Method for packaging engine oil added with fuel lubrication with petrol engine of vehicle, involves packaging oil added with fuel when final quantity of additive and fuel is higher than threshold quantity of additive and fuel in oil

摘要

The method involves ageing (S4) contents (MIX) of a reactor (1) during given ageing duration (FD) and at given ageing temperature (TV). The ageing of the contents of the reactor is controlled (S5) by measuring characteristics of ageing of contents of an engine. Engine oil (HL) added with fuel (BC) is correctly packaged when final quantity of additive is higher than quantity additive of a threshold (Sad) in the engine oil, and final quantity of the fuel is higher than of the threshold fuel quantity (Sbc) in the engine oil. The additive of acceleration of the ageing of the engine oil is the additive selected from a group consisting of metallic oxides, hydroperoxides, agents of nitro-oxidation and iron acethylacetonate.
