Shell Rotella T meets CJ-4 specs
By Sean Kelley
Shell Lubricants announced June 21 that a
re-formulated Rotella T motor oil will meets all of the specification criteria for the new API CJ-4 service category for diesel motor oil.
The company will make the new oil, designed to work with 2007 on-highway engines, available in bulk and drums July 1 and by quart, gallon or pail Oct. 15.
New lower-emission diesel engines will require an engine oil with different characteristics than is currently available. The new formulation is backwards compatible with pre-2007 engines and can be mixed with CI-4 oils currently on the market.
CJ-4 oils must meet more stringent requirements than previous oil; they must be able to handle higher engine temperatures and higher levels of soot while
using new detergent packages that rely on less phosphorus, sulfated ash and sulfur, says Dan Arcy, technical marketing manager for Shell Lubricants. CJ-4 oils “also helps maximize the durability of Diesel Particulate Filters,” Arcy says. Engine OEMs are deploying DPFs to trap emission particles.
The new Rotella T motor oil has also met the specification requirements for Caterpillar ECF-3 and Detroit Diesel 93K218 and has gained Cummins CES 20081, Mack EO-O Premium Plus 2007 and Volvo VDS-4 approvals.
Shell will continue to make its API CI-4 Plus Shell Rotella T motor oils available in bulk and drums beyond the introduction of the new CJ-4 formula to meet customer demand. For large fleets, Shell will also market Rimula Super, which also meets the CJ-4 standard.
