hi sages - know this general subject has been discussed before and the consensus seems to be- use mann. just changed oil in the 92 224k miles . runs fine. used 10/30 and a mann filter. these filters are a little hard to find and cost $6 or more each. my question is this- in most of my cars since 65, dodges and plymouth slant sixes, ive used standard purolator filters with no problem. they are an old american brand made here and are about half the price of manns. the classic model filter claims a 97.5% efficiency rating and various features that include an anti drain back valve. does anybody have an opinion of these filters on volvo 240s. the number called for volvos is L14670 and looks exactly like the mann. never heard any criticism of purolators but have on fram , wix and off brands. as always i appreciate the sagery in the replies. thanks tons . oldduke
