Measuring lubricant related fuel economy of internal combustion [IC] engines presents technical challenges, due to the relatively small differences attributable to lubricants. As engine technology progresses, large benefits become harder to find; so the importance of precise measurement increases. Responding to the challenge of meeting CO2 targets, many successful IC engine technologies have been deployed; these include downsizing/rightsizing[1], mechanical efficiency improvements, advanced charging and combustion systems, thermal management, sophisticated electronic control and calibration. These technologies have been deployed against a back-drop of increasingly stringent emission requirements. Increasing attention is focused on technologies which offer smaller but important contributions. The search for smaller improvements combined with growing engine and vehicle technology complexity increases the challenge of producing high quality data.
