AeroShell Aircraft Engine Oil for Summer Flying

Summer flying can increase the importance of oil selection because aircraft engines may see more frequent use, warmer conditions, and longer periods exposed to humidity between flights. The single grade heritage of AeroShell W100 Plus means outstanding protection especially in the humid summer months, which exposes your engine to higher risk of rust formation. The added anti-corrosion additive provides enhanced protection to your engine to prevent rust.

AeroShell W100 Plus contains enhanced anti-wear additives to protect your engine especially when your aircraft is clocking more miles during flying season.

The ashless dispersant additives in AeroShell Oil W100 Plus are designed to stop dirt particles from joining to form harmful sludge deposits. These combined with extra anti-corrosion and anti-wear additives offer better protection and therefore prolong the life of your engine.

Additional Maintenance Tip: For optimal performance, it’s recommended to change your AeroShell aircraft engine oil every 25–50 flight hours, depending on usage conditions and engine type. If switching between oil grades (e.g., from W100 to W15W50), check manufacturer guidance to ensure compatibility. Regular oil analysis and filter inspections also help detect early signs of wear. Before busier summer flying periods, confirm the selected AeroShell oil grade against the aircraft maintenance manual and review oil condition, filters, and recent usage patterns as part of routine preparation.

AeroShell’s trusted portfolio of piston engine oils offers peace of mind to aircraft owners, flight schools, and pilots through the summer months. This includes AeroShell aircraft engine oil, designed to perform in all flying conditions.

As the covers come off, it is important to ensure all aspects of your aircraft are in perfect condition before your first flight. These simple tips may help in ensuring your first flight is a safe one.

• Ensure the battery is in good condition and fully charged, ideally using a slow “trickle” charger.
• Check the fuel for water. The best time to do this is first thing in the morning before the aircraft is moved.
• Conduct a full walk around of the aircraft, checking the brakes as well as exhausts and inlets for signs of obstruction.
• Check the engine, turning it over on the starter motor with the fuel, magnetos and mixture lever turned off. This will allow oil around the engine ahead of a brief ground run.
• Drain the preservative oil and change the filters, before refilling with the operating oil of choice.
• Check lubrication points across the airframe, including joints and linkages and replace with new grease where necessary.
  
• Check the Perspex of the cockpit canopy for scratches or other marks that should then be removed with specialist polishing kits.
• Ensure full and thorough pre-flight checks are completed. Returning an aircraft to an operational state should always be carried out by trained operatives in conjunction with the aircraft maintenance manual and any other important documentation.
