If your fuel consumption suddenly alters although you have not changed noticeably in your driving practices, there is always something to verify and this right away because it can cost you a lot more.
in this article, we will introduce 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 Kia Soul that consumes too much:

the tires of your Kia Soul:

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. especially 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 induce 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 Kia Soul. if possible, roll with the windows open. logically, 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 Kia Soul:

your Kia Soul, 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 would have grip on the wind, even very low. take into account every detail.
the same can be applied to any heavy equipment not expected in your Kia Soul.
your spare wheel, for example, is no longer really important nowadays. it is relatively heavy, and is instantly replaceable by a puncture-proof bomb that is very effective.

electrical accessories of your Kia Soul:

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 need it. it is up to you to determine your priorities.

air filter:

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

brakes of your Kia Soul:

their role is to brake your Kia Soul when you want by using the pedal. but what if they continue to brake your vehicle, even very moderately, 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 amplify your consumption. this however has the advantage of protecting old engines. if your Kia Soul is new, you can then use a more fluid oil, maintaining the manufacturers’ recommendations. identify more about this before you act.
whatever you do, don’t combine the oils and don’t add anything. you might risk altering the chemical reactions which usually can have repercussions on your Kia Soul, and especially you were no longer under warranty by the manufacturer.

ignition and carburation settings of your Kia Soul:

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


if your Kia Soul comes with candles, make sure they are in good condition. their objective is to ignite the fuel and consequently 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 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 Kia Soul 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.
