Don't know about the thicker oils, but an aviation enthuisiast friend showed my an article comparing dino and synthetic oil for use in reciprocating aircraft engines. The Mobil 1 Aviation oil was touted as sticking to metal parts _much_ longer than the dino oil. Mobil's tests was to dip pieces of steel in dino and mobil 1, then subject them to hot, humid, salty air. The dino oil piece showed its first rust within hours, the mobil piece lasted for a couple days before they stopped the test. I'm not particularly worried about rust inside my engine, but it is nice to have a thin film of oil on all the bearings at start up! Mobil says that mobil 1 sticks better because it is more "polar." I guess that means that it only sticks well to ferrous metals, and not aluminum. Interesting, no? ------------------------------------------------------ Jason Douglas MTS Dept G057 MITRE Corporation
