I was on a 340mi trip the other day and i lost 1 qt of oil at about 250 mi into the trip, then after refilling 1 qt on my return, the light came on again and show another qt loss.

there is NO LEAK whatsoever. I know there was an issue earlier with this as bypass, its not burning it as I have no indication of smoke or residue on the rear end.

Its a 2000 ml320 with 82k miles. What can I do that doesnt cost a ton and will the dealer still honor anything regarding this issue?

Thanks,
