Fuel Saving Tips
If you have a traditional automatic transmission with a torque converter, all modern ones can "lock-up". This happens when the torque converter stops slipping and there is a direct linkage from the engine to the drive wheels. This increases fuel economy because the torque converter is no longer creating heat that would otherwise be put to good use on the road. When it comes to hills, don't decelerate too much, be accustomed to your transmission and keep the necessary speed to keep the transmission locked-up when going up hills.
