This is what I've heard... but Amsoil is pretty expensive, and this guy I know has been selling Amsoil products for years. I dunno if this is something they just told him to tell his customers, but I'll ask him for some documentation if he can provide it. It does seem pretty hard to believe that you could create it without some kinda petroleum or natural gas, tho.Also, as far as I know, EVERY fully synthetic oil is manufactured using standard petroleum as a feedstock.
That being said, the oil is broken down into the basic hydrocarbon chains, then reassembled to the final molecule length.
Although it's probably possible that a synthetic oil could be produced using coal as a base, it would be much more expensive to produce.
I've heard of Castor Oil- not the choice for me, but which pre-mix oil brand would be the best choice?
Any recommendations would be greatly appreciated! Thanks!
