Ensures optimal functioning of three-way catalytic converters and particulate filters, which lower emissions of NOx, CO2, CO and particles and ensure compliance with performance levels announced by manufacturers and Euro V environmental standards. Extends the service life of post-treatment systems by preventing DPFs and three-way catalytic converters from clogging and filling. Excellent resistance to temperature variations guarantees the longevity of engine parts and optimal performance level under all circumstances. Satisfies the most demanding manufacturer service plans by permitting extra-long oil change intervals.
