Petro-Canada today announced the launch of an API CJ-4 certified heavy-duty engine oil—Duron-E. It features enhanced soot fighting capabilities in addition to improved wear protection, oil consumption, and piston deposits versus oil meeting the previous CI-4 Plus service category, Petro-Canada said.

Duron-E exceeds API CJ-4 specification for ‘07 U.S. Environmental Protection Agency-compliant engines, the oil maker said.

Duron-E is available in three offerings: Duron-E 15W-40, Duron-E XL synthetic 15W-40 and Duron-E Synthetic 10W-40. These products demonstrated extended drain capabilities in severe-service field trials in both EGR and conventional diesel engines, the company said. Duron-E could be used in pre-’07 models since it carries API CI-4 Plus, CI-4, CH-4, CG-4 licenses.
