Properties of Canadian re-refined base oils

The Fuels and Lubricants Laboratory of NRC (Canada) has been examining for over 10 years, as a service, the properties of base stocks made by Canadian re-refiners. Nineteen samples of acid/clay processed base stocks from six Canadian re-refiners were examined. When well re-refined, the base stocks have excellent properties including a good response to anti-oxidants and a high degree of cleanliness. Since traces of additives and/or polar compounds do remain, the quality of the base stocks is judged to be slightly inferior to that of comparable virgin refined base stocks. Some suggested specification limits for various properties and some indication of batch-to-batch consistency were obtained. Any usage of the limits should be done with caution, e.g., sulfur, bearing in mind the rapidly changing crude oil picture and engine and machine technology leading to oil products of differing compositions. Certainly modifications are in order; it may even be desirable to have grades of base stocks.
