Engine Oil Tips for Fleets

Engine Oil Tips for Fleets - Engine oils for heavy equipment have evolved over the years in keeping up with Tier 4 diesel engine technology. The best oil will help your fleet machinery and equipment work in tip-top condition. With winter coming, this is even more imperative. Demands on heavy-duty diesel engine oils have been changing with revolutions in engine technology and fuel formulations. About 25 years ago, fuel sulfur levels were at 5,000 ppm, as this substance went through the piston rings and into the crankcase to form sulfuric acid. Additives in the oil were applied in an effort to neutralize that acid. However, with depletion of additives, oil changes had to be made. On top of that, sulfur levels dropped and soot control issues cropped up, leading to a change in the way manufacturers set up and calibrated diesel engines. As a result, fuel soot formed in the crankcase, leading to the need for draining. With the introduction of modern emissions equipment, the crankcase environment improved. But now oil oxidation is a concern. Viscosity Engine oil must form a protective film, which guards against metal-on-metal contact. There are many measures of viscosity, but the two most common are: KinematicAbsolute [...]
