Motor oil specification (Mitsubishi Lancer 3)

In principle, only HD oils are approved for modern engines. HD oils are alloyed oils whose lubricating properties are significantly improved by adding various chemically active substances. These additives provide better anti-corrosion protection, better oxidation resistance, especially a reduced tendency to form deposits in the crankcase, improved viscosity stabilization properties, cleaning and dissolving properties. Cleaning and dissolving additives not only reduce the formation of deposits in the engine, but also have the ability to dissolve deposits and other contaminants in the engine, separate and hold them in a suspended state, which makes it possible to drain all contaminants when changing the oil. The grade of HD oil is determined by the API system (API American Petroleum Institut) European manufacturers also adhere to this system.

The designation consists of two letters. The first letter characterizes the range of application: S = Service, intended for gasoline engines, C = Commercial, intended for diesel engines. The second letter designates the grade in alphabetical order.

The highest grade oils according to API specification are SG for gasoline engines and CE for diesel engines.

Note: Motor oils that are clearly indicated by the manufacturer for use in diesel engines are prohibited for use in petrol engines. There are oils that can be used in both petrol and diesel engines. In this case, a double designation is indicated on the packaging (e.g. SF/CD).

The following API specification oils are suitable for MITSUBISHI COLT/LANCER with gasoline engines: SE, SF and SG, and for diesel engines: CC, CD and CE.
