various types of engines. The oil used in aircraft reciprocating engines has a relatively high viscosity required by: 1. Large engine operating clearances due to the relatively large size of the moving parts, the different materials used, and the different ... calibrated orifice is recorded as a measure of the oil’s viscosity. If actual Saybolt values were used to designate the viscosity of oil, there would probably be several hundred grades of oil…

engine, use only aviation grade straight mineral oil or ashless dispersant oil, as required, of the viscosity desired. If ashless dispersant oil is used in a new engine, or a newly overhauled engine, high oil consumption might possibly be experienced ... oils may retard the break in of the piston rings and cylinder walls. This condition can be avoided by the use of mineral oil until normal oil consumption is obtained, then change to the ashless dispersant oil. Mineral oil should…

compound that readily blends with engine oil when the mixture is heated to the proper temperature. The light mixture is available in three forms: MIL-C-6529C type I, type II, or type III. Type I is a concentrate ... grade 1100 oil to one part of concentrate. Type II is a ready-mixed material with MIL-L-22851 or grade 1100 oil and does not require dilution. Type III is a ready-mixed material with grade 1010 oil…
