Shell Rotella’s new WhatisPC11.com site profiles the next generation of diesel engine oils known as American Petroleum Institute (API) Proposed Category 11 (PC-11), covering product fundamentals, impending changes, testing updates, and how the specification is expected to affect new, current and older engines when PC-11 replaces API CJ-4 engine oils by 2017. The site also explores diesel engine technology changes, driven by tightening emissions regulations, and how Shell Lubricants is approaching the Rotella PC-11 series.
