I have been developing a preluber/oil change system for the big diesels and showed it at an equipment show in RI. It looks promising. I had to make a new one for the Ft Laud. boat show. Sofar people like it. Picture below. The base is 7.5X10.5"
and has a gear pump 3 gal. min 12V. Has a limit pressure valve set to 30psi. after that goes in to a loop.
It pressurizes the oil system before start
You can evacuate the oil pan
and pump back fresh oil with the same unit
Keep your fingers crossed

Sounds great Bulent for aircraft engines too. A lot of aircraft engines sit
around for months too. Just like pleasure boats. What does it weigh?

I didn't think to check the weight. For aircraft use, if it is not used as a permanent mount, I guess weight does not matter. If it's mounted permanently, there is a room for slimming the weight.: like aluminum AN fittings, no need for oil drain valve and some reduction of the base. I will weigh it as is in the morning and let you know.
Also after the show I will make up a light weight version and send you one to evaluate Paul.
BTW during testing I was surprised how much flow this fist size pump is putting out.

I need something like that as I am getting ready to start the O-470 for the first time in
a year.

A possible scenario for aircraft use is having dry break quick disconnect couplings 
so only when the engine has been sitting around for weeks need it be used.
