Fuel Filter Maintenance For Ram Ecodiesel: How Often To Change?

The frequency with which you should change the fuel filter on a Ram EcoDiesel varies according to different sources. The owner's manual for the 2021 Ram 1500 EcoDiesel recommends changing the fuel filter every 30,000 miles or 36 months when using conventional no. 2 diesel or up to B5 biodiesel blends, and every 20,000 miles or 24 months when using a biodiesel blend greater than B5. However, some owners opt to change their fuel filters more frequently, such as every 15,000 miles or 20,000 miles, or even at every oil change, to ensure optimal performance and prevent engine issues. The cost of changing the fuel filter can vary depending on whether it is done at a dealership or independently, with some dealership charges being considered excessive by owners.

Fuel filter replacement intervals vary by state

The frequency with which you should change the fuel filter on a Ram EcoDiesel varies according to the state in which you live. This is due to differences in fuel quality across the United States.

The 2021 Ram 1500 EcoDiesel owner's manual states that under normal conditions, the diesel fuel filter should be replaced every 20,000 miles (every other oil change). However, if the vehicle is being used in certain geographical areas, namely Pennsylvania, New York, Ohio, Maryland, West Virginia, Arkansas, Oklahoma, Kansas, Iowa, Missouri and Nebraska, it is recommended to replace the fuel filter every 10,000 miles. This is due to "fuel cleanliness issues" in these states.

Some Ram EcoDiesel owners opt to change their fuel filter more frequently than the manufacturer's recommendation, with some choosing to do so every 15,000 miles or even every 10,000 miles, especially if they are using a biodiesel blend. Others choose to change the filter seasonally, at the beginning of fall and spring, to ensure that there is no moisture in the system during winter.

The cost of changing the fuel filter can vary significantly, with some dealership prices ranging from $125 to $222, while others quote much higher prices of around $750 for an oil change and fuel filter replacement. It is a relatively simple task to perform yourself, with many people opting to buy the necessary parts and either do the job themselves or take them to a local garage to be fitted, thus saving on labour costs.

Fuel filter replacement intervals vary by fuel type

The frequency of fuel filter replacement also depends on the quality and source of the fuel. For instance, if you are refuelling in certain geographical areas, the fuel may be dirtier, and it is recommended to replace the fuel filter more frequently. In the United States, some states with known fuel cleanliness issues include Pennsylvania, New York, Ohio, Maryland, West Virginia, Arkansas, Oklahoma, Kansas, Iowa, Missouri, and Nebraska.

Additionally, the maintenance schedule for fuel filters can be affected by frequent towing or hauling and off-road use. It is recommended to replace the fuel filter every 15,000 miles under severe operating conditions.

Some vehicle owners choose to change their fuel filters more frequently as a preventative measure. For example, some individuals change their filters twice a year, at the beginning of fall and spring, to ensure that there is no moisture in the system before winter and to remove any contaminants that may have built up during the warmer months.

It is important to refer to the vehicle's owner's manual and follow the recommended maintenance schedule for fuel filter replacement to ensure optimal performance and avoid any potential issues.

Fuel filter replacement cost

The fuel filter in your car helps to remove contaminants and impurities, such as rust and dirt, from the fuel before it reaches the engine. It is an essential component for optimal engine performance.

The cost of replacing a fuel filter depends on the type of car you have and the type of filter you need. The average cost for a replacement is between $70 and $150, but this can vary depending on labour costs and the specific make and model of your car. For example, a fuel filter replacement for a Ram EcoDiesel truck can cost up to $222 at a dealership.

If you are handy with car maintenance, you can buy a new filter for around $50 and install it yourself. However, if you take your car to a mechanic or dealership, you can expect to pay between $90 and $142 or between $50 and $215 for the part and labour.

It is recommended to replace your fuel filter periodically as part of your vehicle's repair and maintenance schedule. Many car companies suggest changing the fuel filter every 5 years/50,000 miles, but this may vary depending on your driving habits, the age of your vehicle, and the manufacturer's recommendations.

Some signs that it may be time to replace your fuel filter include difficulty starting the engine, excessive vibration while idling, and sluggish performance, especially at slow speeds.

Fuel filter replacement: dealership vs. independent shop

When it comes to replacing your fuel filter on your Ram EcoDiesel, you have two main options: taking it to a dealership or an independent shop. Here are some things to consider when deciding which route to take:

Dealership

Dealerships will have factory-trained technicians who are familiar with the specific requirements of your Ram EcoDiesel. They will have the proper tools and equipment to perform the fuel filter replacement and may offer a warranty on their work. However, dealerships often charge higher labour rates, and you may have to wait longer for an appointment. Some dealerships may also try to upsell you on additional services or repairs that may not be necessary. It is recommended to get quotes from multiple dealerships and compare prices before making a decision.

Independent Shop

Independent shops typically have lower labour rates than dealerships, and you may be able to find a shop that specialises in diesel engines or Ram vehicles. They may also be more flexible with scheduling and have shorter wait times. However, it is important to ensure that the independent shop has experienced technicians who are familiar with your specific vehicle and its fuel system. It is always a good idea to check reviews and ask for recommendations from other Ram EcoDiesel owners before choosing an independent shop.

Fuel Filter Replacement Interval

The recommended fuel filter replacement interval for the Ram EcoDiesel varies depending on the source of information. Some owners manuals and dealerships suggest replacing the fuel filter every 20,000 miles or every other oil change. Others recommend replacement at every oil change, not exceeding 10,000 miles. It is important to refer to your specific owner's manual and follow the recommended maintenance schedule to avoid voiding your warranty. Additionally, some states with known fuel cleanliness issues, such as Pennsylvania, New York, and Ohio, recommend more frequent fuel filter replacements.

DIY Option

Replacing the fuel filter on a Ram EcoDiesel is a relatively straightforward task that can be completed by mechanically inclined individuals. Online forums and communities dedicated to Ram EcoDiesel vehicles provide detailed instructions and tips for DIY fuel filter replacements. However, this option may not be suitable for everyone, especially those without mechanical experience or the necessary tools.
