Just kind of curious why you would switch. I know about the claims of
synthetics, but when I read about people whose vans go 150K miles on
dino oil, and they don't leak any oil, or have any OP problems, I tend
to think, wow, whatever they were using all those  years, sure seems to
have done a great job, and  yet folks want to double the cost of their
oil, to replace something that hasn't given any indication that it has
failed to do the job....

I often marvel at the 'high  mileage' oil commercials, and can only
think that if what you are using, got you all the way to the high
mileage mark, why would anyone want to stop using what got you there?

Just wondering about the thinking behind the change, not wishing an oil
war, since we already have one of those :-)
