Thanks! I changed the oil last week (it was the first warm weekend I was free). Mann filter and Mobil 1 synthetic. There is no visible oil leaks and no gunk in the tail pipe. I thought the foam was related to water and the winter was harsh and I did not go anywhere. I just did a nice long road trip from West Michigan to NYC and I made it in about 10 hours, so I got the speed thing covered... Thanks for the input, in puts me at ease a bit. Just rolling over to 80K soon and want 80K more...
