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 use up more. bear in mind 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 explain your over-consumption. specifically if they are old or of poor level of quality. recent winter tires are normally much more low-priced 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 when considering the temperature of your Mercedes Benz GL Class. if possible, roll with the windows open. of course, 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 could have grip on the wind, even minimal. think about every detail.
the same applies to any significant equipment not expected in your Mercedes Benz GL Class.
your spare wheel, for example, is no longer really important nowadays. it is quite heavy, and is instantly replaceable by a puncture-proof bomb that is very effective.

electrical accessories of your Mercedes Benz GL Class:

any unneeded material can result in an increase in fuel consumption. heated seats, a sound system that is far too loud, windshield wipers, etc. anything that is not important 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 have to overcompensate by consuming more. keep an eye on it often and make sure 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 pressing the pedal. but what happens if they continue to brake your vehicle, even very slightly, when you no longer depress the brake pedal? in certain instances you’ll be able 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 boost your consumption. this still has the advantage of protecting old engines. if your Mercedes Benz GL Class is new, you can then use a more fluid oil, respecting the manufacturers’ recommendations. identify more about this before you act.
regardless of you do, don’t blend the oils and don’t add anything. you might risk altering the chemical reactions which 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. in the event this one wasn’t light grey, there’s most likely a problem.
the same applies 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 failure.


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 perfect condition, this would result in poor combustion in the combustion chamber, which leads to to a waste of fuel.
keep in mind 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 important factor in determining your consumption. avoid sudden accelerations and “sporty” driving and you will restore normal fuel consumption.
