Dodge RAMs with HEMI engines do not get the best gas mileage. But there are some things you can do to increase your mileage. You may be able to increase gas mileage by three or four gallons which can add up to a lot of money in the long run. A simple change in driving habits and routine maintenance can make a big difference in your gas mileage.

Step 1

Change your RAM's oil every 3,000 miles or at least every three months. This keeps the engine clean and running well.

Step 2

Get a tune up. Regular tune ups involve changing the spark plugs and a general check of the engine. This ensures that everything is running smoothly. Skipping tune ups can cause your truck to run poorly and burn more gas than necessary.

Step 3

Avoid letting your Doge idle for long periods of time. You get zero mileage from idling. You actually burn more fuel idling in place than you would driving, so avoid it if possible.

Step 4

Check your tires often. Tires with low air pressure can cause pull during driving and use more gas. Temperature fluctuations can cause tires to lose air pressure. Add air if needed as soon as possible. Slightly flat tires can greatly bring down your gas mileage.

Step 5

Avoid accelerating quickly. This burns more gas than needed. Driving at high speeds can burn fuel a lot faster than if you drive the speed limit or just below it.

Step 6

Check your air filter. You should be able to hold it up to a bright light and be able to see the light through it. If you can't, then it's time for a new one. Clogged air filters cause your engine to run incorrectly and can decrease mileage if it's not getting enough air into the system.

Step 7

Remove extra weight from the bed of your truck. The less weight you carry the better. Hauling a heavy load slows down your vehicle, thus using more gas to get moving. Only carry extra weight when needed.
