Petro-Canada 10W-40 synthetic first to pass Mack’s EO-N spec

Truck News

Toronto, ON — Petro-Canada’s DURON XL Synthetic Blend 10W-40 is the first 10W-40 grade heavy duty engine oil (HDEO) to achieve Mack Trucks Inc.’s EO-N Premium Plus ’03 specification.

The bled is formulated for operators requiring a HDEO with low-temperature capabilities that can meet the latest low-emission engine requirements.

"DURON XL Synthetic Blend 10W-40 provides increased wear protection and soot-fighting capabilities to protect engines longer, whether they are the latest low-emission engines or higher mileage engines," said Jim Putz, Category Manager, Commercial Transportation Products, Petro-Canada.

The Mack EO-N Premium Plus ’03 specification is required for the Mack ASET family of engines, which utilize exhaust gas recirculation (EGR), and is also highly recommended for all other Mack engine models, regardless of
vintage. To achieve this specification, a HDEO needs to perform at an acceptable level in the new Mack T-11 test with six per cent soot load, demonstrate used oil pumpability at high soot load and pass a severe shear
stability test.

DURON XL Synthetic Blend 10W-40 is formulated from the patented HT purity process Petro-Canada uses to produce 99.9 per cent pure, crystal-clear base oils. By removing the impurities that hinder competitive engine oil
performance, DURON XL Synthetic Blend retains its "fresh oil" properties longer. Petro-Canada blends in specialty additives for even longer fluid life and greater equipment protection from abrasive soot particles.

Petro-Canada offers a line of DURON heavy duty engine oils including synthetic, synthetic blend, single grade and multigrade heavy duty engine oils. DURON heavy duty engine oils are covered by Petro-Canada’s omprehensive "No-Nonsense Lubricants Warranty."
