Everybody got a different answer.BUT dependant on oil burn i would reccomend a 10/40 semi synthetic,(going upto a 20/50 at 100k if using a pint every 1000miles.)then when oil burn gets too great, time for a rebuild.

SOURCE: motor oil type 1997 rodeo

If this Rodeo has the V6 engine, then there is a tech note on the Mitsubishi site. If you hear valve train clatter, then use synthetic 0W30. No valve train clatter then 5W30 synthetic. Heavier weight oils cannot properly lubricate the valve train. Mitsubishi later changed the design of this engine to address the issue.

I have a 2000 gmc 1500 pickup truck z71 what type of oil do I put in it.

Boy. Now you have opened a real can of worms. You will likely get many different answers, but the viscosity to use depends on the expected temperature where you will drive for the next several months. Use a quality multi-vis oil (Castrol, Valvoline, Kendal) and read owner's manual for basic recommendations. The milage on the engine affects your choice as well. I would use a 10-30 if engine has 100k to 200k, and perhaps 10-40 if in hot climates or engine has more wear.

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).

89 gmc c2500 5.7 tbi had oil changed at well known franchise place. They also recommended flush out, let run 15 min with stuff he put in oil. Then drained, added oil and was about 1/2 mile away when motor...

Hi, this is not the first time i've heard of this problem..I have repaired engines with rod knock, crank bearing knock and piston slap after these treatments. These products can clean so much carbon and varnish from the engine that it brings the real internal problems to the surface. Try using thicker oil

When do i change the oil in my 2008 yukon denali?

The question you are asking indicates you wanna know the ideal time to change the engine oil of your yukon.
The ideal time recommended by the manufacturer is after every 6months which is the time for the general servicing of the engine.
To achieve optimum perfomance of your car,it is recommended you carry out other actions,which includes the cleaning of the spark pluggs,oil filter and the fuel filter.

Excessive oil consumption. Some smoking when accelerating. No visiable external leaks. Any Idea? 1995 GMC Sierra 2500 5.7 L

excessive oil consumption and smoking is usually due to worn rings and/or valve guides in the engine. If you observe blue smoke coming out of the tailpipe, it signals a worn out engine.

If no external leaks, that's what it is. Maybe try to change the oil with a high mileage oil when changing the oil and filter.

I'm afraid, that these conditions don't get better with time.

A replacement motor, or overhaul of the present one is recommended if you cannot pass emissions tests in your area if required by law.

My 2005 canyon with 3.5 engine has rod and main bearing rattle when it is started first thing in the morning. the rest of the day it is ok. can you ancer this problem.

This bulletin cover the use of wrong oil filters on the engine. The use of GM oil filters is recommended on your truck.

What happens is the oil will go into the oil pan over night causing the engine knock in the morning. The GM oil filter has a check valve in it to hold the oil in the upper half of the engine.
