I know this is like which ice cream flavor is best, but after investing mucho
bucks into a new engine, wondering if anyone has any ideas on which oils might
serve me best. I live in Michigan where it gets plenty cold and also plenty
hot in the summer. In the past I have run 40w in the summer and 30w in the
winter. I have been thinking about switching to Mobil One 15W50 since I have a
new engine to deal with after it is broke in. My husband is trying to get me
to switch to Shell Rotella 15W40 which he uses in our other 3 VW cars. Any
ideas would be appreciated, I am sure this has been discussed before my
arrival to this forum, but I cant seem to get into the archives from AOL.
Thanks for your ideas...Cathy..87 Vanagon GL, 86 Jetta Diesel, 85 Golf, and 95
