I just picked up 12 quarts of mobil 1 0w 30 for 2 dollars a quart and 12 quarts shell rotella synthetic 5w 40 for 1.50 a quart a wall mart. I am going to do 7500 mile drain intervals (highway) with them both. Hope the 0w 30 holds up good.
Excellent price!!! I have 3 Wal-Marts in my local area and only one of them had the sale prices. They have discontinued both the Shell Rotella 5/40 and the M-1 0W30 so they had the gallons of Shell for $5.00 and the quarts for $1.50. They were charging $1.50 for the M-1 0/30 also. I declined the purchase of the M-1 because it isn't a fluid that I'd ever use but I did buy a few gallons of the Shell Rotella 5/40.
