AeroShell Oil 15W-50

Description

You’re preflighting your Cessna 182 on a cool morning, and you know that getting the right oil viscosity matters—especially if you’re operating across variable temperatures or altitudes. AeroShell Oil 15W-50 is a multigrade aviation oil formulated to flow smoothly at cold start while maintaining proper film strength during cruise and climb. This oil suits engines operating in temperate to warm climates and is widely used in Lycoming and Continental engines where the 15W-50 weight is approved and recommended.

Before you add any oil, verify your engine’s Approved Flight Manual or Type Certificate Data Sheet to confirm 15W-50 compatibility; some engines specify different weights depending on season or ambient conditions. The 15W designation ensures adequate flow during start-up, while the 50-weight component protects bearing surfaces under load. Check your engine’s total capacity and top-off accordingly, keeping detailed maintenance logs of consumption and oil condition for your records and resale value.
