HOW CAN WE HELP YOU?

Diesel engine designs continue to evolve to meet ever-changing emissions and fuel economy requirements. The technologies in newer engines, such as high exhaust gas recirculation (EGR), complex exhaust aftertreatment systems, improved combustion systems and higher peak cylinder pressures, place increased demands on crankcase lubricants. Lubricants and lubricant test procedures also continue to evolve to meet these demands.

We are one of the oldest and largest service providers for the evaluation of engine lubricants used in diesel engines for factory fill and service fill requirements. Facilities and staff are available to evaluate lubricants against the American Petroleum Institute (API) CH-4, CI-4, CI-4 PLUS, CJ-4, CK-4 and FA-4 as well as Cummins, Mack, and John Deere requirements. Evaluations are performed with respect to engine oil soot handling, oil oxidation, wear (camshaft lobes, camshaft followers, piston rings, piston liners, and connecting rod bearings), oil consumption, piston deposits, and fuel economy. New design engine components are also evaluated to determine acceptability with current day lubricants. In addition to engine based testing, we perform all related analytical bench tests required to qualify lubricants.

SwRI has over 43 test stands available for diesel lubricant test procedures, which utilize engines representative of heavy-duty diesel engines operating in modern commercial fleets and off-highway applications, including:
