Since 1923, Purolator has been developing oil filtration products to remove contaminants and meets all SAE and ISO testing standards. Today’s EGR (Exhaust Gas Recirculation) engines help reduce NOx emissions, but can reintroduce soot to the combustion process compromising lubricating oil quality. Purolator Heavy Duty offers standard, high efficiency and extended service oil filters that are tested to ISO 4548 standards.
While extended service intervals may save money in the short run, it is important to remember that improperly managed oil change intervals can lead to accelerated engine wear and costly engine rebuilds. Regular scheduled oil analysis should be used to help determine your equipment’s service interval. Oil analysis provides valuable information on the contaminant and physical properties of an engine’s oil.
The Purolator Heavy Duty oil filter line includes: Spin-On Filters and Cartridge Filters.
