Synthetic lubricant boosts gearbox efficiency

ExxonMobil worked with its distribution partner Den Hartog to undertake the tests which were carried out using power and torque monitoring devices and a selection of representative oils.
The results indicated that Mobil SHC 626 gear oil helped to improve gearbox thermal and mechanical efficiency by 0.27% compared with Mobil DelvacTM 1330 engine oil. For a fully mechanically optimised gearbox, this equates to a significant reduction in total energy losses of 10% and an approximate saving of EUR 1,400 a year. Further potential savings could arise from extended component and oil life, plus longer maintenance intervals, the companies said.
