Chevron announced its Delo 400 LE SAE 15W-40 has met the Society of Automotive Engineers of Japan's automotive diesel engine oil standard, JASO DH-2.

"Japanese-manufactured diesel trucks and engines have become increasingly popular in the United States," said Nicole Fujishige, indirect channel marketing manager, Chevron Products Company. "Due to the growing popularity of these medium- and heavy-duty engines, we felt our flagship Delo 400 LE 15W-40 needed to meet this standard. By meeting JASO DH-2, our customers can now carry a single oil that meets the varying OEM and industry specifications they face."

The DH-2 classification applies to Japanese-made diesel engines with aftertreatment devices, such as diesel particulate filters (DPFs) and catalysts that comply with up-to-date exhaust emission regulations. DH-2 oils, like Delo 400 LE SAE 15W-40, are ideal for the medium- and heavy-duty engines built by manufacturers like Hino Motors Ltd., Isuzu Motors Ltd., Mitsubishi Fuso Truck & Bus Corp. and Nissan Diesel Motor Co. Ltd.

The heavy-duty motor oil is formulated for new low emission engines running on ultra low sulfur diesel fuel and is also backward-compatible with earlier API oil service categories.

Delo 400 already meets or exceeds all major API, ACEA and diesel engine manufacturer's requirements.

The oil keeps rings clean and free for better combustion pressure and to provide minimal wear. It reduces valve and piston crown land deposits, thus lowering oil consumption. Its high level of ashless dispersants keeps fuel soot in suspension, helping to avoid filter plugging, heavy cylinder head sludge, abrasive polishing wear, high viscosity increase, and oil gelling. These problems can result in excessive engine wear and bearing failure on startup, without prior indication to the operator.

Delo 400 LE SAE 15W-40 is available in gallon jugs, 5-gallon pails, 55-gallon drums and in bulk.
