I was in Advanced Auto Parts today and was surprised how expensive all the major brands were. I know prices have gone up dramatically over the last 2 years. PP - $5.38 M1 - $5.68 M1 EP - $6.68 QS - $5.49 MC - $2.68 Havonline - $1.98 Syntec - $5.90 I could be off by a few cents bc I could not remember all the exact prices but they were in this range, +/- .15. IMO, the Havoline/MC were the two best bargains among all of them. I thought PP was cheaper? Maybe at Walmert in the 5 gallon jug?
