Q & A: Are We There Yet?

The ultimate engine oil question. . .


Wear protection is another key benefit of CJ-4 motor oil. Based on extensive industry recognized engine wear tests done by Shell Lubricants, Shell Rotella® T motor oil with Triple Protection™ technology provides on average 50 percent greater wear protection (ranging from 27 percent to 88 percent reduced wear) than the previous formulation.

In pre-2007 engines, CJ-4 oil will provide the latest technology in engine protection. Switching your entire fleet to CJ-4 motor oil will avoid the need to stock more than one oil and confusion about which oil is the correct one to use, potentially avoiding warranty issues that could result from using the improper motor oil in a 2007 or newer engine.
