How to Improve the Fuel Economy of a Dodge Ram Cummins Diesel Truck

A commonly asked question is how one can improve the fuel economy in their Dodge Diesel. Economically, the world has seen a tightening in the pocket book. It seems that everything is getting more and more expensive and customers feel that economic pressure, especially at the fuel station. Diesel fuel prices have increased over the past few years and customers are looking for ways to reduce the “pain at the pump.” Here are a few suggestions to help get the most fuel economy out of your Dodge Ram Cummins Diesel.

The first and cheapest improvement you can make is to increase your tire pressure to the maximum allowable tire pressure. This added pressure will reduce the rolling resistance and help you improve fuel economy. When tires have low pressure, they require more energy to turn over when compared to a high pressure tire.

Second, make sure the truck has good working components. Make sure your front end is properly aligned. Having misaligned tires simply wastes energy as they pull the truck in different directions. Also, inspect the brake calipers. In older trucks especially, calipers can become sticky and drag on the brakes unnecessarily.

Another suggestion that we highly recommend, is the addition of a smarty tuner to your Dodge Ram Cummins Diesel. In the world of diesel performance, there is an incredible amount of options available. Smarty is the only tuner that is vehicle specific. While other makes and models utilize a V8 diesel, the Cummins platform in a Dodge is an inline 6 cylinder. These different engines have different characteristics that make a “generic” tune less desirable. A Smarty tuner, written only for the 5.9L and 6.7L Cummins, gives it a distinct advantage.

Adding a smarty tuner will give you the ability to increase the timing on your truck and yet still remain within safe parameters. Increasing the timing means that the diesel fuel is injected into the cylinder sooner and therefore allows the diesel fuel more time to burn completely. With a complete fuel burn, there is more power output than there would be otherwise and this can increase the fuel economy.

The Smarty Tuner can also perform a multitude of other functions. It will read diagnostic trouble codes, allow you to make tire height adjustments and in the case of the smarty touch, monitor engine parameters while the engine is running.

In most cases, the fuel economy in your Dodge Ram Cummins Diesel can be improved. If you are experiencing extremely poor fuel economy, you may have injector problems or another engine problem.
