Lubricating oil W100 Plus

piston engine

Product overview
AeroShell Oil W100 Plus is a single-grade aviation piston engine oil that combines ashless dispersant technology with anti-wear and anti-corrosion additives. It is formulated to provide enhanced protection for piston engines, particularly in applications where a single-grade lubricant is preferred and ambient temperatures are moderate.

Features and benefits

• High-performance additive system: Protects against rust, corrosion and wear to support component longevity.
• Enhanced wear protection: Contains the Lycoming LW 16702 anti-wear additive to protect camshafts and lifters.
• Ashless dispersant technology: Minimises deposit formation for cleaner combustion and sustained engine performance.
• Improved load-carrying capacity: Reduces metal-to-metal contact under load, helping to extend service intervals.
• Recommended ambient range: Optimised for operations approximately between 16°C and 32°C (60.8°F–89.6°F).

Specifications & approvals

• SAE — J1899 Grade 50
• FAA — AMOC to Airworthiness Directive 80-04-03 R2 p.1b
• Lycoming Engines — Service Bulletin 446E and 471B; Service Instruction 1409C
• Continental Aerospace Technologies — MHS-24; SIL 99-2

Applications
The formulation provides improved rust and wear protection compared with conventional single grades. Additives form a protective barrier on critical parts while the aircraft is idle, helping to maintain camshaft and lifter film and reduce the risk of premature damage. Suitable for piston-engine aircraft operating within the recommended ambient range.

Health, Safety and Environment

• Consult the Safety Data Sheet (SDS) for handling and exposure guidance.
• Dispose of used lubricant at authorised collection points; do not discharge to drains, soil or water.
