Spinner II model 25 is a heavy-duty oil cleaner for all diesel pickup trucks. Protect your engine against premature wear. Spinner II systems remove contaminants of all sizes - including soot and other solids as small as one-tenth of a micron! Provides bypass filtration, diverting a small side stream of oil (approximately 0.8 gpm or 3 lpm by volume), cleaning it thoroughly and returning it to the crankcase. The key is a powerful, high-efficiency oil cleaning centrifuge. It generates centrifugal force 2,000 times greater than gravity - literally slinging solid contaminates from the oil and depositing them in a cleanable, reusable bowl. Holds up to 250 cc of contaminants.
