Cenex's Superlube TMS 15W-40More than 134 million miles down the road, Cenex's Superlube TMS 15W-40 diesel oil has proven a clean, healthy lubricant for heavy-duty engines. Following multi-year, over-the-road tests in which 70 trucks traveled the equivalent of about 5,380 trips around the Earth, "engine parts were evaluated and found in excellent condition with superior sludge cleanliness," reports Bob Theisen, lubricants technical services manager with CHS, parent company of the Cenex brand. Particularly impressive for a test of this magnitude, the cylinder liners showed very minimal wear, says Theisen.
