I dunno if an AP1 would last 60k without adding any oil. Oil consumption would kill it.

 

20K is the normal oil change interval on a 3 series BMW. They use a special oil filter and special synthetic oil. That's why it costs $150 for a BMW oil change.

I suspect they may have used the wrong oil or filter. The computer determines when to change the oil based on milage and stuff.

I sense we aren't being told the whole story.

 

i wonder how jacked up the cams are on that car... must be like the surface of a golf ball

 

pretty nasty

 

I agree that the computer probably notified the owner, but I feel it was probably just a lack of igorance on their part as well. I cannot believe the owner actually waited till 60k to finallly decide to change it. Unbelievable.

 

Good god how much oil did she put in there?

 

i know somebody made it to 30k on a corolla with no oil change

since BMW cost much more, 60k is the least i expected ... LOL

 

the best thing to do, to at least salvage the engine, take 1/3 diesel 2/3 mobil 1 fill that sucker up run it for about 15-20 minutes at idle watching it very very closely, after the time is up shut it down and drop the oil pan and pull the oil filter and the valve cover as soon as possible clean out all the gunk
after fill it with fresh mobil 1, run it for 100 miles and change the oil again, repeat every 500 miles after that until it's clean

 

This guy is going to spend more money on oil changes in the next 1000 miles trying to fix the sludge problem than if he had just done the changes in the first place.

I'd pull the engine and tear it down, clean, re-lubricate, and re-install. There is no way you will get all the sludge out without causing further wear and damage to the engine by running solvents and degreasers through it.

 

I like how they are talking about whether or not the oil that they will use with the cleaner meets BMW specs. As if it matters at this point. You could probably put Wesson Oil in there and have more protection than he has had for the last 60,000 miles.
