Racing tech! "The smaller Internal Combustion Engine (ICE) and increased power per litre mean that the new engine runs hotter. Oil thins at higher temperatures and thus a hotter engine needs a thicker oil to stop metal components from rubbing together and failing.
However, the hotter conditions and reduced quantity of oil in the ICE (reduced from almost seven litres for the V8 to fewer than three litres for the V6) also mean that the oil must contribute more to cooling the engine. This requires thinner, faster flowing oil.
Additionally, the regulation changes restrict the quantity of fuel that can be consumed per race to 100 kg, which means that the oil needs to help conserve energy by minimising friction. Again, this requires thinner oil.
In order to meet these complex and contradicting requirements, the new engine oil for the 2014 car is a precisely balanced mixture of advanced, thinner synthetic base oils to help cooling and polymer viscosity boosters (which kick-in at higher temperatures) to thicken the oil. Friction-reducing oil components, which make it easier for metal surfaces to slide past each other, have also been used to improve overall fuel economy.
Another consideration is that the higher temperatures also make it more likely that the oil itself will stop working properly. High performance additives have been included to stop the oil from breaking down under these extreme conditions.
Energy losses in the gearbox can also have a significant impact on fuel economy. To address this, Petronas technologists have also produced precision gearbox lubricants for the 2014 car to ensure that energy losses in the transmission are kept to a minimum, whilst making sure that the gearbox is protected from failure.
