SAN RAMON, Cal. — Moving from the commonly-used 15W-40 heavy-duty engine oil to Chevron Delo 400 LE SAE 10W-30 could provide a 1% fuel savings, according to extensive test results conducted by Chevron.


The company says it has completed extensive lab and field testing in heavy-duty engines and has found its 10W-30 grade oil also boasts a 0.5% fuel savings over 5W-40 grade synthetic oils.


Chevron said testing also showed wear levels and drain intervals provided by its 10W-30 equal what fleets would expect from leading 15W-40 motor oils. The tests included 2010 engines from Volvo with similar results.


Chevron is crediting its proprietary ISOSYN technology for the improvements. The technology combines highly-refined base oils with advanced additives to create products that rival synthetic lubes in performance tests while maintaining the costs of mineral-based oils, according to the company.


“ISOSYN Technology is what differentiates Delo from the competition,” said Len Badal, commercial enterprise manager, Chevron Global Lubricants. “This unique Chevron Delo technology makes synthetics and synthetic-blends unnecessary from a cost and performance standpoint in all but the most extreme environments. We have years of data to substantiate this claim. Regardless of the economic climate, most fleets can’t afford to throw away money. Delo 400 LE 10W-30 provides excellent performance at an optimal price point.”
