What PC-11 means for lubricant end-users

Chevron's Len Badal presents at MATS 2015

We’ve discussed the upcoming Proposed Category 11 (PC-11) at length on Delo Lube Matters. Our two blogs on the subject examine the creation of the specification, as well as how the new split category will be implemented. Last week, at the Mid-America Trucking Show (MATS), we had the opportunity to discuss PC-11 in a presentation seminar. In addition to hearing the latest from people on the ground, we shared the latest updates on this important category upgrade that will have a unique impact on the heavy duty motor oil (HDMO) landscape.

PC-11 is being developed with the following factors in mind:

  • To help OEMs improve fuel economy and reduce CO2 emissions
  • To provide improved engine protection with the use of lower viscosity HDMOs
  • To maintain protection of emission systems with Diesel Particulate Filters and Selective Catalytic Reduction
  • To improve performance under high temperature engine operation

Since our last update, we’ve learned of these proposals for the new categories:

  • PC-11A, which will be licensed as API CK-4, will retain historical limits for high-temperature, high-shear (HTHS) viscosity and will be backward compatible with previous generation API “C” categories.
  • PC-11B, which will be licensed as API FA-4, will have an HTHS viscosity between 2.9 and 3.2 mm2/sec and will not be backward compatible with previous generation API “C” categories. API FA-4 oils are being developed for new model year 2017 engines for OEMs seeking to achieve improved fuel economy and to comply with new regulations for control of greenhouse gas emissions. Oils meeting API FA-4 will incorporate an “L” after the viscosity grade—for example: SAE 10W-30 L and SAE 5W-30 L—to help further distinguish them from higher viscosity oils, since these oils may not be recommended for use in all engines and applications.

An important part of this category will be for end-users to be more knowledgeable about their equipment and oil than for past categories. Knowing the recommended oils for a given engine and vehicle will be essential given the new split category. Properly understanding these new developments will help users to make the best decisions for their fleets, and take full advantage of advances in performance, wear and oxidation protection, and fuel economy.

    I have some older engines on the farm. Been a delo user for years. What 15 -40 should I be using to protect these engines?
