6 SIMPLE TRIED AND TRUE TIPS TO
BETTER MILEAGE WITH YOUR DIESEL TRUCK
#1 Increase Low-End Torque ='s BIGGEST GAINS!!!
THIS IS THE NUMBER ONE WAY TO INCREASE MILEAGE: On top of driving the right speed and keeping
your truck well maintained…. remapping your truck’s fuel table with DURAMILEAGE'S tried and true calibrations has produced the
biggest and most consistent fuel mileage gains of any aftermarket product.
The Duramileage MPG Series Modules work as well for Newer LML Duramax, Powerstroke, and Cummins.
#2 Proper Tire Size and Air Pressure:
Keep your tires properly inflated.
Under-inflated tires require more energy to roll, which not only wastes fuel,
but wears the tires out more quickly. According to the EPA, a tire that is
under-inflated by only two pounds per square inch can cause a 1 percent
increase in fuel consumption. Under-inflated tires can also build up excess
heat, which can lead to tire failure. Check your vehicle's tire pressure at
least once a month, when the tires are cold. Also, check the tires before and
after long trips. The recommended tire pressure is found on a label inside the
car, usually in a door jamb or inside the glove-box lid.
#3 Clean Injectors:
Electronic fuel
injection (EFI) systems are relatively trouble-free. However, that doesn’t make
them immune from potential problems. The most common issue involves fuel
deposits on injector tips. The reason? When an engine is turned off some fuel
remains in the injectors. Hot engines cause fuel to evaporate, which can leave
gum-like deposits that can change an injector’s ideal conical spray pattern to
an irregular one, or even reduce fuel volume to the combustion chambers and
cause drivability problems. Symptoms include excessive fuel usage as well as
stalling, hesitating, hard starting, and loss of power.
#4 Synthetic Oil:
Benefits: Synthetic oil lasts two to five times longer than conventional
oil; thus, waste oil generation can be reduced two to five times if synthetic
oil is used.
The lower friction resulting from the use of a
synthetic lubricant Synthetic oils have high resistance to changes in
viscosity due to temperature. As a result, they provide a heavier, more
stable protective oil film for engine bearings and piston rings than is
provided by similar SAE-grade mineral oils. Synthetic oil permits better cold weather performance
and longer endurance. Manufacturers claim that synthetic oil yields better
fuel economy, reductions in friction and wear, decreased oil consumption,
improved performance, and extended drain intervals. Disadvantages:
Synthetic oil costs more than conventional oil. However, the higher cost
is typically offset by reduced waste generation. Since synthetic oil has improved fluidity, oil loss
will occur more quickly through leaks because the thinner fluid will flow
through a bad seal or worn ring. Some synthetic compounds are not compatible with
conventional oils.
Recently a customer who used MOBIL 1 Synthetic in their Differentials reported an immediate 1.5 MPG increase and a MUCH SMOOTHER driving truck
#5 Drive 65:
Wind drag at 80 mph is 4 times as
great as at 40 mph. On the highway, in the 50-75 mph range, your fuel economy
will go down about 3 mpg for each 10 mph increase in speed.
Diesel trucks seem to get PEAK
efficiency around 2000 RPM which is normally around 65-70 MPH. Driving 65 with
the cruise control on will most likely give you the best mileage out of your
truck.
#6 Clean Air Filter and MAF Sensor:
A dirty air filter
blocks airflow to the turbo and makes it work harder, causing a decline in
horsepower and fuel economy. Although your truck’s owner’s manual may specify
an inspection interval for the air filter, it’s really best that it be checked
at every oil change. Dirty and dusty driving conditions will require more
frequent filter replacements, so keep this in mind. Driving with a dirty filter
can easily lower your fuel economy 10%.
If you use an
aftermarket washable filter…. make sure you clean the Mass Air Flow (MAF)
sensor located right behind your filter air box. This sensor gets junked up
especially from the oil from your aftermarket filter.
On top of driving the right speed and keeping
your truck well maintained…. remapping your truck’s fuel table with DURAMILEAGE'S tried and true calibrations has produced the
biggest and most consistent fuel mileage gains of any aftermarket product.
