Measurement of the Total Ash Content of Aviation Piston Engine Oils by a Calculation Method

E-38 Aviation Piston Engine Fuels and Lubricants
  • Ground Vehicle Standard
  • J1787_201108
  • Current
Published 2011-08-22 by SAE International in United States
This SAE Recommended Practice describes an empirical method for determining the theoretical ash content of aviation piston engine lubricating oils by calculating the equivalent weight of metallic oxides formed at 775 °C based on the metallic elemental concentration. The calculation method of ash determination may be used as an alternate to ASTM D 482 for application to the standards for aviation piston engine lubricating oils.

Lubricating Oils, Aircraft Piston Engine (Non-Dispersant Mineral Oil)

E-38 Aviation Piston Engine Fuels and Lubricants
  • Ground Vehicle Standard
  • J1966_201108
  • Current
Published 2011-08-22 by SAE International in United States
This SAE Standard establishes the requirements for nondispersant, mineral lubricating oils to be used in four-stroke cycle piston aircraft engines. This document covers the same lubricating oil requirements as the former military specification MIL-L-6082. Users should consult their airframe or engine manufacturers manuals for the latest listing of acceptable lubricants.

Lubricating Oil, Aircraft Piston Engine (Ashless Dispersant)

E-38 Aviation Piston Engine Fuels and Lubricants
  • Ground Vehicle Standard
  • J1899_201108
  • Current
Published 2011-08-22 by SAE International in United States
This SAE Standard establishes the requirements for lubricating oils containing ashless dispersant additives to be used in four-stroke cycle, reciprocating piston aircraft engines. This document covers the same lubricating oil requirements as the former military specification MIL-L-22851. Users should consult their airframe or engine manufacturers manuals for the latest listing of acceptable lubricants.

Measurement of the Total Ash Content of Aviation Piston Engine Oils by a Calculation Method

E-38 Aviation Piston Engine Fuels and Lubricants
  • Ground Vehicle Standard
  • J1787_200505
  • Historical
Published 2005-05-04 by SAE International in United States
This SAE Recommended Practice describes an empirical method for determining the theoretical ash content of aviation piston engine lubricating oils by calculating the equivalent weight of metallic oxides formed at 775 °C based on the metallic elemental concentration. The calculation method of ash determination may be used as an alternate to ASTM D 482 for application to the standards for aviation piston engine lubricating oils. Field of Application This procedure is recommended for use in the qualification, manufacturing, and quality assurance testing of aviation piston engine lubricating oils where the ash content is limited to a maximum of 0.011%. Background The ash content as measured by ASTM D 482 has very poor precision and repeatability for lubricants having low ash content. The precision statement for the method states that the reproducibility of a sample in the range of 0.001 to 0.079% ash content is 0.005%. Further, the bias of the test cannot be determined and there is no standard reference material containing a known level of ash for this method. This poor precision has led…
