Pontiac life span

i have a 2002 pontiac boniville that has `120 thousand miles on it . i was wondering how long i could expect to drive it. and how to keep it running as long as possiable becides regular oil change and fuel injector cleaner.


  • Investigate changes in sound or performance: don't let little problems become big ones.
    Follow the Maintenance Schedule in the Owner's Manual.
    Don't waste money on things like "induction service" or various flushes, however:
    Change all fluids periodically. I recommend:
    Transmission fluid: drain and refill every 30K miles, change the filter (if applicable). Use only what Pontiac specifies, no "universal" stuff.
    Brake fluid: change (bleed) every 3 years.
    Coolant: change every 5 years; change the thermostat and radiator cap.
    Power steering fluid: drain and refill the reservoir every year or two; an easy DIY job.
  • You should have no problem exceeding 200K with your Bonnevile. I say this mainly because it has the 3.8 engine which is pretty much bulletproof. Just keep up all scheduled maintenance and the Pontiac will be around for years to come. Make sure the transmission is maintained as well.

    My nephew still has the 1988 Bonneville that my wife and I gave him several years ago. We got it when my mother-in-law bought a new car over 10 years ago. He keeps it maintained and it's past the 250K mark and going strong. As far as I know it's only had a new alternator and water pump replaced on the engine.

    In my local shoppping center there is a lady who decorates cakes (known as the "cake lady") who drives a 1980 Pontiac Bonneville with nearly 300,000 miles on it. Her husband maintains it well, but does not go to extraordinary lengths to do so. Every weekend they take it out on a long enough trip to thoroughly warm it up and blow out the cobwebs.

    So I think you have many years of happy motoring ahead of you. Don't worry about parts in this case. Those GM cars were cookie cutter badge-engineered copies of each other. And wrecking yards will have enough body and trim parts.
  • I dunno, I got 530,000 out of my Buick that is largely the same car. Anymore it really isn't how long they last but how long you want to put up with them and spend the upkeep money.

    Do Pontiacs have a problem with fuel injectors?

    They are usually a non maintenance item....unless you go to those fast oil change places who sell unsuspecting people those type of services.

    Back to the orig question....Follow your owners manual as to what maintenance should be preformed and when. Drive it til the wheels fall off.
  • Use a premium synthetic oil in the engine. By this I mean one that meets the European specs for Audi, VW, Mercedes, BMW, etc. Just get the proper weight such as 5W30 and make sure it meets those specs and you should be just fine. As other suggest, don't neglect the transmission fluid.
  • I have a 2003. It's in the shop now and they can't figure out what's wrong with it. I feel kind of betrayed! I'm the only owner, always pampered it, gave it proper maintainence, fixed everything promptly etc....I planned on driving it 20 years! I guess some things just can't be fixed and you just never know...
  • @Jenetix - click on the 'New Discussion' button (top right) and tell us what the problem is, maybe somebody here can help.
  • Yep, the first step in any repair or problem resolution is identification of the problem. If you can't get that step done, not much can happen.
  • I've got a couple of friends with this type car. One owner got 300,000 miles on a supercharged 3800 engine and gave it to his college age son. The transmission was rebuilt once at about 225,000 miles but very little else except preventative maintenance. The others have between 150,000 to 250,000 miles.
