Causes of a Nissan Altima that consumes too much:

the tires of your Nissan Altima:

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 economical in terms of fuel consumption. the old ones are equipped with much thicker slats that cause 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 with regard to the temperature of your Nissan Altima. 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 Nissan Altima:

your Nissan Altima, 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 very low. think about every detail.
the same applies to any major equipment not needed in your Nissan Altima.
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 Nissan Altima:

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

air filter:

if it were blocked, it would lose power and would need to overcompensate by consuming more. check on it often and make sure it is well maintained.

brakes of your Nissan Altima:

their role is to brake your Nissan Altima 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 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 nonetheless has the advantage of preserving old engines. if your Nissan Altima 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 mix the oils and don’t add anything. you might risk modifying the chemical reactions which can have repercussions on your Nissan Altima, and especially you were no longer under warranty by the manufacturer.

ignition and carburation settings of your Nissan Altima:

watch the colour of your smoke. if this one wasn’t light grey, there’s almost certainly a problem.
the same applies to the power of your Nissan Altima. if suddenly you lose power, then gain it again, your engine may overcompensate by over-consuming because there is a breakdown.


if your Nissan Altima comes with candles, make certain they are in good condition. their task is to ignite the fuel and thus ensure combustion in so that it will create energy. if they were not in suitable condition, this would end in poor combustion in the combustion chamber, which provides 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 Nissan Altima 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.
