^I agree. I use a higher full temp weight oil on all of my bimmers (20w50 on most, 10w40 on the X). I do live in TX though, so take that into account.

Seems like "high" oil consumption though to me. My 4.8is ate 1qt after ~1500 miles during my Florida vaca trip, but I have bad valve stem seals so I was expecting it to do so. I don't recall any of my M54 3.0 equipped vehicles doing more than 1 qt. per oil change (~6000 miles).
