Additional information
This product was developed for the purpose of suppressing pre-ignition (abnormal combustion) that can occur in downsized turbo gasoline engines.
the engine has been downsized and equipped with a supercharger to operate from a low rotation range in order to obtain the same power as a conventional engine in response to the demands of the times for reducing co2 emissions and improving fuel efficiency..
it is in the low speed range under such high load conditions that the possibility of abnormal combustion is feared, and one of the causes is related to the components contained in the engine oil.
in consideration of these factors, we designed the blending balance of functional additives exclusively for lspi, and optimized the molecular weight distribution of the base oil to suppress the oil going up into the combustion chamber.
