TECHNOL PHOENIX 10W-40 is especially suitable for engines used in on-road trucks, and busses and also trucks used for off-road activities (quarries, construction, mining, and railroad) that require API CK-4 or CJ-4 level. This engine oil withstands very long working periods under severe conditions, such as high load, heat and dust. It is recommended for engines with exhaust gas aftertreatment systems meeting Euro Stage V standard (or US EPA Tier 4F) and for on-road, Euro 6 and previous generation of engines of American, European, and Japanese manufacturers. Thanks to its specific Low SAPS technology (low content in Sulphated Ash, Phosphorus, and Sulphur), this engine oil is designed for the latest diesel engines equipped with post-treatment systems, such as diesel particulate filters (DPF) or DENOX catalysts.
