Great work Dan.
When I see a cold start, short run engine last 500,000 miles like a warm long distance engine will often run - I'll accept that pre-lube has no anti-wear benefits - but I've never known a short distance engine (that seldom gets a chance to get hot) do those miles - they always wear out.
Everyone knows that a car that gets long runs will last a LOT longer than a car that only gets short runs - and although other factors come into it - wear is one. The oils do leave a film but it does not reduce cold wear to ZERO as implied by Tom. There is wear - it is just small but accumulates over time.
Is the anti-wear on start up enough to justify the expense of an accumulator? MAybe not - but it is A FREE side benefit of having one that was bought mainly to protect the engine under those big long sweepers - which IS WORTH the cost for those that have run bearings without one.
