Known for its highly aerodynamic models with fuel efficient powertrains - such as the Kenworth T680 with the PACCAR MX-13 engine - Kenworth last week announced it has selected the fuel economy-focused Chevron's Delo(R) 400 XLE Synblend SAE 10W-30* as standard factory fill for new Kenworth Class 8 diesel trucks.

Delo 400XLE Synblend SAE 10W-30, formulated with ISOSYN(R) Technology, Chevron's exclusive combination of base oil and additive technology, provides excellent wear and soot control protection and minimizes deposit formation for on-highway trucks using ultra low sulfur diesel (ULSD). The oil has shown an ability to deliver a fuel economy improvement in Class 8 trucks over 15W-40 oils while maintaining lubricity, potentially resulting in a substantial savings for fleets and owner-operators.

"Kenworth continually explores ways to offer products that help enhance our customers' bottom line. We've been partners with Chevron for more than 20 years and their latest, fuel-efficient Delo 400 XLE Synblend 10W-30 oil provides a good opportunity for additional fuel efficiency gains," said Kurt Swihart, Kenworth marketing director.

Kenworth's Class 8 truck assembly plants in Chillicothe, Ohio and Renton, Washington will offer the oil as standard.

The Kenworth T680 with the PACCAR MX-13 engine was recently awarded 2013 ATD Heavy Duty Commercial Truck of the Year honors.

Kenworth is a PACCAR company.
