Your right blykins was trying to make a point.Think then about compression ignition diesel engines that are started every day like their counterpart gas engines and how long these motors last.
One example Amsoil advertizes is a trucker with bypass filtering went 409,000 miles on one oil change,course he had his oil analyzed periodically.
I do believe in the Accusump or something similiar for racing and for those that feel the need on their pride and joys.
As many engines as I have built or rebuilt and seen the condition some of them were in while tearing them down know for a fact what works and what is overkill especially on the street.Race motors presents another whole ball of wax.

I would imagine that a big diesel engine spends 90% of its time running anyway, so start-up wear is greatly decreased. These guys will put 400k miles on an engine in a couple of years, so it's a totally different application.

Regardless, if I were to spend that much money on a car, and that much money on an engine, the $400 bucks or so to eliminate any chance of wear just seems beneficial to me.

I see the resounding theme of that oil pressure builds up in a few seconds or so, but what happens in that few seconds before the oil gets there? Kinda hard to say and I'm sure it varies from engine to engine.

Cheap insurance.

I really don't know what would be the "negative" of buying a pre-oiler....cost? Fitment? The aggravation of activating it before you fire the motor? If it were offered for free, would you all still pass on it? Or would you say, "Yeah, give it to me."

From time to time I find myself in discussions on various forums about engine building practices. I have expressed concern on different times about using Plastigage to build an engine, only to find myself in a heated argument about criticizing others' engine building practices. Even got myself kicked off of another forum for sticking to my opinion....hahaha

Regardless, the words I kept hearing were: "If I were to buy an engine from you Brent, I would expect you to check the clearances with a mic and bore mic and map them out. However, I can't afford to buy a mic, so I use Plastigage."

It's the same thing here....I'm offering my opinion, but if you guys were to buy an assembled car/engine package from me (if I did that sort of thing), there would not be much said about it if I stuck an Accusump in there. So where is the line drawn?
