I agree with some of the others, the oil that's put there should stay there until displaced by something or burned (just like a sealed bearing). If you use a heat activated co-polymer the oil will resist squeeze-out at higher temperatures. The hotter it gets the tighter in stays on the bearing surface. As long as the engine is cooled beyond the ignition point of the oil it should last indefinitely. Why don't all engines use this? Oil performs many functions including removal of dirt and contaminants. The slower the oil evacuates the bearings the more damage is done by the trapped particles. Also (if using a heat activate polymer) as the oil expands it will impregnate the dirt onto the bering surfaces resulting in scoring. Bottem line, the engine may run fine "dry" but it's still toast at the end of the day. Seen the same thing in "extended drain" sythetics when people use them off road. They may be rated for a 100,000 miles without a change in highway engines but wate the bottem half of an engine in off road applications.
