    I have a 2007 Suburban, with roughly 52,000 miles on it. It is using about 1 quart to 1.5 quarts of oil every 3000 miles. Seems high. No visible leaks, and it does not smoke at start-up. Any ideas? Thanks in advance for the help.

    While we may not like it, a quart per 3000 is regarded as normal by the auto makers...

    X2.. If you step up a level in viscosity that might cut down on consuption..

    Thanks for the help. I also have a 1995 Imapala with 120Kmiles that does not loose this much.

    I've read that some vehicles are not driven enough to boil off the contaminants & water vapor so during a normal oil change interval they don't appear to use/flash off any oil when they are simply replacing it w/ water and contaminants.

    If you always let the engine get up to operating temps and don't drive all short hops like some soccer mom you should notice some consumption. Like noted above, the manufacturers have done a bunch of things to increase the CAFE mileage averages. When they all switched to 5W-30 from 10W-30 oils it was just for that reason...
