Abstract

Oxidation resistance is one of the limiting factors for long drains, bionotox, LowSAP or NoSAP engine oils. The French iron catalyzed oxidation test (ICOT) uses 60 ppm iron acetylacetonate as diluted catalyst under an aeration of 10 L∕h at 170°C. The ICOT ranks the oxidation stability of oils according to three properties: a. the viscosity increase (e.g., max. Δη^40°C<100 % or Δη^100°C<100 %), b. the increase to an individual TAN (e.g., max. 7.5 mgKOH∕g) and c. the oxidative evaporation losses of max. 10 % at Δη=100 % due to oxidation. This paper describes the ICOT method standardized as GFC Lu 36T 03 and the obtainable accuracy. Also, results are compiled achieved with this test for factory fill engine oils as well as alternative prototype engine oils based on esters, blends of esters with hydrocarbons, and polyglycols.
