If I lived in Minnesota or Arizona I would use the same thing. I change the filter every time I change oil â once every twelve months or 6,000 miles. Harold McElraft - 3354 <<<<<< Harold, you are right on about everything that has to do with oil and reading the weight lingo and such, but i think most owners are convinced that the purflux filter is a better match to the engine than either Hastings or NAPA Gold. Do the ones you use have an anti-drain back valve? if not, you could be wearing your engine down every time you start it for just a few cents savings!! i have never tried either of those two.
