Roger, I think you've got a little extra in your oil description. Mobil 1 Delvac is 5w40 synthetic oil. Mobil Delvac (no 1) is 15w40 conventional oil. I think you mean the latter. If you were changing the former at 3K you were wasting oil for no reason. In a 61x engine I never went over 8,000 miles, the soot levels would force a change. Thats why I ran conventional oil in the summer time. In the winter I needed the superior cold starts synthetic gave me so I used synthetic and changed at 8k. I don't miss changing oil in the winter time. Both VWs are getting due for a change, I'll have an oil change party in October and do both. We're not driving as much as we used to this should last me a year. Actually the Jetta I'll probably be early on but I don't want to do it in February... -Curt

I've used Mobil 1 Delvac 15x40 in my two old 617s for around 20 years. Neither one has had the head off nor any engine problems. One has around 425,000 miles and the other around 360,000 miles. I tried the other oils at first (Delo, Shell, etc.), but Delvac kept the oil pressure slightly higher when hot, was fine in the Winter (although I live in the Atlanta area, but have seen some cold), and really keeps the soot and dirt in circulation so it all drains out at the oil change. I always encourage people to use what works for them. I'm just passing on what has worked for years for me. And yes I used to drive a lot so I changed oil every 3K and that was sometimes every 1.5-2 months. Best Wishes, Roger Roger Hale Dinnerware Classics, Inc.
