My plan is to use 100% UMO with propane injection. The oil will be from a local lube shop, so mostly 10-30.
The motor will start on #2 until the coolant gets to 195. it will then preheat the UMO/RUG mixture thru a heat exchanger and pump it thru a 2 micron filter.
The propane will be controlled off a Hoof type governor operating an adjustable pressure regulator. I want to calibrate it where it is injecting 15% propane by volume. so i will burn 15 gallons of propane to 85 gallons of UMO.
