Engine Oil Additives

Heavy-Duty Engine Oils

Heavy-dutyLubricants used in “on-highway” and “off-highway” heavy-duty vehicle applications are classified as Heavy Duty Engine Oils. These products are often highly specialized due to the extreme environments in which they operate, geographic-specific emission regulations, available fuel grades and subsequent OEM engineering requirements.

Applicable additive systems often need to simultaneously address multiple performance attributes such as high heat/heavy soot, after-treatment devices, fuel economy and wear. In emerging market areas, a significant number of lubricants are used in mixed fleet applications. Lubrizol has a comprehensive product line meeting the full range of performance requirements worldwide.
