RAM Ram 2500 2010-2018 Fuel System Specifications

The 2010-2018 Ram 2500 is compatible with diesel fuel, specifically Ultra-Low Sulfur Diesel (ULSD) with a sulfur content of 15 parts per million (ppm) or less. Using the correct fuel ensures optimal engine performance and compliance with emission standards. Avoid using gasoline or biodiesel blends above 5% (B5) as they can damage the engine and void the warranty.

Regular maintenance for the Ram 2500 fuel system includes replacing the fuel filter every 15,000 to 30,000 miles, inspecting fuel lines for leaks or damage, and using fuel additives to prevent injector clogging. Additionally, ensure the fuel tank is cleaned periodically to remove sediment and contaminants. Following the vehicle’s maintenance schedule in the owner’s manual is crucial for longevity.

To replace the fuel filter, first, locate it near the fuel tank or engine bay. Relieve fuel system pressure by disconnecting the fuel pump relay and running the engine until it stalls. Disconnect the fuel lines and electrical connectors, then remove the old filter. Install the new filter, reconnect the lines and connectors, and prime the system by cycling the ignition key several times before starting the engine.

Poor fuel economy in the Ram 2500 can result from clogged fuel injectors, a dirty air filter, or incorrect tire pressure. Start by checking and replacing the air filter, ensuring tires are inflated to the recommended PSI, and using a fuel injector cleaner. If issues persist, inspect the fuel system for leaks or consult a professional for diagnostics.

To optimize fuel performance, use high-quality ULSD, maintain proper tire pressure, and avoid excessive idling. Regularly replace the fuel and air filters, and consider using fuel additives to keep the injectors clean. Driving at moderate speeds and avoiding heavy loads when possible also improves fuel efficiency. Follow the manufacturer’s maintenance schedule for best results.
