    Re: Any good cadillac mechanics in chi-town?

    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.

    EDIT: 2001 STS:

    City = 10 - 14 mpg
    Suburban/near rural = 15 - 19 mpg
    Open road, 70 mph = 24 - 25.5 mpg

    on 87 octane, the recommended fuel. Run a Top Tier gasoline.

    Thank you fellas! Current codes are as follows:

    C1246
    P1860

    RFA: C0750, C0755, C0760, C0765

    I also replaced boots and plugs 2-3 months ago. Regular oil changes and I always make sure I'm topped off. I am pushing her a bit tho. I'm average 75mph on this trip.

    codes are meaningless without their DEFINITIONS -
    and no one has them all memorized -

    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.

    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.

    Re: Any good Cadillac mechanics in Chi-town?

    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.

    That makes a lot of sense. I have another trip coming up tomorrow so maybe I'll do it then. Thanks for the advice!

    Get a pair of the yellow Playtex HD rubber gloves - If you do the do the oil will be HOT !

    GM says - and I like to - prefill the filter. Exactly 7.5 quarts, with filter, brings the level to the proper marks on YOUR dipstick.

    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.
