Causes of a Cadillac CTS that consumes too much:

the tires of your Cadillac CTS:

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. specifically 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 with regard to the temperature of your Cadillac CTS. 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 Cadillac CTS:

your Cadillac CTS, 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 minimal. think about every detail.
the same applies to any significant equipment not required in your Cadillac CTS.
your spare wheel, for example, is no longer really required nowadays. it is relatively heavy, and is instantly replaceable by a puncture-proof bomb that is very effective.

electrical accessories of your Cadillac CTS:

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

brakes of your Cadillac CTS:

their role is to brake your Cadillac CTS when you want by pressing the pedal. but what if they continue to brake your vehicle, even very slightly, when you no longer depress the brake pedal? in some cases 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.

oil:

if it were more viscous than usual, you would boost your consumption. this however has the advantage of preserving old engines. if your Cadillac CTS 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 can have repercussions on your Cadillac CTS, and especially you were no longer under warranty by the manufacturer.

ignition and carburation settings of your Cadillac CTS:

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

candles:

if your Cadillac CTS has candles, check they are in good condition. their objective 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 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 Cadillac CTS 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 restore normal fuel consumption.
