heavy duty motor oils

Oronite delivers highly effective lubricant additive technology for heavy duty diesel engines. We have a long list of firsts in diesel engine lubrication starting with our invention of detergent additives in the early 1930s. We are constantly adapting and optimizing diesel engine lubricant additive technology to meet original equipment manufacturer (OEM) and customer requirements. And the results are reduced wear and viscosity changes related to soot, reduced ring sticking and excessive deposits in the ring belt, minimal downtime for equipment and vehicles, and an increase in engine life.


Oronite's strong relationship with major engine manufacturers provides early access to evolving engine technologies, allowing us to deliver high-performance component packages that meet our customers’ future needs. Our HDMO additive products are extensively field tested in a wide range of engines and service to help ensure proven, high performance.

Oronite’s latest HDMO additive packages offer you the benefits of a universal oil to help simplify your logistics without sacrificing wear protection. The API CK-4, FA-4 and ACEA E- and F-category additive packages feature our FrictionRelease™ friction modifier component designed specifically for heavy duty motor oils. 

Chevron Oronite's CK-4/FA-4 additive packages provide performance benefits in both on- and off-road applications. They also deliver on the promise of a universal oil, meaning owners with a mixed fleet of light- and heavy-duty diesel vehicles can enjoy simplified logistics, increased flexibility and the durability demanded in heavy-duty field applications.


Our formulations have also focused on fuel efficiency. Through our new FrictionRelease friction modifier component, we can help enhance fuel economy benefits beyond reducing viscosity.

OLOA 61105, 61106, 61107 are available and went through a robust qualification process including rigorous testing in laboratory and real-world environments. These products offer a high-performing, flexible solution that meet API CK-4, FA-4, API SN, ACEA E6/E9-12, and multiple global OEM claims.

OLOA 61011 provides formulation flexibility for your blending needs. This top tier additive package can blend low and high temperature/high shear (HTHS) oils suitable for heavy-duty and light-duty commercial vehicles meeting Euro V and Euro VI emissions requirements and a broad range of off-road applications for vehicles meeting EU stage IIIA, IIIB and IV and U.S. Tier 4 emissions standards.

OLOA 61005 is a top tier heavy duty additive package for trucks meeting Euro IV & V emission standards, with or without after treatment systems. It is also backward compatible with older generations of trucks meeting Euro I, II & III.


OLOA 61005 was specifically formulated to cover the well-established SAE 10W-40 grade and also the growing SAE 10W-30 segment. 

OLOA 61530/61519 - These additive packages provide value and flexibility to lubricant manufacturers for their heavy-duty needs, helping them reduce emissions and improve fuel efficiency without compromising engine durability.  They are adapted for mixed fleets and off-road vehicles in construction, agriculture, quarries, and mining meeting Euro IV stage emission norms.

Chevron Oronite’s extensive heavy duty engine oil main cascade, composed of 4 additive packages.


OLOA 59880 is a heavy duty engine oil package designed to cover Euro IV equipment and earlier and recommended for both on road and off road equipment.


OLOA 59770 is a flexible high performance additive suitable for Euro IV diesel engines and recommended for off-road and extensive on-road equipment also covering passenger car applications.


OLOA 59766 is an optimized and cost-effective package for general applications suitable for Euro III and IV engines and particularly adapted for busses and trucks.


OLOA 59762 is an economic additive package suitable for Euro II and Euro III engines appropriate for busses, trucks and off-road equipment.


The cascade allows you to blend a large range of finished oil for multiple applications. With treat rate cascade or few boosters, it is possible to link the economic profiles to an optimized package and to a high-performance lubricant. With one or two packages, you have the possibility to design a complete range of lubricants for heavy-duty engines and also for passenger cars, high tier trucks, and stationary engines.
