Maybe off-topic, but I'm a bit confused about this 'sludging' thing. It's supposed to be from the engine running at high temperatures, no? But a water-cooled engine can't get much above boiling (unless maybe some of the oil is going through a turbo?), while air-cooled engines used in airplanes car run oil temps at 245 F (Lycoming's recommendation for continuous use) or higher.
