Replying to: fenster (Feb 08, 2008 8:04 am) I expect to enjoy The Blue Max for many more miles. You should consider a preemptive replacement of the original radiator and expansion tank as these are known issues on E39s. If it's an Automatic as most 528s are, don't rely on BMW's ludicrous Lifetime Lube scheme, have it flushed every 60K or so. If that hasn't been done on the one you're looking at, or isn't documented-- beware! Shifty's advice about preventive maintenence is right on. |

I have a 2001 530I with 98k miles. I had the oil changed in mid-December. Two weeks later, oil light came on; oil level was several quarts low. Oil droplets were on the rear end of the car (I did not notice early on because the rear end was covered with snow). Oil dripping from tailpipe. Mechanic was puzzled, replaced oil separator. No change. Help...

Replying to: Mr_Shiftright (Feb 09, 2008 11:57 am) With its replacement, at least in the short term, the problem with my 530i is not solved. Possibly, the new, finer synthetic oil with the recent oil change? Or, earlier threads on this page suggest new valve stems/guides? Advice?

Replying to: beolson (Feb 10, 2008 12:14 am) Do you get a puff of blue smoke when you first start the car in the morning? Actually I think you need to start a very careful oil consumption test to see what's really going on here. This would require placing the car in a level spot overnight and in the morning marking the dip stick level, then driving 1,000 miles and rechecking at the same spot in the morning before starting the car and marking the new level.

Replying to: Mr_Shiftright (Feb 10, 2008 2:28 pm) One last question, this excessive oil consumption began to occur immediately after I had the oil changed in December. Coincidence? From item number 434 on this page, "The main reason that you wouldn't want to switch is that the engine seals will have shrunk on a higher mileage car and synthetic can leak because it's much finer." Not sure if they used a different brand or weight range? Again thanks for the feedback.
