    My manual says Your vehicle has a computer system that lets you know
    when to change the engine oil and filter. This is based on
    engine revolutions and engine temperature, and not on
    mileage. Based on driving conditions, the mileage at
    which an oil change will be indicated can vary

OnStar always emails me when it's time. They tell me what % of oil life is left every month, along with how many air minutes I have remaining, etc. I can usually go about 10k miles between changes.

Follow the owners manual, usually 3 to 5 thousand miles, oil does not go bad but it absorbs contaminants, and can only do so much, also check any filters

Why will my 2008 hummer H3 door locks with key but will not unlock with key. the key will not turn to unlock

The lock assembly in the door is faulty. It gets tricky since Hummers are no longer in production. Changing the door lock cylinders will get you a different key than the ignition. Any GM dealer should be able to get you the parts.

What would cause a H3 Hummer to burn oil and give off smell. Temperature gauge rises as well.

One thing that could do all of that is a blown head gasket. That would allow the oil to mix with the coolant and the coolant to mix with the engine oil. Have to get it fixed right away or the engine will be trash.

My 2008 H3 hummer seems to being oil. My service temp light comes on and temperature gage starts to rise. It also is giving off smell like burning rubber and at times smells like rotten eggs. What wou

Rotten egg smell is your cateladic converter... part of your exhaust pipe... should go away in a month.... the smoke coming from your oil is natural... as the oil heats up it can smoke a little... kind of a wisp... anymore then that you should get it checked.... park the rig on a large white sheet and check in a day for oil spots, if you see some isolate the area, a lot of times it can come from a loose oil filter, or oil plug but some times it comes from a worn seal. also check that the pvc valve isn't worn.... then if they are all ok I would be thinking the engine is burning it is important to use the right weight of oil for the temperature... too thin burns off, too thick over works the oil pump and rings on the piston. stay away from the cleaners unless you are changing the oil, I use a product called sea foam personally. Good luck

Problems with hummers

There is virtually no difference between the Hummer H3 drive train and comparable GMC and Chevrolet drive trains. Although you overspent on a piece of pseudo-military jewelry, the drive train is reasonably reliable and easy to service, and parts interchange with GM truck parts.
My sole recommendation would be to use 15W-40 diesel-grade oil instead of the recommended oil and, if you haven't already done it in the last 20,000 miles, change all fluids (crankcase oil, brake fluid, transmission fluid, differential fluid, power steering fluid, engine coolant).

Hummer h3 I'l change me manuel Transmission Oil

There is a threaded plug on the bottom of the transmission that is 1/2" drive take this out and the fluid will drain, replace and on the side there is another 1/2" drive plug that you use to fill, you will fill until the fluid starts to come out this side hole. Hope that helps you.
