psfred on 4-20-04 (88 300 sel question)mentioned that significant loss of oil can occur from the oil filler cap. Do others agree and is there a way to check the cap? In the same link someone reported that we should keep are oil level between the marks-not at the upper end. Stu Ritter said something similar in the Mercedes Club Mag-does everyone agree with this? If so my oil level light will intermittently come on at this level. I have ordered a new sender already.
