Nice thread.
Ok then AA Castor is the best and to always use it.
EDIT: Sorry about this off subject question but all the right people seem to be here to ask.
What about the synthetic oil? I heard that a good test is to put about an ounce of mixed fuel in tin can or something. Light it on fire, and that the fuel mixed with the good grade synthetic will burn blueish and you should have a perfectly clear clean oil remaining at the bottom when the fire goes out. BAD synthetic oil will leave a dark nasty residue that looks like burned coffee beans, and the fire will be yellowish.
Anyone ever try this?
