Duron meets CI-4

TORONTO, Ont. — Petro-Canada’s Duron heavy-duty engine oil has achieved the American Petroleum Institute’s (API) new CI-4 performance standard.

This means the oil is certified to meet the more stringent low emission demands set to be rolled out across North America in October 2002 in all new heavy-duty diesel engines.

Duron is formulated from the patented HT Purity process, which Petro-Canada uses to produce base oils that it says are 99.9 per cent pure. These high-quality base oils have virtually all aromatics, sulphur and nitrogen impurities removed.

As a result, the company says it has outstanding soot dispersion capability and maintains its oxidative stability at higher operating temperatures, including those generated in post-October 2002 engines featuring new exhaust gas recirculation (EGR) systems.

“Petro-Canada has always been ahead of the curve in meeting the most stringent emission and performance standards in the industry,” says Jim Abram, category manager, Heavy Duty Engine Oils and Commercial Products, Petro-Canada.

“The API CI-4 standard was a natural progression for Duron because it was originally formulated as a superior soot fighter.”

The API CI-4 standard officially comes into effect in September 2002, replacing the old API CH-4 specification introduced in 1998.
