Product Overview
AeroShell Oil W120 is formulated by Shell Aviation for piston aircraft engines that operate continuously in hot ambient environments or experience sustained high cylinder head temperatures.
With its very high viscosity (SAE 60), W120 maintains a strong lubricating film under extreme thermal stress, helping reduce metal-to-metal contact, oil thinning, and wear. It is commonly used in general aviation piston engines where straight mineral oils are specified and ashless dispersant oils are not required.
This oil is typically selected in regions with consistently high temperatures, where lower-viscosity grades may lose effectiveness.

Frequently Asked Questions (FAQ)
Q1. What is AeroShell Oil W120 mainly used for?
It is used in piston aircraft engines operating in hot climates or under sustained high-temperature conditions.
Q2. Can W120 be used in moderate or cold climates?
No. Due to its very high viscosity, it is not recommended for cooler environments or cold starts.
Q3. Does AeroShell W120 contain ashless dispersants?
No. It is a straight mineral oil without ashless dispersant additives.
Q4. Is W120 suitable for engine break-in?
Break-in procedures vary by engine. Lower-viscosity mineral oils are more commonly used unless otherwise specified by the OEM.
Q5. Can W120 be mixed with other piston engine oils?
Mixing with ashless dispersant or different viscosity oils is not recommended unless approved by the engine manufacturer.
