My daughter’s car has been using a lot of oil lately. 2 to 3 quarts a week. We had a friend check underneath for any leaks and he couldn't find any. It doesn't smoke at all.

Any ideas what I can look for?

Thanks, Brenda

See if the air filter is saturated with oil, if so then check the PCV system for blockage. It's gotta be going somewhere.

that's A LOT of oil fro acar that only holds 4 quarts. Even if it were burning that much through PCV it would certainly smoke. I agree that much oil is not just burning off normally.
