Cadillac Seville / Cadillac Eldorado Forum Discussion, Any good Cadillac mechanics in Chi-town? in Past Cadillac Vehicle Discussion; Might be interested in replacing my TCC while in town. I'm getting HORRIBLE gas mileage!...
Do you have any TCC codes and does the converter lock up at road loads over 43 mph ? Quite a few factors figure into "gas mileage" - other than TCC, which should cost you about 1 - 2 mpg on the road and make nearly no difference in city/near suburban driving.
Anything from driving habits, engine mechanical and tune condition and normal maintenance (or lack thereof) will influence gas mileage - sometimes radically. (And NO snake oil on earth will make any difference UNLESS maybe a fuel injector(s) is stuck open [long shot].)
Look up Joe Blau at Midwest Cadillac Repair in Palatine - west of Chicago.

Re: Any good Cadillac mechanics in Chi-town?
Probably numerous "good Cadillac mechanics" in Chicago. I just don't have any personal knowledge of them. Lots of dealers here and one would assume that they have good mechanics, but I would agree on Joe. I know him personally and would also recommend him.
I am pushing her a bit tho. I'm average 75mph on this trip.
Pushing ???? Phooey !!!! The thing isn't even beginning to breathe hard. That car will run 24/7 at 115 mph and never break a sweat. The problem with many of them is they NEVER get a chance to RUN, and that's what kills them.
At the end of your return home - as soon as you turned off the key - was the absolute ideal time to change oil and filter. After a long high speed run - several hundred miles - the inside of the engine is squeaky clean and all the nasties are in suspension in the oil - it all drains out when the plug is pulled and the filter dropped.
Think about what cleans and cools all those bits and pieces of machinery spinning around in there .................
Let the car sit a day or so and all the microscopic particles and moisture/blowby acids settles to the bottom of the oil pan again.
Yep, they thought me that in school a few years back to prefill the filter. And I learned about overfilling these engines with oil a couple changes ago. I put in 8 and was leaking oil all over the place and couldn't figure out wth was going on until I found out the motor releases what's extra.
