Lubricating oil W100

piston engine

Product overview
Designed for moderate climates, AeroShell Oil W100 is a single-grade, ashless dispersant oil formulated for certified four-stroke reciprocating piston engines. It provides consistent lubrication and protection across a moderate ambient temperature range. SAE J1899 Grade 50.

Features and benefits

• Suitable for moderate temperature range: Performs best between 16°C and 32°C (60.8°F to 89.6°F ambient air temperature).
• Designed to keep particles separated: Uses ashless dispersant additive technology to minimise deposit build-up and support cleaner combustion and efficient engine operation.

Applications
AeroShell W Oils are available in three viscosity grades: AeroShell Oil W80, AeroShell Oil W100 and AeroShell Oil W120. The suffix for each grade corresponds to the viscosity of the oil at 210°F measured in Saybolt Universal Seconds. AeroShell W Oils are intended for use in certified four-stroke (four-cycle) reciprocating piston engines, including fuel-injected and turbocharged engines. They are not recommended for use in automotive engines. Many radial-engine operators select AeroShell Oil W120 for warm-weather operations; AeroShell Oil W100 or AeroShell Oil W 15W-50 are common for cooler ambient temperatures. For many Lycoming and Continental flat engines, AeroShell Oil W100 or AeroShell Oil W 15W-50 are frequently chosen; in colder conditions AeroShell Oil W80 may be used instead of W100 to improve cold-start performance.
