SAN RAMON, Cal. –Chevron has announced its Delo line of engine oils, lubricants and coolants are well-tested and fully-compliant with EPA2010 engines.

The company says it has been testing its products in nearly 24 Volvo D12C engines using diesel particulate filters (DPF) and selective catalytic reduction (SCR) aftertreatment systems since 2000, without any problems.

Chevron says its Delo 400 LE SAE15W-40 demonstated excellent durability, reliability and reduced production of incombustible materials within the DPF. In many cases, engines have racked up between 130,000 and 190,000 miles in testing while using Delo engine oil and with drain intervals of 30,000-40,000 miles, Delo 400 LE 15W-40 still resulted in excellent engine durability and low levels of wear, Chevron announced.

Chevron also found its CJ-4 product resulted in less incombustibles in the DPF than its API CI-4 Plus oil of the same grade, which should extend DPF cleaning intervals and potentially improve fuel economy due to a reduction in backpressure on the exhaust.

“To assure our customers have lubricants they can rely on to run their businesses and protect their investments, we conduct extensive field and laboratory tests,” said Jim McGeehan, global manager, diesel engine oil technology with Chevron Global Lubricants. “In preparation for 2010, we have tested for nearly a decade. Our customers can rest assured that our Delo 400 LE 15W-40 will provide the protection needed in 2010 and pre-2010 engine technologies.”
