Abstract

The present invention relates to a method of and a corresponding system for reducing fuel consumption and environmental impact in a two-stroke engine, comprising the steps of obtaining system oil/consumable system oil (301') from at least one engine (300), adding (102) at least one friction modifier (101) to at least a part of the obtained system oil/consumable system oil (301'), where the addition of the at least one friction modifier (101) reduces the friction coefficient of the obtained system oil/consumable system oil (301'), resulting in a system oil/consumable system oil with reduced friction (301"), and supplying said system oil/consumable system oil with reduced friction (301") to said at least one engine (300). In this way, frictional losses caused by contamination of the system oil/consumable system oil are avoided or minimised, which normally take place as the oil is used and which would otherwise cause a continuous decrease in engine efficiency resulting in increased fuel consumption and emissions. In addition, the present invention related to a method and a corresponding system to convert system oil/consumable system oil into cylinder oil. Finally, the present invention relates to a method to use a consumable system oil as it is being converted into cylinder oil. This furthermore allows for the consumable system oil to contain a lower performance additive package and/or additive treat rate. Thus great economical savings and environmental improvements are achieved.
