The Dodge Ram 2500 is Dodge's mid-size pickup truck. Larger than the Ram 1500, but lighter than the 3500 series, the 2500 is used both as a work truck and as a family vehicle. As with most pickups, fuel efficiency is somewhat sacrificed in favour of torque and hauling capacity. Driving the diesel version of the 2500 will save quite a bit of fuel as compared to the gasoline model, but you can also eke out some mileage gains by a little bit of proactive maintenance and some changes to your driving habits.
1 Keep close to the speed limit on the highway. Peak fuel efficiency for most vehicles is at around 60mph, and falls off quite dramatically at speeds just above that.
2 Keep your truck as light as you can. Pickups are meant to carry cargo, and often end up carrying extra gear that isn't actually needed. Every 45.4 Kilogram of that weight can drop your mileage by up to 2 per cent, so it pays to stop and pull out whatever you don't need on a given trip.
3 Drive smoothly. Sudden acceleration and braking and sharp turning have a huge effect on mileage, especially when driving at speed on the highway, where they can reduce your mileage by 33 per cent. In town, this type of driving still reduces mileage by up to 5 per cent, so driving carefully makes a great deal of sense.
4 Put your truck in its overdrive gear once you're at a steady speed. This will let the engine rest, spinning at a lower rate relative to the wheels and burning less fuel.
5 Switch on your cruise control. By keeping your 2500 moving at a steady speed, cruise control will reduce the mileage impact of unnecessary acceleration and braking.
1 Maintain your engine. Although diesels generally require less maintenance than gasoline engines, an engine tune-up should still be able to gain you some mileage by cleaning your fuel and air filters, replacing worn glow plugs, and adjusting the engine's timing to its most efficient setting. Taken together, you can get a 4 per cent mileage boost from these things. If there is a bigger problem, such as a faulty oxygen sensor causing your engine to run rich or ragged, repairing it can give you up to a 40 per cent mileage improvement.
2 Put air in your tires. Under-inflated tires will produce inefficient levels of friction with the ground and use up more fuel. To find the optimal tire pressure, look in your manual or on the sticker mounted inside your driver's side door jamb. Use this, not the maximum figure printed on the tire itself, and you could increase your mileage by up to 3.3 per cent.
3 Use the grade of oil recommended by Dodge in your Ram 2500's manual. This can give you a 1-2 per cent mileage boost, especially if you buy oil that is marked "Energy Conserving," which indicates that it contains additives that reduce engine friction still further.
