HOUSTON, TX – Shell Lubricants has announced that Shell ROTELLA T with Triple Protection technology heavy-duty motor oil meets new Caterpillar specifications, ECF-1-a, ECF-2 for pre-2007 on- and off-highway diesel engines. Shell ROTELLA T with Triple Protection also meets Caterpillar specification ECF-3 for the latest 2007-compliant engines fitted with diesel particulate filters that use diesel fuel with less than 15 parts per million sulfur.

Shell ROTELLA T with Triple Protection provides enhanced engine protection, cleanliness and compatibility with exhaust after-treatment devices such as diesel particulate filters (DPF). The advanced formulation meets the latest API CJ-4 specifications for heavy-duty diesel engine oils and the latest engine builder specifications.

The Caterpillar ECF-1-a specification replaces the existing ECF-1 specification. ECF-2 is a new higher performance specification and requires performance demonstration in a 500-hour C-13 engine test. The specification has been designed to provide optimal protection and performance of 2006-model year and older on- and off-highway equipment that use Cat 3500 Series and smaller commercial and machine diesel engines. Both specifications become effective Mar. 1, 2007.
