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...

Subject: Re: [MBZ] Q for Larry
I'll add my usual different opinion on oil. 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
