Heavy duty diesel engine oil additives are designed to protect and enhance the performance of heavy duty diesel engines operating over the road or in off-highway applications such as mining and construction. The Infineum D series can be used to formulate lubricants across the full range of engine performance requirements, up to and including the latest American Petroleum Institute (API), Association des Constructeurs Européens d’Automobiles (ACEA), Japan Automobile Manufacturers Society (JAMA) and original equipment manufacturer (OEM) specifications. When combined with Infineum’s pour point depressant, viscosity modifier and supplemental engine oil additives, formulations with the Infineum D series can deliver unique performance requirements in a wide array of base stocks.
The current API CJ-4 specification was developed to meet the increased demands of new lower emission diesel engines equipped with exhaust gas recirculation (EGR) and diesel particulate filters (DPFs). These engines generate hydrocarbon soot particles that can combine into sticky masses and increase engine oil viscosity. Infineum’s distinctive soot dispersing chemistry for API CJ-4 is built into the detergent inhibitor (DI) package and prevents soot particles from fusing together. By thwarting excessive viscosity increase, this particle suspension formula allows the potential for oil drain intervals beyond current performance levels.
TECHNOLOGY HIGHLIGHT: Infineum D3470 Series
With the Infineum D3470 Series, engine oils are supported by a technology platform with unprecedented experience: 25 years and 2.5 trillion field miles in the making. Incorporating Infineum’s proprietary soot-busting dispersant chemistry, this proven performer controls soot-related viscosity increase and improves low temperature pumping capability, all while maintaining a high 10 TBN to support longer oil drain intervals.
