Shell Lubricants says its Rotella T heavy-duty motor oil meets Caterpillar's ECF-1-a and ECF-2 specifications for 2006 and earlier on/off-highway diesels, as well as the ECF-3 spec for the latest 2007 compliant engines fitted with diesel particulate filters that use ultra-low-sulfur diesel fuel. The new formulation, representing the largest advance in Shell's engine oil technology in 30 years, also meets the latest API CJ-4 specs, Shell said. Lab tests show that it provides 27 to 88 percent less wear than the previous formulation and, in 10.5 million miles of highway testing, it's shown to significantly lower iron wear.
