Using oil between changes

[f5fstop]

Have the dealer run an oil usage test on the vehicle. They top off the oil, seal the stick and the drain plug and have you come back at different dates to have it checked.
If an engine has piston slap, it goes away when the engine warms and parts start to expand.

Checked the oil today and I am 1/2 quart low. I topped it off on wed. and after about 400mi this weekend I am low again. Tomorrow it goes into the dealer.

Good luck! I hope the dealer has a good tech. If not, this can get pretty ugly.

Have you looked to see if there is any oil traces on the block?

I have not noticed any oil traces on the block and I did drop the H3 at the dealer today. This sure sucks being without it , but they are going to call me tomorrow. But that doesn't mean anything.

Well I am now back in possession of my H3 . The dealer is running an oil consumption diagnosis, after 1500 mi I am to take it back in for a check. If there is no oil used in the 1st 1500 mi I am to return it at 3000 mi. Document ID # 1271371 2006 Hummer H3 states " Excessive oil consumption (not due to leaks) is the use of 0.95L (1.0qts) or more of engine oil within 2,414 kilometers (1,500 miles)

And if you look the oil pan has a seal on it (or should have) and the dipstick is also sealed (again, should be).
