If you were driving the truck every day, having an oil filter might make some sense. But these days with the trucks being used for only occasional driving, and easy non work related driving to boot, a filter may not be a necessity. Change the oil every 1500 -2000 miles, or at least once a year depending on what comes first and you will be perfectly fine.

One other benefit, because these filters are bypass filters, that is they bleed a little oil and pressure from the main galley, filter it and then dump it back into the pan, not back into the main galley, you will likely see better oil pressure if you remove the filter.

If you are really set on a filter, go to a remote spin on, one of the aftermarket versions, they generally use like a Fram PH8, and mount it on the inner fender somewhere (so it’s easy to change). But you have to either use lines with the same ID as stock, or you have to use reducer fittings at the filter housing that get you to the ID of the stock hoses. Otherwise you will in fact pull too much pressure from the main galley and then you will run the risk of hurting the motor.

One of my motors, a heavily modified 261 that I run pretty hard, does not run a filter. I change the oil every thousand to fifteen hundred miles, or once a year.
