Multigrade Aviation Chemicals AeroShell Oil W15W50 SAE J-1899 Grade

AeroShell Oil W15W-50, Standard Number: SAE J-1899 Grade Multigrade

Overview

Specifications

• Avco Lycoming 301F (Service Bulletin 1014J and revisions, 446C & 471)
• Teledyne Continental MHS-24B (Service Bulletin M81-11 and revisions)
• Pratt & Whitney All radial engines (Service Bulletin 1183 revision R)
• FAA Airworthiness Directive 80-04-03

Benefits

• Promotes Engine Cleanness. The non-ash forming, polymeric additive was developed to help eliminate the harmful combustion chamber deposits that occur during normal operation.
• Multigrade Performance allows for improved engine operation in temperature extremes.
• Excellent Low Temperature characteristics provide easier cold weather starting and rapid lubrication of engine parts.
• Reduces Oil Consumption in some cases by up to 50% and resists thickening at low temperatures.
• Protects against oil cooler plugging.
• All Season oil function since there is no need to change from a winter / summer grade depending on the ambient temperatures.
• High Viscosity Index Semi-Synthetic Base Oils used, 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. Since AeroShell Oil W 15W-50 is fully approved to SAE J-1899 and is listed on the relevant Qualified Products List (QPL), elaborate precautions are not needed when changing from similarly approved aircraft engine oils, as long as these oils are qualified products.
• Reduces Fuel Consumption by up to 5% over straight grade engine oils.

FAQ

Q:What is the anti-corosion additive in the 15W-50 ?

A:The anti-corosion additive system is designed to prevent rust or corrosion in all types of aircraft piston engines. In comparative testing of camshaft rusting under high humidity conditions, AeroShell Oil w 15W-50 was almost entirely rust free while other camshafts conditioned on other oils showed sometimes heavy rusting on cam lobes and bearing surfaces.

Q:What is the main applications of the 15W-50?

A:AeroShell Oil W 15W-50 is intended for use in certified four-stroke cycle aircraft piston engines. AeroShell Oil W 15W-50is superior to single grade oils in almost every application.It offers easier starting, better lubrication after start-up,reduced wear, reduced corrosion and rusting, and improved cleanliness with oil pressures and temperatures equal to that of single grade SAE 50 oils at fully warmed up conditions.
