Top 5 ways drivers can instantly improve fuel economy
Driver skill, or lack thereof, along with habits and behavior can have a huge impact on fuel efficiency. It is said there can be a difference of something like 30% between a fleet’s best and worst driver. Sure, technology can level that playing field to some extent, but some things computers can’t fix. Here are five tips guaranteed to save fuel, no matter how your trucks are spec’d:
1. Avoid unnecessary braking — Maintaining a few miles per hour slower than the prevailing traffic flow will reduce the need to decelerate for slower traffic and then speed up again. Getting off the throttle pedal sooner and coasting to a stop light rather than braking, when possible, means less fuel burned. Use gravity-generated momentum when safe to do so by rolling down a hill and part way up the other side, rather than braking on the hill to maintain a prescribed speed.
2. Don’t idle, ever— Vehicles equipped with auxiliary climate control systems do not ever need to idle except a few moments before shutdown after a hard pull. Remind drivers that all the myths they have ever heard that idling is necessary to warm up an engine, or that less fuel is burned during five minutes of idling than when starting an engine are just that, myths. Shut off the engine whenever possible, even for a few minutes.
3. Accelerate gently— Drive the truck like you have an egg between your foot and the throttle pedal. Even though AMTs will shift according to their programming, most take cues from how aggressively the driver hits the pedal. High throttle demand usually produces higher revs between gears and more aggressive shifts.
4. Reduce the gap— When proper axle loading permits, keep the trailer cinched up as close to the tractor as possible. The tractor-trailer gap is a big fuel waster, and it should be minimized whenever the opportunity arises.
5. Drive the truck— Drivers have one big advantage over most of the automated functions on a truck; they can see the road. Rather than leaving the cruise control on all the time, manage speed and momentum in hills by backing off the throttle when nearing the crest of a hill, for example. There’s no need to go over the top at full power. Back off the throttle sooner when coming to a stop, and manage road speed according to traffic conditions rather than letting the cruise bring you in so close to another car that you have to brake.
