SL
Oils with API SL approval (specification) (engine oils for engines of machines produced after 2000)
According to the requirements of car manufacturers, oils of this class are used in multi-valve, turbocharged engines that operate on lean fuel mixtures. Olives meet today's increased requirements for ecology, as well as energy saving.
Oils that meet the requirements of API SL can be used in cases where the class is recommended by the car manufacturer SJ or earlier.
