For those of you that use synthetic, Wally World (Walmart) has Mobil 1 in 5 quart jugs on sale for $17.88. That's about a $1 a quart less than regular prices. I bought 4 jugs, and I think I'll pick up a few more. I've been waiting for months for these to come on sale again, it seems like they have them about twice a year.
