Engine pre run oil pump
helicopters use a pre oiler. Ever see them go through pre run procedures? One flick sends the oil pressure spiking then they turn on the turbine starters. Accusump or an oil accumulator can be made with an inverted pressure vessel plumbed into the remote feed line (easiest) and a 2 isolation valves. The system is charged when the car is running: Open the accumulator valve and let the running oil pressure fill the reservoir, then shut the valve. Now you got maybe 1/2 qt of oil under 50 psi of air pressure at the top of the vessel. When you want to start the vehicle after a month, close the feed valve behind the accumulator and open the accumulator valve, this will squirt the oil into the engine and register on the oil pressure guage for a few seconds. Open the supply valve, close the accumulator now you can start. Once the car is started, the accumulator can be filled back up with oil pressure whenever you open the accumulator valve to charge, then close that valve again. you could make the valves electric so this could be done in the car, or use a large check valve on the feed side. Whole system would be size of 2 valves and a 16oz water bottle and could mount opposite your rad puke tank for symmetry. Probably more for a monthly car. That accusump bottle is $324!!!
