I always worry when I read about a long idle engine being prepared for new use.
Once the three necessary components (spark, compression and fuel) are ready, I would like to have the oil system briefly under pressure before starting the engine.
A small hand or electric pump could be used to bring the oil up to capacity by injecting it through any access point directly from one or more of the oil bottles you were just going to dump down the filler hole.
Wouldn't you feel better to know that all the crank and cam (and other) bearings have nice clean oil already in place?
There used to be a similar device available through the old MG Mitten store. Old Ford tractors can also be oil primed.
