Just like keeping things local. As for corporate thing, Amelia and warren are independant. Corporations yes,but not the big greedy rockefeller and JP morgan like ones. So for me I saw fram synthetic and mag1..but he only carries the synthetic in 5w30,and I know its a Mich higher noack valatility. I really like the black of 10w30,s. Way less vapor loss.
So! For 22-27 degree temps,jan/Feb here...think fram synthetic 10w30 would be ok!? Or 9 year old Pennzoil ultra 10w30?
