If your fuel consumption suddenly alters although you have not changed noticeably in your driving practices, there is always 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 detect the one that concerns you.


Causes of a Hyundai Elantra that consumes too much:

the tires of your Hyundai Elantra:

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 likely explain your over-consumption. specifically if they are old or of poor 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 motive overconsumption.

energy-intensive equipment:

your air conditioning uses a lot of energy. use it only in case of high heat and do not be too demanding when considering the temperature of your Hyundai Elantra. 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 Hyundai Elantra:

your Hyundai Elantra, 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 very low. take into account every detail.
the same can be applied to any heavy equipment not needed in your Hyundai Elantra.
your spare wheel, for example, is no longer really required nowadays. it is quite heavy, and is easily replaceable by a puncture-proof bomb that is very effective.

electrical accessories of your Hyundai Elantra:

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 important consumes fuel when you don’t necessarily need it. it is up to you to evaluate your priorities.

air filter:

if it were clogged, it would reduce power and would have to overcompensate by consuming more. check on it often and ensure that it is well maintained.

brakes of your Hyundai Elantra:

their role is to brake your Hyundai Elantra 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 some cases 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 amplify your consumption. this still has the advantage of preserving old engines. if your Hyundai Elantra is new, you can then use a more fluid oil, respecting the manufacturers’ recommendations. identify more about this before you act.
whatever you do, don’t blend the oils and don’t add anything. you would risk modifying the chemical reactions which always can have repercussions on your Hyundai Elantra, and especially you were no longer under warranty by the manufacturer.

ignition and carburation settings of your Hyundai Elantra:

observe the colour of your smoke. in the event this one wasn’t light grey, there’s almost certainly a problem.
the same can be applied to the power of your Hyundai Elantra. if all of a sudden you lose power, then gain it again, your engine may overcompensate by over-consuming because there is a malfunction.


if your Hyundai Elantra has candles, make sure 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 suitable condition, this would result in mediocre combustion in the combustion chamber, which provides 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 Hyundai Elantra 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.
