As a consequence of the increasingly stringent emissions standards in the world and, on the other hand, the foreseen shortage of fossil fuels, the application of low viscosity engine lubricants (LVO) is considered one of the most cost effective contribution to counteract these challenges. The aim of the test was to verify the potential fuel consumption benefits of using LVO in Heavy Duty Vehicles (HDV) found in literature, mainly obtained in engine bench tests, when they are working on real and “on-road” conditions. Parallel to this study, the performance of low viscosity lubricants regarding to engine wear was assessed, since the use of LVO could imply an increase in engine wear rate. Potential higher wear could result in a life cycle reduction for the internal combustion engines or higher maintenance costs, both nondesired effects. In order to achieve this goal, a sample of 39 urban buses comprising two engine technologies (Diesel and Compressed Natural Gas (CNG)) and ...
