Just came back from a cruise, thought I'd check the oil. down about 1qt.only have 800 miles on this oil change. first oil change at 450 miles, was down around 1/2 to 1 qt. second change at 3400 was down 1 1/2 qts. right now I'm at 4250. looks like I mite have ring stuck or it's just eating the oil to brake in . all my other cars never used this much. anybody having the same problem ?
