Heres a potentially crazy idea. Has anyone used a transfer pump and high grade 0.5 - 1um filter to periodically (say every 100 miles) remove particulates from engine oil. I have a high pressure pump and some Balston filters that I was considering trying. My plan is to filter (a slow process) into a clean polyethylene carboy and then transfer back into the engine. This would be an alternative to a bypass filtration set-up.
