Improving Fuel Effi ciency
Driving Tips
Keep Vehicle Speed Down:
Fuel effi ciency drops by 0.10 mpg for every 1 mph over
55 mph.
Cruise in Top Gear:
For maximum fuel effi ciency, utilize the following shift
parameters:
1. Operate highest gear possible/do not run
one gear down
2. Keep the engine below 1500 rpm
3. Downshift around 1100 rpm
4. Use progressive shifting techniques
-Upshift at 1400-1500 rpm in upper gears
-Upshift at 1100-1300 rpm in lower gears
Use Cruise Control Whenever Possible:
Using cruise control helps maintain average speed and
good fuel effi ciency.
Avoid Downshifting too Early When Climbing Grades
Caterpillar engines allow you to “lug the engine”
(i.e. operate at 1000-1200 rpm), as long as the engine
maintains road speed while climbing a grade in the
1000-1200 rpm range. In this situation, there is no need
to downshift.
Do Not Run with “Fan On” Unless Required
The fan draws horsepower and reduces fuel effi ciency.
Under normal operating conditions, leave the fan switch
in the automatic mode while driving, which allows the
fan to activate only when needed.
Stay Alert to Changing Road Conditions
Anticipate possible slowdowns and stops, and coast in
gear to improve overall fuel effi ciency.
Eliminate Idle Time
Caterpillar engines with ACERT Technology do not
require long cool-down periods. Therefore, do not idle
for long periods of time.
-If the vehicle is to parked for more than 5 minutes,
shut it down
-If idling for heating or cooling, idle between
800-1000 rpm
Please note that a reduction in idle time from 50% to 25%
can improve mpg by 2% to 4%
