Don't happen to know who makes the OE filters do ya Frank?
The closest Mitsu dealer closed down here last year, the next closest I know of is is multi dealer (BMW, Nissan, Subaru, Mitsu) and they are a PITA to deal with. I'm 99% sure the Dodge dealers would hand me a MoPar or a Fram, neither one seems to be a full-on company shop. I'll try the interweb. I really dislike the parts stores around here, NAPA has always been good to me, finding parts for everything from my Isuzu to my Yanmar, but Kragen only caries major brands and wal-mart is what it is.
What is the OE spec for oil? is it 5-30?
