the tires of your Toyota Corolla:

if they are underinflated, you will consume more. remember 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 could 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 induce 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 Toyota Corolla. 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 Toyota Corolla:

the same is true to any heavy equipment not required in your Toyota Corolla.
your spare wheel, for example, is no longer really required nowadays. it is fairly heavy, and is quickly replaceable by a puncture-proof bomb that is very effective.

electrical accessories of your Toyota Corolla:

any unneeded material may result in an increase in fuel consumption. heated seats, a sound system that is far too loud, windshield wipers, etc. anything that is not essential consumes fuel when you don’t necessarily need it. it is up to you to determine your priorities.

brakes of your Toyota Corolla:

their role is to brake your Toyota Corolla when you want by pressing the pedal. but what if they continue to brake your vehicle, even very just a little, 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 nonetheless has the advantage of preserving old engines. if your Toyota Corolla is new, you can then make use of a more fluid oil, respecting the manufacturers’ recommendations. find out more about this before you act.
no matter what you do, don’t blend the oils and don’t add anything. you would risk altering the chemical reactions which always can have repercussions on your Toyota Corolla, and especially you were no longer under warranty by the manufacturer.

ignition and carburation settings of your Toyota Corolla:

check out the colour of your smoke. if it turns out this one wasn’t light grey, there’s almost certainly a problem.
the same is true to the power of your Toyota Corolla. if suddenly you lose power, then gain it again, your engine may overcompensate by over-consuming because there is a malfunction.


if your Toyota Corolla comes with candles, check they are in good condition. their task is to ignite the fuel and consequently ensure combustion in so that it will create energy. if they were not in perfect condition, this would end in mediocre combustion in the combustion chamber, which provides to a waste of fuel.
remember to clean them and replace them if necessary.
