Seem like pretty decent filters. Went to my R&S Strauss today as they have a 50% off Oil and Air filter sale going on. Bought my M1 filter for my oil change last week for 5 dollars. Figured I'd stock up on filters. Rather than waste 5 bucks on a mobil 1 filter(a great filter, but i have a 3.5Q Sump so my Xterra only gets 4.5/5k OCI's) its a waste really. Picked up 2 Purolator Classic's for roughly 5(little under). Might go back this weekend to the other location and buy two more(every other day and just stock up). its limit 2 per customer, but doubt they would remember me, and different shifts. So are these filters any good? I didn't feel like buying the PureOne version(the yellow turd) it looked the same just had the yellow gripage on it.
