Having low tire pressure causes more drag between your tires and the road, thereby
making your engine work even harder. Improper tire pressure can reduce the lifespan
of your tires and gas mileage by up to 30% or more, Check your tire pressure when
your tires are cold for accurate readings. DMC recommends that you do a tire pressure
check every time you fill your fuel tank. Another option is to have your tires filled with
Nitrogen which is more stable gas. Some of the benefits of Nitrogen in tires are less
fluctuation in the tire pressure, reduces tire pressure leak down under increased
temperatures and longer lasting tire life.
Engine Performance:
If your vehicle's spark plugs or spark plug wires are misfiring, you could be loosing up
to 30% in fuel efficiency. Another consideration is your engine's fuel delivery system
including the fuel filter, fuel injectors and the air induced system. Regular inspection
and servicing of the fuel system as well as spark plugs and wire will help prevent loss
of fuel efficiency. Ask your Service Manager about our TuneUp.
Air Filters:
When your engines air filter becomes clogged it starves the engine for air. The onboard
computers adjust for this by increasing the amount of fuel to maintain consistent firing
in the cylinders. This can cause up to 10% in decreased fuel efficiency. At DMC we
inspect your air filter every time you visit as part of our famous 27 point inspection.
Obey the Speed Limit:
Make sure you are driving the speed limit. Not only is that the law but is also increases fuel efficiency. According to the U.S. Department of Energy, you will pay an additional 5 mph above 60 mph.
Check your Gas Cap:
Broken, loose or missing gas caps causes your gas to evaporate and allowing it to escape out of your tank into the atmosphere. The simple of evaporation can work against you making your vehicle lose gas. Make sure you tighten your gas cap or replace as needed.
Weight Limit:
Do not pack your truck with anything that is not absolutely necessary. The more weight that you add to your car, the more fuel it will take to pull it down the road.
Engine Oil:
Change the oil when due and always use the correct oil for your vehicle. Dirty oil or incorrect grades can increase engine friction, thereby reducing fuel efficiency. Ask your Service Manager for more information about our oil change.
Preventative Maintenance:
Follow your vehicle manufacturer recommended maintenance schedule. If you keep your vehicle properly maintained, it will run at peak efficiency levels. Ask your Service Manager for a copy of your specific vehicle recommended maintenance.
