    The oil, If used oil simply clogged the filters up.
    Sometimes the saving on mixed fuel does not equel to a set of new filters.

    I tried to mix unused multiweight oil into the diesel fuel with the same results that the OP posted about, same results as his. After running it for 50 miles in the 35-40mph range (anything above 40, made it start missing again) , I stopped for fuel & put in 15 gallons of fresh diesel fuel. This new fuel thinned out the mix & the truck ran great for the next 50 miles home. I never mix UNUSED motor oil into the fuel tank again & the truck runs great now. Fuel filters are changed every few years & they are nowhere near as clogged looking as the ones the truck came with. Used motor oil, goes to the recycle facility only; never into the fuel tank. Injection pumps & fuel injectors are @ risk if you use it for fuel.

    When we mixed in engine oil to the fuel back when I was in the Marines, we mixed it with gasoline not diesel. That way you had a mixture more like diesel in the end.

    Ive got new, usgi secondary filters for $5 each plus shipping. They come with all the correct gaskets.
    Don't worry about the size difference
