9/1/2023 0 Comments Aviation mineral oil viscosity![]() The ashless dispersant formulation helps minimize the formation of engine sludge, varnish, piston deposits and combustion chamber deposits, resulting in a much cleaner engine compared with the use of straight (non-dispersant) mineral oils. These oils do 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. It maintains its film strength under high loads and at high temperatures to protect against wear and piston scuffing. AeroShell Oil 80 straight mineral oils blended from selected high viscosity index base oils. It provides distinct performance benefits compared with single-grade engine oils, including easier starting and faster oil circulation at low temperatures, reduced warm-up time, and reduced oil consumption in most engines. According to Visser, temporary shear loss in a 50-weight mineral oil can reduce its effective viscosity to that of a 5-weight. They combine non-metallic additives with selected high viscosity index base stocks to give exceptional stability, dispersancy and anti-foaming performance. It is a transparent, colorless oil composed mainly of alkanes (typically 15 to 40 carbons) 1 and cyclic paraffins, related to white petrolatum. AeroShell Oil W100 Mineral ashless dispersant oil for aircraft piston engines AeroShell W Oils were the first non-ash dispersant oils to be used in aircraft piston engines. When operating in colder environments Aeroshell W80 or W80 Plus Anti-wear (SAE 40 wt.) and, of course preheating is recommended. ![]() These oils do not contain any additives except for very small. Description Product SDS Sheet Mineral Oil Light Viscosity From Wikipedia, the free encyclopedia Mineral oil or liquid petrolatum is a by-product in the distillation of petroleum to produce gasoline. RAM recommends Single Viscosity Mineral Based (AD) Oils such as: Aeroshell W100 and W100 Plus Anti-wear (SAE 50 wt.) when typical ground level engine starting temperatures are not less than 40° F. Phillips 66® X/C Aviation Oil is an ashless dispersant, multi-grade engine oil specially formulated for year-round use in aircraft piston engines. AeroShell Oil 80 straight mineral oils blended from selected high viscosity index base oils.
