MISSISSAUGA, Ont. — Petro-Canada has unveiled DURON*-E, the company’s next-generation, heavy duty engine oil (HDEO) brand for the API CJ-4 category (formerly known as PC-10).

DURON-E will complement the current DURON line of premium heavy duty engine oil and will therefore offer choice and flexibility to both on-road and off-road customers. DURON-E features enhanced soot fighting capabilities in addition to improved wear protection, oil consumption, and piston deposits versus the previous CI-4 Plus category, according to Petro-Canada.

DURON-E, available in three performance offerings DURON-E 15W-40, DURON-E XL Synthetic Blend 15W-40 and DURON-E Synthetic 10W-40 – has undergone engine testing and has demonstrated extended drain capabilities in severe service field trials in both EGR and conventional diesel engines, Petro-Canada reports. DURON-E is formulated to meet the latest OEM specifications for their ’07 low emission engines equipped with an advanced exhaust aftertreatment device. DURON-E is back-serviceable and carries the API CI-4 Plus, CI-4, CH-4, CG-4 licenses required by pre-’07 diesel engines.

“There are a number of reasons why Petro-Canada’s DURON-E brand exceeds the requirements for CJ-4,” stated Jim Putz, Category Manager, Commercial Transportation Lubricants, Petro-Canada Lubricants. “Now more than ever, purity is an issue and particulates and contaminants are an even bigger risk factor for next generation engines equipped with diesel particulate filters. Petro-Canada understands these issues. Our base oils are one of the purest in the world – 99.9% pure – and this is where we start the process with any new product developed. Next, our oils have always been low in sulphur and sulphated ash versus competitive HDEOs. In fact, we’ve been producing and blending with low sulphur base oils for over 25 years. DURON-E is the direct result of our leading edge technology and expertise coming together to produce innovative products that could save customers money.”
