CASE No. 1 CJ-4 Engine Oil for Whole-Fleet Application

Today’s ultra-low sulphur diesel fuel and emissions systems that recirculate exhaust gas have placed new demands on diesel engine oil. Additives to handle high-sulfur loads and the resulting acids are no longer needed. What is needed today are additives that stand up to Tier 4 emissions requirements and higher combustion temperatures.

A new API diesel engine oil classification, CJ-4, was developed to meet these new demands. As a result, the new No. 1 15W40 and synthetic blend SBL 10W40 engine oils from CASE now carry the CJ-4 rating. CJ-4 engine oils can be used in all diesel vehicles, including pickups and heavy-duty trucks, requiring CJ-4 oil, as well as all CASE Construction engines.

This means that No. 1 engine oil from CASE can be stocked as the sole diesel engine oil for mixed fleets, regardless of their emissions equipment.

The qualities of the new No. 1 oil are especially well suited to CASE engines that meet Tier 4A/B requirements. Specifically, the oil has greater capacity to stand up to higher heat and to maintain its lubricity in the absence of the sulphur that entered oil when higher sulphur fuels were used.

The new No. 1 CJ-4 oils are a good choice for owners who want to take advantage of the 600-hour oil change intervals now possible with select CASE engines, according to the company.

It is also a “backwards compatible” oil, meaning it’s suitable for use in nearly all older diesel-powered equipment that is now consuming ultra-low sulphur fuel at 15 ppm. This meets the requirement for off-highway vehicle use in the U.S. and Canada since late 2010.
