*A fuel economy evaluation was conducted using two Volvo FH500 6x2 Euro 6 trucks, loaded to 60 percent payload (circa 32,000kg). Testing was conducted on track at the Millbrook Proving Ground, Ltd. in the United Kingdom. Statistically significant fuel economy benefits were observed in the Volvo trucks when comparing Mobil Delvac 1™ ESP 5W-30 to a mineral 15W-40 engine oil with an average fuel economy gain of 2.6 percent for city driving conditions. Corrections were applied when changes in test environment had a statistically significant impact on fuel economy. Fuel economy improvements are dependent on vehicle/equipment type, outside temperature, driving conditions and your current fluid viscosities.
