Just a crazy old Structural that likes to break things - and fix them.

If we believe all the oil advertising and engine mfgs, they say the worst engine wear happens during the first few seconds of startup due to lack of oil pressure.

Why not install an auxiliary electric oil pump that cycles for a few seconds before ignition and then shuts off once started.  Seems simple and couldn't cost too much.  Or am I just missing something here?? Lots of race cars do this. Here's a solution that doesn't used an electric pump, but a precharged accumulator. Captures oil at pressure at shut down, and releases it back into the oil gallery at start. (or when you have a transiet drop in oil pressure)

and the reason it isn't fitted to passenger cars is that /you/ don't want to pay for it, both in variable or fixed costs. It might extend the engine life from 200000 miles to 400000 miles. Nobody of any financial significance is interested in that. Cars are sold to the first buyer, so long as they make it to 100000 miles that is all that matters. Sorry about that.
