Delo® 400 LE SAE 10W-30 Demonstrates Fuel Economy Improvements Over 15W-40 Oils

Chevron’s Delo brand of technologically advanced engine oils, lubricants and coolants, today announced that after extensive laboratory and field testing in heavy-duty engines, its Delo® 400 LE SAE 10W-30 oil has demonstrated an ability to provide fuel economy improvements over the more commonly used 15W-40 grade diesel oil. Delo 400 LE 10W-30 showed a 1% fuel economy improvement over 15W-40 oils and a 0.5% fuel economy improvement over 5W-40 grade synthetic lubricants. For fleets, the savings associated with these fuel economy improvements can be substantial.

The use of the lower viscosity Delo 400 LE 10W-30 does not come at the expense of engine durability. In fact, Chevron also conducted extensive laboratory and field durability tests with Delo 400 LE 10W-30 that proved the product provides wear levels and oil drains that fleets have come to expect from the leading 15W-40 motor oils. Durability tests were conducted on a number of diesel platforms, including Detroit Diesel DD15, Cummins ISX, Mack MP7 and DAF 12.9 Liter.

Chevron also tested its Delo 400 LE 10W-30 on 2010 engines from Volvo and experienced similar durability and fuel economy results.

This incredible combination of fuel economy and engine durability is a result of Chevron’s proprietary ISOSYN™ Technology which combines highly refined base oils with advanced additives to create products that rival synthetic lubricants in critical performance tests while maintaining costs similar to mineral-based oils.

"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.”
