NO... I'm not suggesting that at all. In fact the opposite. It takes about 10-20 sec. minimum (temp dependent, etc.) of running to fully charge the oil galleries, pressurize the system and float the moving parts.
What I am saying is that eliminating engine wear on startup is a fallacy, marketing hype by using one oil over another. The only way to significantly reduce startup wear is through a pre-luber.
Sure, the better an oil clings to metal parts while not running, the less friction it'll experience on startup, but it will not be eliminated and over the life of the engine, you'll still see 80+% of the wear accumulate from startups.
That's one of the reasons why cars with 'Highway' miles are so desireable. They experience many more miles between starts and over the life of the car can literally have thousands of fewer startups than the little old lady driving 3 mi. once a week to church and back.
