I've always thought that Amsoil stood for American Soil Products!

All lub and fuel oils originate from crude oil feed stocks, unless you are
using Wesson oil.  Refining processes and additives may differ among brands,
but the word "Synthetic" is what you pay an extra $5. per quart for.

I've always run what ever is on sale, as long as it meets API SH specs, and
change it at 10K intervals (+/- 2K) only because that interval is easy to
remember.  But I'm also an advocate of the never change oil philosphy.  Run
the car for 100K to 150K and trade up, recomending this to my son who is a
mechanical klutz.
