Superior rust and corrosion protection giving that extra protection to engine parts that may be susceptible to extreme rusting when an aircraft is not in use.

AeroShell Oil W100 Plus and W 80 Plus - The Premium Single Grade Aviation Oils. .Single Grade Ashless Dispersant Engine Oils: AeroShell Oil W100 Plus and W 80 Plus are new single grade oils that combine proven AeroShell ashless dispersant technology with advanced antiwear additives. They are the oils for pilots who want a single grade that delivers extra protection and performance. AeroShell Oil W 100 Plus and W 80 Plus brings together the best qualities of two of the world's best-selling four cycle aviation oils.

They have the single grade, ashless dispersant performance found in AeroShell W 100 and W 80 and the anti-wear/anti-corrosion additives of AeroShell Oil W 15W 50 Multigrade. Their single grade heritage means outstanding resistance to heat, especially in the summer months. Their ashless dispersant formulation helps reduce deposits of harmful metallic ash in combustion chambers. And their advanced additives work against rust, corrosion and wear in a way no other single grade does. There are simply no better single grade aviation oils


  • Lycoming Service Bulletin 446C and 471, plus Service Instruction 1409A
  • MIL-L-22851(obsolete)
  • SAE J 1899
  • Continental recommended
  • FAA Airworthiness Directive 80-04-03
  • AeroShell Oil W100 Plus and W80 Plus are the only single grade oils blended with this antiwear additive technology. That means that owners of Lycoming model engines, specified in the applicable service bulletin, don't have to add any supplemental additives to the oil.
  • AeroShell Oil W100 Plus and W80 Plus can be used in any certified engine, this includes: Lycoming; Continental; Pratt & Whitney radial and most radical, opposed or in-line engines.
  • AeroShell Oill W100 Plus and W80 Plus are not recommended for use in helicopter with a common sump for the engine and transmission. The anti-wear additives makes the oil more slippery than regular single grades. This can cause the transmission to slip. The product is not recommended for the breaking in of a new engine for the same reason.


  • Superior rust and corrosion protection giving that extra protection to engine parts that may be susceptible to extreme rusting when an aircraft is not in use (for prolonged periods of non-use please use AeroShell Fluid 2F).
  • Improved anti-wear characteristics particularly at engine start-up and eliminates the need for supplemental additives required by certain Lycoming engines. AeroShell Oil W100 Plus and W80 Plus already contain the Lycoming additive LW 16702 in the correct proportions and meets Lycoming requirements as well as the US Federal Aviation Authority Airworthiness directive 80-04-03.
  • Promotes Engine Cleanness. The non-ash forming, polymeric additive was developed to help eliminate the harmful combustion chamber and spark plug deposits that form during normal operation.
  • High Viscosity Index Base Oils used in AeroShell W oils maintain their viscosity and help protect engine components more effectively under the high shear stresses that an engine places on lubricants.
  • Provides Compatibility with other approved aircraft piston engine oils. Mixing with other products, however will result in some loss of the superior performance features of AeroShell Oil W100 Plus and W80 Plus.

The oil was great, and the price was good. We flew into KAJO and called to have it brought to the airport. I have flown in before with a friend who orders parts from you all the time. Delivery was always prompt. This was my first order with you. We waited over half an hour and nobody showed up. It took 2 calls and 45 minutes but it finally arrived. Im sure it was just an oversight on my order. No problem.

Time & use will tell, of course, but Aeroshell seems to have taken state of the art to a slightly(?) new level with their special anti-wear additive in this Plus oil. Priced at a new level, too, its almost as expensive as a major repair for a mere change of oil. ...hopefully worth it.

Q: I operate a Lycoming O-360 in tropical climat. Temperatur up to 100F. Humidity exeeding 90%. Is Aeroshell W100 SAE50 PLUS the right oil? Should I add Camguard Additive?

Yes, this oil will be fine in that environment and it is recommended that you add CamGuard.

Q: Is Aeroshell Aviation Oil W100 Plus a synthetic oil?

No, it is not a synthetic oil.

Q: The last case of Aeroshell W100 plus came in black plastic bottles. The new case i just bought has red containers. It also says it is a mineral Ash dispersant oil. It never used to say mineral before. Is this the same oil, or is it an engine break in oil?

It is the same oil as before. The only thing that changes is the packaging. All AeroShell oils will be switching to the new, red packaging.

Q: Will using CamGuard degrade the Aeroshell plus oil? Will CamGuard add extra protection for Aeroshell 100 plus?

Per Vendor: CamGaurd will enhance any oil that you put it in. There are very few additives actually in 100+ oil. CamGaurd has 11 different components.

Q: I am looking for Aeroshell fluid 2F. Do you sell this product?

Aeroshell 2F fluid has been superceded to the new 2XN fluid. The 2XN can be found under our part # 08-14701.

Q: The specification of the Aeroshell W100 Plus says Lycoming owners do not need to use additives with this oil. Does that mean I do not need to add the Lycoming LW-16702?

No, it will not need the Lycoming LW-16702 added as it already has a cleaning additive in the oil. That is the benefit between the W100 Plus and the W100 regular.

Q: what is the difference 100W and 100w plus?

100W Plus will have an additive in it to prevent rust and corrosion while the 100W does not have this additive.

Q: Is the shipping on cases of oil free if the entire order is over free shipping minimum?

Yes, as long as it is shipping in the USA (excluding Hawaii) it can ship with the free freight promotion.

Q: Can you mix this Aeroshell W100 Plus oil with regular W100?

Yes, this is the same oil but the Plus has an additional additive.

Q: How many pots does the box bring?

Part# 08-05486-6 is a case of 6 quarts.
