Toronto, (Sept. 2, 2004) — Petro-Canada’s DURON 15W-40 and DURON XL Synthetic Blend 15W-40 heavy duty engine oils have achieved the American Petroleum Institute’s (API) CI-4 Plus specification.
The new specification requires heavy-duty engine oils to provide improved shear stability and soot-handling abilities for low-emission engines and comes into effect September 1, 2004.
“With the increased soot loads generated by the new low-emission engines, it is essential to use a heavy duty engine oil with the highest soot-dispersion capabilities available,” said Jim Putz, category manager of Petro C an’s Commercial Transportation Products.
DURON 15W-40 and DURON XL Synthetic Blend 15W-40 are 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 retains its “fresh oil” properties longer, the company claims.
The API CI-4 Plus specification is a supplement to the API CI-4 specification introduced in 2002. API CI-4 Plus was developed specifically to address the demands of lower emission 2004 diesel engines equipped with EGR systems.
