What amazes me about Amsoil is that they do not market towards mom and pop that need to get thier Lincon Town cars oil changed. They market towards the after market crowd. I am not positive but do they even offer a non synthetic oil? So for them to turn the profit margins they do is pretty dang good, when you compair them to a Exxon that is pumping out hundreds of thousands of gallons of gas, diesel, and motor oils.
They have also entered the market of fertilizers I guess too.
