What is AeroShell W80, W100?
Both AeroShell l W80 and W100 are aviation piston engine lubricants formulated specially with ashless dispersant additives. This means that the W80 and W100 lubricants will provide your aircraft engine with exceptional lubricating performance while helping to avoid the build-up of metallic ash residues on critical engine components.
How is W100 different from W100 Plus? AeroShell Oil W100 Plus and W 80 Plus are single grade oils that combine proven AeroShell ashless dispersant technology with advanced anti-wear, anti-corrosion and metal passivator additives. With these three additives, your engine would receive extra protection against wear, corrosion, and rust. The metal passivator ability would also protect the oil from being degraded quickly by the copper present in the oil.
Which AeroShell lubricants contain Lycoming LW16702 additives?
As a rule of thumb, the lubricants in the plus series all contain lycoming LW16702 additive in the correct proportion and meets Lycoming requirements as well as the US Federal Aviation Authority Airworthiness directive 80-04-03. Aeroshell W 15W-50 also contains lycoming LW16702 additive despite it having a different product name. On top of the W80 plus and W100 plus series, W 15W-50 is the only semi-synthetic lubricant which contains advanced additives for superior performance in extreme weather conditions.  What this means for owners of lycoming engines is that you would not need to add additional LW16702 additives when you use the W80+ and W100+ oils.
What difference would the ‘plus’ make?
There is the perception that licensed lubricants provide adequate engine protection as all licensed lubricants meet the same product regulations, and thus choose products based on price. However, the magnitude of aircraft engines as well as infrequent flying patterns of some aircrafts means that dormant engines are exposed to more corrosion issues than expected. Thus, a lubricant which provides extra protection would be crucial to maintaining top performance of your aircraft engine.
