Champion Oil has introduced a synthetic heavy-duty diesel engine oil it says offers the same wear and corrosion protections as its leading competitors, but with the added attraction of better fuel economy. The new Blue Flame SAE 5W-30 meets or exceeds specifications including API CJ-4/SN; Daimler MB 228.51 and 228.31; Volvo VDS-4, VDS-3 and CNG; Mack EO-N, EO-M Plus; Cummins CES 20081 and many others. With this lower viscosity, Champion said, independent testing showed the new engine oil delivered an average of 3.3 percent and up to 4.5 percent fuel economy improvement versus its SAE 15W-40 rivals, through reduced internal drag inside engines.
