AMSOIL's better than Mobil, Exxon, and Castrol synthetics.

A true story:

New Jersey, prior to WWI and WWII, was a great green place.  They needed
charcoal to help generate steel for the wars, so guess what - they cut down
all the trees in the state and used them to make charcoal.  Very few trees
in this state are > 75 years old, believe it or not.  Those that are tend
to be in the more metropolitan areas, where it wasn't economically feasible
to harvest them.

So, there is some reason for concern here.  (I have a similar story about
the trees in Germany during WWII, as related by my mother [who was German
back then]).

My grandfather used to work for them, prior to that it was Rocketdyne and
Reaction Motors.
