After laboratory and field testing in heavy-duty engines, Chevron's 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.
Use of the lower-viscosity Delo 400 LE 10W-30 does not come at the expense of engine durability. In fact, Chevron also conducted 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 combination of fuel economy and engine durability is a result of Chevron's proprietary ISOSYN technology. This technology combines highly refined base oils with additives to create products that rival synthetic lubricants in critical performance tests while maintaining costs similar to mineral-based oils. Delo 400 LE SAE 10W-30 is available in gallon jugs, five-gallon pails, 55-gallon drums, and in bulk.
