net lower MPGs than in the Regals, PAUs, Bonnevilles, etc.?

gearing?

gearing?

Don't all L67s have 2:93 gearing? AFAIK, they do.

I thought that they did in the GP's, but I did not know in the bonne's or the Buicks....

I get about 20-22 locally. Don't really get on the expressway much.

My stock 04 gets about 19 in town and 27 on the highway, but my GTI get's 26/35 and 19 when the cruise control is set at 130 mph, hehe. Not bad for both my cars.

hmm.... 20MPG highway......something must not be right I drive 100 mile round trip (mostly interstate) to work each day, and am filling up 15 gallons at about 300 miles... sucks. FWI dropped it down from 22, but from what I'm see here, that still sucks compared to the rest of you. Only 64,000 mile on it too.

I read a couple threads on replacing the front o2 sensor, and that should help, I just wish there was a way to check it before throwing parts at it.....

Thanks in advance for the help!

My average MPG gauge reads 15.4mpg. When I bought the car is was at 22mpg, then a rod bearing and **** went out. God the rod, rod bearings, gaskets and seal replaced..and my MPG dropped to 18mpg. When a welding busted from my U-Bend to my resonator, it dropped to 14-15mpg.. fixed that problem, and it's still running around average 15.4mpg.. almost seems like when the rod bearings were damaged, rod and piston bent..it was getting better gas mileage...

Things I've done after that expensive engine maintenance, new Fuel Filter and Performance Quaker State Full Synthetic motor oil, fixed exhaust leak...

Hell I was getting better mileage on 91+ Octane..lol
