The numbers do not always follow a sequence. In the case of turbine and piston engine oils the number relates to the oil viscosity; for...

In selecting an AeroShell Grade for a non-aviation application the properties of the grade must be examined. This will only give an approximate indication as to the expected performance in the specific application. However, such data must be regarded as guidance only. There is no laboratory test that can give a complete prediction of performance in the actual use, and the final stage in any decision must involve performance tests in either the actual equipment or in the laboratory/test house under conditions expected in service. Specifications The majority of AeroShell products are...

As an aid to users, details of French and Russian Specifications are included but specifications of other countries are not included. Over the years, changes were made to both U.S. and British Specifications. The U.S. authorities eliminated the older MIL specifications (e.g. H = hydraulic fluids; L = lubricating oils; G = greases) as they are currently known and replace them with performance specifications. These will be labelled MIL-PRF- followed by a number. Many MIL-PRF- specifications have now been issued and others will follow until all current MIL specifications have been converted....

On occasion, the specification on our AeroShell product labels may not always match that on the Certificate of Analysis (COA). In this instance we ask customers to please refer to the COA. AeroShell products are approved to the relevant Military, Civil or Original Equipment Manufacturer (OEM) Specifications. Whenever a revision is made to a specification, there is a change typically in the last alphabet to denote the latest revision. The COA changes are made earlier than the product label changes. This is because the labels are typically pre-printed on the packaging for supply chain and...
