www.CJ-4.com provides ALL the information you need about the latest diesel engine category, API CJ-4. Details given in the website include why API CJ-4 was developed and how this specification is different from pervious diesel engine categories. Emission regulation is the key driver changing heavy duty engine design and operation. CJ-4 engine oils are required to provide the necessary protection and performance.
A CJ-4 online sales course is included on the website at http://www.lubrizol.com/CJ-4Course/. In this simulation course, you learn about CJ-4 by helping a fleet manager plan for new CJ-4 trucks! The course also provides excellent reference information on after-treatment devices, emissions, fuel changes, vehicle design changes, and lubricants.
