Can the motorcraft FL500S filter, which crosses to an AcDelcoPF63, be safely used on a GM 4.3 DI engine? I'm just concerned due to different bypass specs. When you look up the Wix cross for a 500S, it gives a Wix 57502 with aa 22 psi bypass versus the PF63 cross which is a Wix 57045, and has a 12-15 psi bypass. However Baldwin filters crosses to a B7449 for both an FL500S and PF63. So in other words is it safe to use a motorcraft filter in place of the AcDelco and vice versa? Truck in question is a 2015 Chevy 1500 with the 4.3
Secondly, my buddy has a 2013 Impala 3.6 DI with 145k miles. As I've mentioned before he goes till the OLM hits 0% with the cheapest Dexos oil and filters, no problems yet. We will be removing the manifold soon to change the spark plugs soon so I'll get a good look at the buildup on the valves. He found a local parts store where he can get Pronto filters (Chinese made) for around $2.49 each. So with Supertech 5W30, he can do an oil change for around $25. Should the Supertech with the Pronto filter be fine for an oil change down to 0%? Doing this the OLM usually hits 0 around 5000-5500 miles each time.
