The reason I suspect it could be a problem is the very same reason that you have to pre-fill a top up exchanger at install. Air in the oil cooler system has to pass through the engine before the engine sees lubrication at startup. If you were to not fill the heat exchanger at install, an entire liter-sized bubble would pass through your engine--which is why Z1 states that you HAVE to fill the core with oil at install.

If the hose is drained of oil, that 'bubble' (which is really the volume of the entire hose) would have to pass through the engine lubrication system before the engine (cams or crank) would see oil. This would just be a second or two, but I would think that it could create wear.

Anyway. Like I said, it could be paranoia... but I would love to see results of an oil analysis... especially if someone has already done one.

... Brother... You don't know why they say to do it then... And this is going to seem prickish, but I don't think you know how the system works either.

The engine has air in it. More air than oil.

You have to prefill the cooler because if you start it without filling it, you will effectively drain out 1+ quarts of oil out of your engine into the cooler, and you may cause the engine to STARVE itself. Not because of a bubble.

And it takes longer to warm up for 2 reasons:
1) The thermostatic plate is never closed, at "closed" or cold, it's circulating something like 20% of it's flow capability. Then it opens to 100% at 180 degrees
2) There is somewhere on the forum that says that the temperature gauge will read about 20 degrees cooler than it really is because the placement of the thermometer; it is right by the inlet (right out of your cooler)
