I changed the oil on a 98 323i today. The customer had stated he had suspected the guy that he was taking his car to wasn't changing his oil....
Might I just say.... suspicions confirmed!
this stuff wasn't soft and jelly like it looks, it was hard as hell, kind of waxy.
this car rocks synthetic oil, so for those of you who kinda slide on maintenance, this is what happens!
thank god for oil bypass valves, otherwise, his motor would be totally toasted.
the first picture is what a normal filter looks like clean, its a different brand, so the end cap is different, but the medium is the same.
