If your fuel consumption suddenly alters while you have not changed very much in your driving habits, there is necessarily something to verify and this quickly because it can cost you a lot more.
in this article, we will expose you to the most common motives that can cause your car to consume more fuel in order to help you recognize the one that concerns you.


Causes of a Mercedes Benz GL Class that consumes too much:

the tires of your Mercedes Benz GL Class:

if they are underinflated, you will consume more. take into account to watch out for this, but don’t over inflate them, they could burst at full speed.
also, if you still have winter tires, this may likely explain your over-consumption. especially if they are old or of poor level of quality. recent winter tires are normally much more economical in terms of fuel consumption. the old ones are equipped with much thicker slats that cause overconsumption.

energy-intensive equipment:

your air conditioning makes use of a lot of energy. use it only in case of high heat and do not be too demanding for the temperature of your Mercedes Benz GL Class. if possible, roll with the windows open. in a logical way, when you can, try to park your car in the shade.
also, try to use lighter colours for the interior of your car, which attract less heat.

template of your Mercedes Benz GL Class:

your Mercedes Benz GL Class, when it rolls, has a certain grip in the wind. limit possible brakes such as equipment on your roof as much as possible. racks, a roof box… anything that may have some grip on the wind, even minimal. think about every detail.
the same is true to any significant equipment not expected in your Mercedes Benz GL Class.
your spare wheel, for example, is no longer really required nowadays. it is relatively heavy, and is instantly replaceable by a puncture-proof bomb that is very effective.

electrical accessories of your Mercedes Benz GL Class:

any superfluous material can lead to an increase in fuel consumption. heated seats, a sound system that is far too loud, windshield wipers, etc. anything that is not vital consumes fuel when you don’t necessarily want it. it is up to you to evaluate your priorities.

air filter:

if it were blocked, it would reduce power and would need to overcompensate by consuming more. keep an eye on it often and ensure that it is well maintained.

brakes of your Mercedes Benz GL Class:

their role is to brake your Mercedes Benz GL Class when you want by using the pedal. but what happens if they continue to brake your vehicle, even very just a little, when you no longer depress the brake pedal? in certain instances it is possible to hear it in the ear (slight hissing) but generally it is inaudible.
to make sure, you must raise your car to turn the wheels by hand. you will have to do the test on all four wheels. to raise your car, proceed with a jack as if you were changing a tire. once raised, try to turn your wheel by hand and listen. all four wheels must of course turn without any noise or braking, all in a fair way. you have the opportunity to compare the four and detect a potential problem.


if it were more viscous than usual, you would increase your consumption. this still has the advantage of protecting old engines. if your Mercedes Benz GL Class is new, you can then make use of a more fluid oil, maintaining the manufacturers’ recommendations. identify more about this before you act.
no matter what you do, don’t combine the oils and don’t add anything. you would risk modifying the chemical reactions which always can have repercussions on your Mercedes Benz GL Class, and especially you were no longer under warranty by the manufacturer.

ignition and carburation settings of your Mercedes Benz GL Class:

observe the colour of your smoke. if this one wasn’t light grey, there’s probably a problem.
the same is true to the power of your Mercedes Benz GL Class. if all of a sudden you lose power, then gain it again, your engine may overcompensate by over-consuming because there is a breakdown.


if your Mercedes Benz GL Class has candles, check they are in good condition. their mission is to ignite the fuel and thus ensure combustion in order to create energy. if they were not in excellent condition, this would result in poor combustion in the combustion chamber, which contributes to a waste of fuel.
take into account to clean them and replace them if necessary.

here are the main reasons that could lead your Mercedes Benz GL Class to consume more. of course, your driving will be the most significant factor in determining your consumption. avoid sudden accelerations and “sporty” driving and you will regain normal fuel consumption.
