FWIW, when I worked in a buick dealership, we got a bulletin that if we had any customers that complained about a flickering OP light at idle on a 3.8, that we should change the OP sending units to a new part number that would come on at 2 P.S.I. The OEM switch came on at 5 P.S.I.

Obviously at idle the bearings require very little oil pressure to live a long life.

Also if you look at the older engines that relied on splash oiling, and had no oil pumps, they ran fine for quite awhile. Then there is the older Briggs and Stratton engines that ran on our lawnmowers, go karts, and mini bikes with just splash oiling, they lasted for decades, unless you did something really stupid.

30 seconds is nothing in the grand scheme of things, just like pre filling an oil filter when changing it, a complete waste of time. The engine is never going to know the difference whether the oil filter was pre filled, or the pump filled it, a non problem.
