Bought some from the local dealer here named Lowell Schimek @ 520-573-3696. Cool guy and he sells at wholesale prices so for a little more than Mobil 1 you can get some Amsoil. Haven't changed the oil yet, waiting until after I go to Wake the Devil and changing it.

 

I get mine through archie at psi. its been a while but i believe im paying $10 a quart. whic i believe is average

 

This Lowell guy sells it for much cheaper. <$7 for 0w30.
