Hi All,

This is my own car. I bought it brand new. It just turned 74,000 miles and it has been taken care of exclusively by me. The oil has been changed every 90 days since new--sometimes it had 1500 miles on it and other times 2000 miles, but never more than that between oil changes. My problem is, it seems like exhaust is getting into the oil. I changed the oil back in September, and just happened to check it in the middle of November--there was 1700 miles on the oil--it was jet black--so black that you couldn't see through it to read the stampings on the dipstick. I immediately changed the oil again, and now, with 300 miles on it, the oil is jet black again, and the dipstick smells like exhaust. The pcv system is working fine, and there is no blowby and no moisture in the oil. It runs like a top, but the oil seems to be getting exhaust in it. How on earth can exhaust be getting into the oil with no other symptoms--no miss, no noise, no nothing---I'm stumped !!!
