DennisZ Posted March 30 Share Posted March 30 The last time I had the oil changed in my coach, I remember them putting in 28 quarts of oil. My owners manual say it should be 24 quarts. I was checking all my levels in preparation for an upcoming trip, and found the oil level high. I had noticed there appears to be a fitting that the dipstick is attached to and it moves in and out of the dipstick tube, I measured the level with it pushed all the way in, which would give me the highest reading. I’ve driven the coach several thousand miles like this and haven’t seen any adverse issues. Whats y’alls thoughts on this, should I leave it alone or drain some out? Thanks, Dennis Link to comment Share on other sites More sharing options...
klcdenver Posted March 30 Share Posted March 30 I wouldn’t worry about since you have driven it several thousand miles that way. I think you are suppose to check the oil level with the tube pushed in. It pulls out to make it easier to fill. Link to comment Share on other sites More sharing options...
cbr046 Posted March 30 Share Posted March 30 How far over the full mark are you? The hash mark (min->max) represents about 1 gal of oil. - bob Link to comment Share on other sites More sharing options...
DennisZ Posted March 30 Author Share Posted March 30 Looks like 2 to 4 quarts, need to go back and look closer. Link to comment Share on other sites More sharing options...

96 EVO Posted March 31 Share Posted March 31 My 'theory' is overfilled oil pan fouls the crankcase breather filter. When I replaced mine at about 52,000mi, it was very clean. Others have pulled theirs out dripping in oil, with 'check engine lamps' on for high crankcase pressure. This is just 'my' theory for why this happens to some. 1 Link to comment Share on other sites More sharing options...
DennisZ Posted April 1 Author Share Posted April 1 Went out today to get the real “overfill”, marked the dipstick level then wiped it clean to see the level makings, it’s about 1/2” above the full mark, my guess is about 1 1/2 qts over, if the dipstick is accurate.
