How does Rotella T6 5w40 How does Rotella T6 5w40 save money? $ Improved Energy Savings $ Extended oil drain intervals $ Extended engine life $ Reduced labor cost $ Reduced oil consumption $ Improved cold weather operation 8

Slide 10

$ Improved Energy Savings through lower viscous friction in lubricated contacts and by reducing the energy used to pump the oil through the engine through lower viscous friction in lubricated contacts and by reducing the energy used to pump the oil through the engine This can reduce fuel costs up to 1.5% or more as demonstrated in 2009 on-the-road field testing in medium duty trucks. For a typical truck* covering 100,000 miles annually, thats a savings of approximately 250 gallons of diesel fuel. At $3.75 a gallon, thats an annual savings of $937.50 per truck per year. This can reduce fuel costs up to 1.5% or more as demonstrated in 2009 on-the-road field testing in medium duty trucks. For a typical truck* covering 100,000 miles annually, thats a savings of approximately 250 gallons of diesel fuel. At $3.75 a gallon, thats an annual savings of $937.50 per truck per year. * assumes fuel consumption of 6 miles per gallon 9
