Shell Rotella has created a website to explain PC-11.
WhatisPC11.com is intended to explain the API proposed category change coming in 2017 and designed as a resource for fleets, owner/operators and anyone driving a diesel powered pickup truck or operating equipment.
“With two subcategories [both backward compatible to older engines and also work with upcoming designs] 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.
Improved fuel economy and lower emissions challenge the nine-year-old current category with regulations calling for thinner, cooler-running oil.
