John,
After hearing about the great deals at Wal-mart for Mobil 1 synthetic, I decided I would find the location of a Wal-mart. I called 411 and found a wal-mart in a nearby city and went over to it. To my dismay, there was no Mobil 1 synthetic! They had TONS of Mobil 1 regular, but no synthetic. Grr, I was pissed, I drove 20 miles and they didn't have any! So I went to a pep boys and got the Mobil 1 synthetic (8 qts) for $4.49 each. Oh well... life goes on.... I just put the receipt into "accts payable" anyway. (BTW, I get 1/2 the cost of what I buy back.)



----oh and sorry i couldn't contribute about the amsoil----
