Passenger Car Motor Oil Additives

Passenger car engine oils (also called 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. PCMO's use friction modifiers and lower viscosity grades to contribute to fuel economy while controlling deposit levels, minimizing wear, and reducing catalyst degradation. 

Performance Advantages

MCC provides PCMO products based on Chevron Oronite’s technology; products range from fully licensable AP GF5/SN PCMO Dexos 1 Gen 2 additives to economical additives used in older engines and for export.

Advantages include:

• Combination of superior deposit control additives and unique friction modifier chemistry which provides the performance to balance the demands of improved engine cleanliness and fuel economy

• Friction modifiers (FM's) with class leading fuel economy performance

• Unique multifunctional oxidation and wear inhibition chemistry with exceptional wear protection, even at very low phosphorus levels

• Chlorine-free dispersant chemistry providing superior deposit control and fuel economy

• A wide range of detergent chemistries that provide superior high temperature deposit control

• High performance viscosity modifier chemistry, meeting a wide range of applications with class leading thickening efficiency

ILSAC GF-6 

ILSAC GF-6 is the latest in a series of PCMO performance requirements from GF-5 through API SN Plus and now GF-6, aimed at going beyone mitigation of LSPI to further increase fuel economy, enhance oil longevity and improve wear protection and emissions control.

API SN Plus

API SN Plus is a proposed supplemental standard to the API SN specification, which will introduce oils for LSPI (Low Speed Pre-ignition--click here to learn more about LSPI and how to prevent it) mitigation. The designation for this supplement will not impact ILSAC GF-5 or the API Certification Symbol ("Starburst").
