Energy Losses in a Passenger Car

  • Only 17%–21% of the energy from the fuel you put in your tank gets used to move your car down the road.
  • Rest of the energy is lost to engine and driveline inefficiencies or used to power accessories.
  • Potential to improve fuel efficiency with advanced technologies is enormous.

The best passenger car engine lubricants are currently about 4-5% more efficient than their early 1990s counterparts as a result of lubricant development.
