Well the tranny service should be done every 30,000-40,000 miles and the tune up like plugs and and plug wires about every 30,000 miles.

My chevy has about 98000 miles. When is tune up recommended.what is involved in the tune up?

what engine? The fuel filter is in the fuel tank, Spark plugs should be replaced, throttle body cleaned, and the truck generally checked over, battery , belts, brakes, tires ect. Spark plugs, trans fluid, filter, transfer case fluid change, are all due at 100k. You should have the 100K service done. Of course they base that on if you have been following the service schedule. Your owners manual will list all things that are due.

I have 101,000 miles on my Trailblazer and the last time I had an oil change they wanted to put in synthetic oil......nothing in the owners manual about doing this......should I change or keep using the...

its mostly personal preferance.. your trailblazer doesnt call for synthetic so if you dont want to spend the extra cash i would just get a decent brand 5w30 or 10w30

I have 103,500 miles on my 2002 nissan sentra when should I change the timing chain

The timing chain doesn't really have a maintenance period. They don't have a habit of breaking or stretching. Timing belts on some vehicles do have a recomended replacement period. Locate your local NTB, Firestone, or Sears for the maintenance schedule.

2002 Chevy Trailblazer LT Oil Pressure fluctuates.

Hello. Those oil pressure readings are completely normal for you vehicle. Actually, in a vehicle with that amount of miles, those readings are quite good. It's normal for the oil pressure to rise and fall with engine speed. Keep doing those regular oil changes and you should get many more miles out of that engine.

Yesterday i asked what parts i would need to complete a 100k tuneup on a 2000 montero sport. the answer i received directed me to a website which required a logon and password. Can anybody just give me the...

You can get your complete schedule here at the mitsubishi website: http://www.mitsubishicars.com/MMNA/jsp/owners/regular.do which includes all of the parts and when they should be replaced. If you have not followed the schedule, you will need to replace the following:
-oil and filter
-air cleaner
-spark plugs
-ignition wires

That is for a basic tune-up. Refer to the link above, with a pdf link included on that page for a download of a recommended service schedule.

If this was helpful to you, please rate my answer. Thanks, Rolanddirty

My oil light with a little wrench beside it came on this morning, I have a 2007 chevy trailblazer and I just had a oil change 1 month ago

If the service light is on in your TrailBlazer, open the door, turn the key to ignition position and push the accelerator pedal 5 times, the service light will flash. flash your high beams and you're done.
