Passenger car motor oils (PCMO) must provide engine protection under a wide variety of conditions, ranging from low-temperature, short-trip service to extended high-speed, high-temperature operations. PCMOs use friction modifiers and lower viscosity grades to contribute to fuel economy while controlling deposit levels, minimizing wear and reducing catalyst degradation.

Our customers trust us to help provide value and flexibility for their PCMO businesses – whether it’s helping meet the latest industry or original equipment manufacturer (OEM) specifications or preparing for a smooth transition to the next one.

At regular intervals, a new service category is placed on engine oils because auto manufacturers are under constant pressure to reduce emissions, provide engine protection and increase fuel economy. In every region where we operate, passenger car motor oils (PCMO) are evaluated against specifications of independent organizations such as American Petroleum Institute (API), International Lubricants Standardization and Approval Committee (ILSAC), Japanese Automotive Standards Organization (JASO) or the European Automobile Manufacturers Association (Association des Constructeurs Européens d'Automobiles, ACEA) and original equipment manufacturers (OEMs) standards including General Motors (GM), Daimler, Bavarian Motor Works (BMW) or Volkswagen (VW).

shedding light on LSPI

Demand for improved fuel economy and reduced emissions has driven passenger car manufacturers to design downsized, turbocharged engines. While these engines provide higher power density and improved efficiency, they are also prone to low speed pre-ignition (LSPI).

OLOA 54720 additive package

OLOA 54720 offers simplified logistics and addresses the latest, most demanding OEM requirements. This one product addresses a wide range of SAE 0W-20 OEM claims, such as BMW LL17FE+, MB229.71 and Volvo RBS0-2AE 0W-20. OLOA 54720 is one of the first low viscosity SAE 0W-20 additive packages to provide low speed pre-ignition (LSPI) protection. It passes stringent LSPI tests, including those from Daimler, API and Opel, helping prevent severe engine damage caused by LSPI. As such the product is also designed to anticipate future changes as ACEA aims to include LSPI testing in upcoming categories.

In an attempt to reduce emissions, car manufacturers have downsized engines and equipped them with turbochargers to maintain drivability. These conditions cause oils to degrade sooner, to thicken faster, and makes them more prone to form deposits. OLOA 54720 helps keep the engine clean and provides turbocharger protection in these tough conditions.

Fuel economy gains are enabled by new engine designs incorporating several technologies that make them more efficient, such as direct injection. While lowering viscosity for fuel economy reasons, our formulators were able to maintain the durability and cleanliness performance that is important for European OEM’s. Car makers are increasingly requiring SAE 0W-20 synthetic oils with low viscosity and low friction, to help improve fuel economy and deliver high performance.

field testing in PCMO

Oronite is constantly looking to provide innovative and field-proven passenger car motor oil (PCMO) technology. With increasing demands on lubricants, future engine oils will need to address a broad range of performance criteria. Our field testing program is one way of demonstrating how Oronite’s PCMO technology can stand up against real-world conditions.
