The improvements in fuel efficiency of your Mercedes Benz will save money on the pump as well as lower your car's impact on the environment. Luckily, to do all this, one does not need any special tools or complicated procedures to be done to the car to make it run more efficiently.
Here is a simple guide to assist you in getting the most from every gallon of fuel.
Arguably, the most convenient ways of improving fuel efficiency relate to making sure your tyres are properly inflated. If properly inflated, tyres would provide greater rolling resistance and, hence, make the work of your engine more difficult by pumping extra fuel. The habit of looking in on the tyre pressure should be kept at least monthly, keeping it inflated to recommended levels mentioned in the owner's manual of your vehicle or inside the driver's side door on a sticker.
Spark plugs ignite the fuel-air mixture inside your engine. After some time, they wear out or get dirty and cause incomplete combustion, hence reducing fuel efficiency. Replace your spark plugs according to your Mercedes-Benz service schedule from 30,000 to 50,000 miles apart to ensure the engine is smooth and has good fuel economy.
Now, the air filter should always be clean for an engine's improved performance. It helps the engine get the right amount of clear air that is required for its combustion. When this air filter becomes clogged up or dirty, the flow of air will be restricted, and the engine consequently will be put under further strain, which will lead to its increased fuel consumption. All of this usually needs to be replaced every 12,000 to 15,000 miles or whatever mile interval the manufacturer of your car suggests.
Misaligned wheels can pull your car to one side or create uneven tyre wear that increases rolling resistance hence increasing fuel consumption. Regular checking and adjustment of wheel alignment prevent the uneven wear and tear of the tyres, which in turn increases fuel efficiency. Have the alignment checked in case you experience problems with the steering or uneven wear and tear of the tyres.
If your car is supposed to have a rear spoiler and it gets either damaged or lost, it affects the car's aerodynamics; in other words, increases fuel consumption. However, a fully integrated spoiler can do much to reduce the drag created by aerodynamics since the air running over your car is in turmoil. So, in case of a damaged spoiler, you would want to look into its replacement for the increased inbuilt aerodynamic impact, which saves your fuel.
Basically, the oxygen sensors track down the availability of oxygen in the waste gases and enable the engine to regulate the mixture of air and fuel properly. If the oxygen sensors go bad, combustion of fuel may not be apt, and thus fuel starts consuming more than usual consumption. They are those kinds of parts that proper working is a must if the running of the engine is to be done properly. For this, one must replace them on time.
It regulates the coolant temperature of your vehicle. If this becomes corrupted, then you're sure to face one of two extremes: an overheated or an overcooled engine. This also affects fuel economy. Replace it if you notice that your temperature gauge fluctuates excessively or if it's taking longer than usual for your car to heat up.
Although the cabin air filter does not directly influence performance, it is quite helpful in maintaining quality air inside your vehicle. A clean cabin air filter allows the air conditioning to work with at least possible inefficiency, which again influences fuel consumption indirectly. This needs replacement regularly after every 15,000 to 20,000 miles.
Dragging or partially applied brakes introduce friction to your engine, making it burn more fuel. You can prevent this by periodically having your brakes inspected if you suspect they are sticking or dragging. Good brakes mean smooth driving and better economy.
More importantly, a regular oil change keeps the owner informed about the efficiency of the engine of the vehicle. Fresh, clean oil reduces friction among moving parts of the engine and gives way to the smooth running of the motor, hence yielding a better economy in fuel. Do regularly change the oil, so it should be every 5,000 to 7,500 miles, or whenever the manufacturer recommends, whichever of the two comes earlier, except when you drive under extreme conditions.
Other than this, the maintenance tasks are keeping up with these and making little adjustments that will serve to improve fuel efficiency in your Mercedes-Benz. Besides saving you money at the pump, it's also going to keep your vehicle running longer. What you want is regular maintenance so that your car is always at its best. Follow these to make it part of your routine.
