Lubrication Facts & Knowledge

Electric vehicle lubrication

Electric vehicles may have no engine oil, but they still need specialized lubricants for their single-speed gearboxes and electric motors. These EV fluids must handle constant high RPMs, which are typical for electric motors, unlike the varying speeds of gasoline engines. Traditional oils can conduct electricity, which would be dangerous around electric components, so EV lubricants are formulated to be electrically insulating. Some electric cars can go 150,000 miles before needing a gearbox fluid change, far longer than conventional transmission fluid.
