Black Oil??

I seem to be having this problem with my car from the day i bought it. my oil does not last long at all whenever i change my oil it only stays clean for about 2000 kms or about 1200 miles. I have tried comercial products such as seafoam and lucas oil and they seem to help extend its life a little bit. im thinking it could be my valve seals but i dont want to jump into a task like that without knowing for sure that is my problem. the car has now 186000 kms (115000 miles) i only use synthetic oils with a fram oil filter. Any help at all would be much appreciated.

Re: Black Oil??

The oil's supposed to darken as it cycles through the engine. The color change is a combination of heat slowly breaking down the oil and additives, and contaminants too small for the filter to strain out. If you're worried about how long the oil is doing what it's supposed to do, there are commercial labs that analyze samples for a small fee -- plug "oil analysis service" into your search engine. That'll tell you if the oil's breaking down too fast, or is picking more than the expected amount of contamination from the engine.

Changing the valve seals won't make the oil less used...it'll just prevent oil from leaking through the seals, if they'll actually leaking.

Re: Black Oil??

I change my oil every 10,000km. It gets a little dark, fresh filters and a magnetic drain plug help, but it will always go darker with use, for the reasons the above mentioned.
