HOUSTON, Texas — Shell ROTELLA T with Triple Protection technology heavy-duty motor oil has met new Caterpillar specifications, ECF-1-a, ECF-2 for pre-2007 on- and off-highway diesel engines, according to company officials. As previously announced, Shell ROTELLA T with Triple Protection also meets Caterpillar specification ECF-3 for the latest 2007-compliant engines fitted with diesel particulate filters (DPF) that use diesel fuel with less than 15 parts per million sulfur.

Shell ROTELLA T with Triple Protection may be used by operators of 2007 and pre-2007 Caterpillar on- and off-highway vehicles, equipment and machinery that require ECF-1-a, ECF-2 or ECF-3 motor oils, said Dan Arcy, technical marketing manager for Shell Lubricants. It is now possible to stock a single motor oil for one of the worlds largest manufacturers of heavy-duty off-highway equipment and leading supplier of on-highway truck engines.

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 March 1.
