High gas prices are something we can’t ignore. Fortunately, the Moran service center can help cut your costs at the pump. Moran Certified Pre-Owned has three maintenance tasks to save you fuel and money.

Change the Oil

One of the main jobs of oil is to keep the moving parts in the engine adequately lubricated. This is easy when oil is clean and fresh. When it gets older, however, it gets contaminated with debris. When this happens, it hampers lubrication, which causes the engine to have to work harder to produce power. The result is a drop in gas mileage. An oil change at our Moran service center helps engine performance and fuel efficiency as a result.

Check the Pressure in Your Tires

It may seem odd, but your tires have a big impact on fuel economy. When they are underinflated, this increases rolling resistance, which is something else that makes the engine exert more power than it should. Have the air pressure checked to make sure that it is at the correct level per the manufacturer’s specifications.

Replace the Spark Plugs

Spark plugs play an important role in your vehicle, as they help ensure that fuel combusts completely and efficiently. When plugs get old, they can no longer do this as well. Check your vehicle’s owner’s manual because it could be time for a replacement.
