can't hardly buy a jug of synthetic blend and a decent filter for less than 25-30 bucks anymore. i would say this is pretty hot.
autozone usually has good deals with castrol or other name brand oil, but it always includes a garbage filter.
Prices here are $25.xx for 5 quarts of Mobil1 at Wal-Mart ($20ish for 4 quarts of Shell Rotella T6 5w40). I use OEM filters at ~$5/ea (I stock up when I order parts online).
Yeah, I get 5w30 synthetic for about 25.xx for the 5 qt jug too around here. Sometimes lower like 22.xx
w/o filter, so OPs deal still a decent deal
