Causes of a Chevrolet Silverado that consumes too much:

the tires of your Chevrolet Silverado:

if they are underinflated, you will use up 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 may 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 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 for the temperature of your Chevrolet Silverado. 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 Chevrolet Silverado:

your Chevrolet Silverado, 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. take into account every detail.
the same is true to any major equipment not required in your Chevrolet Silverado.
your spare wheel, for example, is no longer really necessary nowadays. it is relatively heavy, and is instantly replaceable by a puncture-proof bomb that is very effective.

electrical accessories of your Chevrolet Silverado:

any superfluous 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 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 reduce power and would have to overcompensate by consuming more. check on it often and ensure that it is well maintained.

brakes of your Chevrolet Silverado:

their role is to brake your Chevrolet Silverado when you want by using the pedal. but what happens 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 boost your consumption. this nonetheless has the advantage of protecting old engines. if your Chevrolet Silverado is new, you can then work with a more fluid oil, maintaining the manufacturers’ recommendations. identify more about this before you act.
regardless of you do, don’t mix the oils and don’t add anything. you might risk altering the chemical reactions which always can have repercussions on your Chevrolet Silverado, and especially you were no longer under warranty by the manufacturer.

ignition and carburation settings of your Chevrolet Silverado:

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


if your Chevrolet Silverado has candles, make certain they are in good condition. their objective 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.
remember to clean them and replace them if necessary.

here are the main reasons that could lead your Chevrolet Silverado 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 regain normal fuel consumption.
