Curt, some great info on the Amsoil site...thanks for sharing.
_______
AMSOIL Ea Bypass Oil Filters provide maximum filtration protection against wear and oil degradation. Working in conjunction with the engine's full-flow oil filter, AMSOIL Ea Bypass Filters operate by filtering oil on a "partial-flow" basis.
They draw approximately 10 percent of the oil sump's capacity at any one time and trap the extremely small, wear-causing contaminants that full-flow filters can’t remove. AMSOIL Ea Bypass Filters typically filter all of the oil in the system several times an hour, so the engine continuously receives analytically clean oil.
________
I think that we can conclude that all configurations...no filter, bypass or full flow... have all proven to be effective in these engines. Simply a matter of personal preference. I'll err toward more filtration, but that is a personal choice.
Fox, if you need a bypass canister for your installation because your full flow won't work, drop me a PM. I think I have an extra one or two laying around.
