Preheat / Pre-Oiler

The faster a good oil film gets established on the cam, the less chance
there is of lifter damage. Anything under 60 degrees carries some risk.
We preheat below 40. A single cold start when it is really cold can
damage a lifter.

Which always leads me to this same question: Does anyone here have a
"pre-oiler" installed in their airplane?

It would seem so logical, yet I've never met anyone with one installed
(other than on big warbird engines...).

I have one on my Glasair Experimental. It is a Moroso (performance auto) unit.
It accomplishes 3 things. Pre-oil and pre-pressurize engine oil system 3 quart
capacity, Stabilized oil pressure (steady pressure), will maintain oil pressure
for the prop during aerobatics.
