The need for even more efficient internal combustion engines in the road transportation sector is a mandatory step to reduce the related CO2 emissions. In particular, this sector is presently responsible of about 12% of the greenhouse gases worldwide, and the path toward hybrid and electric powertrains has just begun. In particular, in heavy-duty vehicles the full electrification of the powertrain is far to be imagined. So, internal combustion engines will still play a significant role in the near/medium future. Hence, technologies having a low costs to benefits ratio will be favorably introduced in existing engines to reduce emissions. The thermal management of engines is today a recognized area of research. Inside this area, the interest toward the lubricant oil has a great potential but not yet fully exploited. Engine oil is responsible of the mechanical efficiency of the engine and has a significant potential of improvement.
