I remember reading an article by Smokey Yunick back in the 1970's describing a similar process, except he used kerosene and ran the engine for 30 seconds (!). I'd be afraid to ever try this myself.

The closest I've gotten is using 10W30 Agway Super Diesel oil this winter. I figure that this oil is rated for properly lubricating a diesel engine up to 50 deg F, and the thinner viscosity should help remove a bit more sludge than my usual 15W40. I do notice a faster warmup to normal power levels.
