There is a new generation of heavy duty engine oils. The National Highway Traffic Safety Administration (NHTSA), Environmental Protection Agency (EPA), and major engine manufacturers have put into place new objectives around medium and heavy-duty vehicles fuel economy and emissions. To meet these goals as well as secure proper engine protection, new generations of diesel engine oils have been rolled out.
The new PC-11 (Proposed Category 11) Heavy Duty Engine Oils (HDEO), now called CK-4 and FA-4 will surpass current CJ-4 oil technology. What is the difference you ask? Many next-generations engines will require being run at a higher temperature while operating in order to meet the requirements of releasing fewer emissions. This is where PC-11 comes in.
We know what you’re thinking – how does it impact us? When it comes to transportation companies, this new standard will provide the opportunity to cut operating costs and reduce fuel consumption. Other benefits such as reduced wear and deposits on engines will help minimize maintenance costs and downtime. A shift in oils can allow fleet owners to see a significant fuel economy savings while giving drivers confidence and peace of mind that the product they are now using has gone through severe testing for performance engine protection.
CK-4 and FA-4 oils will have to pass the seven existing CJ-4 tests for licensing qualification. In addition, there will be two new tests added measuring improved oxidation and aeration. These two new tests will indicate the oil’s ability to provide fuel economy benefits and enhanced engine protection – things that are not currently measures as there are no specific fuel economy tests.
For transportation companies throughout out the United States, this change has already been a positive one. Although there is an initial adjustment to the types of oils that need to be used to keep fleets in tip top shape, there is a long term cost benefit as well as the ability to minimize their greenhouse emissions.
