Multi-Grade, Normal Operation Ashless

Multi-Grade 15w-50 & 20w-50 Aviation Oils for Normal operation are crafted from the finest synthetic and petroleum base stocks and infused with select additive systems to provide High Viscosity Indices (HVIs) are formulated to work with several aviation engine types.

These oils are classified under SAE 50 oils due to their ability to change viscosities – at operating temperature, both 15w-50 and 20w-50 have the same viscosity, hence the number “50.” These aircraft engine lubricants are intended for year-round usage and are some of the most popular aviation oil weights available.

20w-50 Oils have a slightly higher viscosity and engine startup when compared to 15w-50 oils; once in operation, though, these oils may have very similar performance characteristics. Refer to OEM specifications and product data sheets to determine which variety may be more suited to your aircraft and your climate.
