1. I believe the oil filters may interchange. Look at the mounting base on your truck. One of the trucks I had had a wide gasket mounting surface that would let it take both filters, the fat one and the slender one.
2. Before you knock the lesser priced filters, just a thought. I had an 83 Pup I bought in 88. I used all brands of filters. I started off with WIX because that was all I could find, but they were almost $10 dollars 18 years ago. Then I just started using the ones from Autozone, the Deutch filters. (I am thinking they were the D434?) I believe these have been replaced by STP, but AZ no longer carries the oil filters. I think Pep Boys does, however. I also used the Fram and Duetch air filters, I believe the A326. I did change the oil somewhat regularly, most of the time using the cheapest 15W-40 oil I could find. I believe most of the time this was the WalMart brand, or the Coastal brand from AZ. Much to my shame, I don't think I changed the fuel filter more than 4 or five times in all the years I owned that truck. The result of using cheap filters and oil? The guy we sold this truck to is still running it around the area here. I have seen it in the last month or so. (It is so ugly now even I wouldn't drive it). The odometer stopped working at 185,000 in about 1992. It had 62,0000 miles when I bought it. We estimate it to now have around 380,000 to 400,000 miles on it. The engine never gave me any trouble, other that changing glow plugs. Maybe cheap filters and oil aren't that bad.
P.S. It has never had the timing belt changed either, unless it was done before I got it.
