| Re: I averaged 31 MPG in my STS V8!
I picked up an off-lease '05 STS4 a couple of months ago. It has about 43K miles on it with new tires. It's going on its 1st long highway trip (~700 miles) next week. I'll report back on the mileage.
So far my across town 12-mile commute has yielded about 16mpg.
BTW-Thanks to everyone on this forum for all of the good advice on TSBs. Your info helped me to get the tranny reprogrammed, the driver's door handle fixed, and the wiggly seats solidified!! Although I think the tranny will also need the TCC replaced.
Good thing it's CPO and covered to 100K miles! |
