ConocoPhillips Co., the fourth largest U.S. lubricants supplier, announced today, Aug. 8, that Guardol ECT (Emissions Compatible Technology), a new premium synthetic blend diesel engine oil, has passed the American Petroleum Institute’s latest API CJ-4 standard for diesel engine lubricants. This new offering was created specially to meet the U.S. engine manufacturers’ lubrication requirements for the new 2007 low-emissions engines equipped with exhaust after-treatment devices.

“Guardol ECT will also provide enhanced performance and protection for older engines requiring service under the previous specifications,” says Reginald Dias, director of commercial products for Houston-based ConocoPhillips Lubricants. The new product will be available to ConocoPhillips customers who purchase products under the Conoco, Phillips 66 and 76 Lubricants brands starting early fall 2006.

“We have passed all CJ-4 engine tests with excellent results ensuring that Guardol ECT will provide total protection for the new engines designed to meet the U. S. Environmental Protection Agency’s 2007 on-highway truck exhaust emissions regulations,” Dias says. “In order to illustrate the product’s performance, we have also accumulated extensive on-road equipment field experience using the ultra-low-sulfur diesel and today’s S500 diesel fuel.

“Further, we have made it a priority to offer customers a state-of-the-art synthetic blend formulation by combining the unique benefits of ConocoPhillips Lubricants’ proprietary additive technology with superior quality Group II and synthetic base stocks,” Dias says. “Built on the proven drain capabilities and performance benefits of our QLT technology and the advanced properties of synthetic base stocks, the new formulation will offer better oxidation resistance, thermal stability, film strength and more advanced low temperature properties relative to nonsynthetic-blend engine oil.”

Guardol ECT is backward-serviceable for engine protection in pre-2007 engines specifying lubrication service under the previous categories and meets the performance requirements of both API CJ-4 and CI-4/CI-4 Plus specifications, the company says.

In conjunction with Guardol ECT, ConocoPhillips Lubricants also announced the introduction of Fleet Supreme EC (Emissions Compatible) diesel engine oil, which it says is compliant with the API CJ-4 specification and meets the engine builders’ 2007 low-emissions engine lubricant specifications; this offering is designed for the fleet class of trade that seeks economically efficient engine oil. Both Guardol ECT and Fleet Supreme EC engine oils are made from advanced low-sulfated ash, phosphorus and sulfur (SAPS) technology to protect the performance and life of exhaust aftertreatment devices in new engines, without compromising protection in older engines.

“The introduction of Guardol ECT and Fleet Supreme EC engine oils further demonstrates ConocoPhillips Lubricants’ commitment to being the best supplier in the lubricants business,” Dias says. “Our goal is to produce products that meet or exceed the industry specifications across our Conoco, Phillips 66 and 76 Lubricants brands. The approach we are taking will also assist customers in simplifying their inventory management while providing enhanced marketing support.”

ConocoPhillips Lubricants will continue to offer its heritage lines of diesel engine oils that meet the API CI-4 Plus specification to satisfy customer needs in the off-highway industry, including 76 Royal Triton QLT, 76 Guardol QLT, 76 T5X Heavy Duty, Conoco Hydroclear Power-D, Conoco HD Fleet Supreme and Phillips Super HD II.
