Bought a toyota oil filter other day from dealer. Forget who makes it, but said maid in tiawan. Its a black filter, for $6.79. i have done research here and forums, like on mobil oil filters, fram extend guards, napas ect..i do my own changes every 3 months(LOTS of stop n go traffic, oil is always thick black, and 1,000 miles only). Right now i have a fram extend guard, and like it alot. seems to be very good at oil flow, and filtration. the napa white ones are also rated exxcellent, for a fraction of the cost, also at oil flow and filtration. but for the toyota one..how does it compare too those?
