CLS™ Development Series: Transportation

Facilitated 6 week online transportation program

Language Session

Prerequisite: Participants must have access to The Lubrication Engineers Manual, 2nd Edition

Stop sweating the CLS exam!
Lubrizol K2M in cooperation with the STLE has developed a series of seven online programs to help you.

The Transportation Lubrication Program is a 6 week program designed to reinforce your knowledge of the fundamentals of how engines work. This program speaks to small engines and explains the API system and the two current categories CI-4 and CJ-4. It covers the specifics of passenger car motor oil applications and the specific attributes of diesel engine oils in particular applications.
