Brief Description: Ordered Mineral Oil and Brake Fluid
I did a bit of research on what specific mineral oil and brake fluid is needed for the RV. Saw many posts and checked Aircraft Spruce. Looks like Aero Shell 100 SAE 50 Mineral Oil and ordered 7 quarts for the initial break in Period. Here is a brief description of the Aero Shell on the Spruce website:
“Aero Shell Oil 100 is a straight mineral oil blended from selected high viscosity index base oil. This oil does not contain any additives except for very small amounts of pour point depressant (which aids to improve fluidity at very low temperatures) and an anti-oxidant. Aero Shell Oil 100 is approved for all aviation piston engines of civil aircraft when the use of oil not containing a dispersant additive is required; however, it should also be used during the break-in of a new aviation piston engine or those recently overhauled.”
I also ordered a quart of Royco 782 Brake Fluid. It has a much improved flash point 445 degrees Fahrenheit under the new Mil spec 83232 vs. the older Mil spec 5606H.
“ROYCO 782 is a red - colored synthetic hydraulic fluid developed to meet the severe duty demands of today's military and industrial equipment. Modern additive technology is employed for oxidative stability, corrosion inhibition, and anti-wear protection. ROYCO 782 is compatible with petroleum based fluids and all components used in mineral oil type hydraulic systems. Mil-Spec: MIL-PRF-83282”
