Fuel economy and new engine oils
Engine oil makers weigh in on the new oil formulations to help meet EPA improved fuel economy standards.
New heavy-duty engine oil categories are driven by regulation
When the U.S. Environmental Protection Agency (EPA) and National Highway Traffic Safety Administration (NHTSA) announced regulations in 2010 designed to reduce greenhouse gas (GHG) emissions and mandate fuel economy improvements for heavy-duty engines and vehicles, it set in motion a change to engine oil specifications. In turn, the Engine Manufacturers Association (EMA) requested that the
Three things to know about the new engine oil categories
By now, you’ve probably heard about the new heavy-duty engine oil categories that will replace the CJ-4 oils come December 1st. The first category, API CK-4 will be compatible with all engines and offer increased efficiency over the old CJ-4 category. The new category – API FA-4 – offers additional efficiency gains in 2017 model year engines,
The skinny on low-viscosity oils
The North American Council for Freight Efficiency (NACFE) has released its Confidence Report on low-viscosity oils. It begins with the premise that truck engine mechanical losses occur from pumping and friction and consume approximately 16% of the total energy input of the vehicle. Lower-viscosity oils (those with less internal resistance to flow) will reduce these
Three new ways oils will be identified and utilized
This December we get a little extra bonus: Three changes in the way lube oils are identified and utilized. First, the API will discontinue the use of the term “energy conserving” on their SL and SM passenger car motor oils (PCMO). The term is discontinued because the engine parts needed to run the laboratory engine
What will be the impact of PC-11’s second category?
I just returned from making a presentation at the Advanced Engineering Technology Conference (AETC) associated with the Performance Racing Industry (PRI) show in Indianapolis. This is the biggest event in the world for people who earn their livings racing. The general public is not allowed to attend. There I found that even racers and race engine
Kenworth tours the U.S. with Capitol Christmas Tree (Photo gallery)

New Frontier: The changing market of on-highway fleets
The market is changing. Vertical integration has meant fewer choices when spec’ing trailers, but has also in some ways made things more complicated.
PC-11 update
Engine dynamometer tests needed to define the new PC-11 performance category are now finalized. However, the new PC-11 performance level will force end users, engine manufacturers and oil marketers to become familiar with two new (and not interchangeable) heavy-duty diesel engine oils. When the Engine Manufacturers Association (EMA), reacting to the EPA’s call for reduced
