pre-oiler for engine??
Was told that this device helps eliminate engine wear at startup. Dont really have any more info, but it sounds like a good idea. Turn the key and oil is pumped to cylinders right before engine cranks...

I just stuck a lot of cash into a new V-10 engine for our Excursion.
Race cars sometimes use pre-oilers because they typically immediately reach a high idle speed upon start-up, many run loose clearances to withstand abnormal heat and/or use high contraction forged pistons and their engines are pricy. Aircraft might benefit because they run at load (prop) immediately after start-up, and they are also pricy.
In spite of I having pointed out several possible scenarios, earlier, where a pre-oiler might be useful on our TV's, I am not going to install one on our new engine because I think that simple other factors, such as proper service intervals and quality lube materials, are good enough as others have stated.
If a pre-oiler/positive-oiler was truly valuable on consumer vehicles, I think it would be offered as a factory option. Not so in America, not even on high-G Corvettes. I wonder if it is even offered on Italian exotics?
Offhand, just as DirtyOil mentioned above, our locomotives had an electric post-oil system designed to oil-cool the stopped turbo upon shutdown. A sign noted not to open that particular breaker until it timed out, all to protect from coking the residual bearing oil on the hot turbo shaft.
