The Shell Rotella brand has launched a new website called WhatisPC11.com to help educate and inform people about the next generation of diesel engine oils known as API Proposed Category 11 (PC-11). Shell Rotella created the website to be a resource for topics such as the fundamentals of PC-11, impending changes, testing updates, and how it is expected to affect new, current and older engines when the category replaces API CJ-4 engine oils by 2017.
WhatisPC11.com shares the journey of the creation of PC-11, why a new oil standard is necessary, and how new lower viscosity oils are being developed. Unlike past categories that are backward compatible with the previous category, the new category will have two subcategories, one that is backward compatible to older engines and one that will work with upcoming engine designs. Therefore, education about both oils will be vitally important to ensure seamless integration for every industry affected by this change.
“With two subcategories and new engine hardware tests, there will be lots of questions about how the oils will be formulated and which oil should be used for different applications,” said Dan Arcy, OEM technical manager for Shell Lubricants. “As we formulate and test the new oils, Shell Lubricants can offer valuable resources to those operating diesel engines both on- and off-highway to support them through the transition over the next few years.”
WhatisPC11.com will cover the following topics and more:
• Why a new engine oil specification is needed
• How the two subcategories are different and will be distinguished in the marketplace
• What PC-11 will mean for fleets, owner/operators, construction, agriculture and diesel pickup trucks
• Changes to diesel engine technology
• The type of testing done to make PC-11 a reality
• How Shell Lubricants is developing its new Shell Rotella PC-11 heavy duty engine oils
PC-11 Background
The new API PC-11 category is being driven by changes in engine technology to meet emissions, renewable fuel and fuel economy standards for reduced CO2 and other greenhouse gas emissions. In addition, changes in engine hardware and operating conditions that better represent new engine technology in the marketplace since the last heavy-duty engine oil category was introduced in 2006. Several engine tests need upgrading and older test hardware is expected to become unavailable. When the new PC-11 is first licensable, it will have been almost 10 years since the current category was introduced.
