If you like to extend change intervals, a larger filter might help. Just make sure the filtration level and bypass pressure are the same. And you may need to add a little extra oil to the crankcase. |
Finally, someone else with an engineering degree? Pressure is the answer. The lube system of your engine is designed to specific pressure drop values. A ton of engineering goes into the flow characteristics of the rifles, feed hole diameters, filter head, and filter. It's called fluid dynamics. Use the filter specified for good reason and stop guessing.
