Do Electric Vehicles Use Oil?


The simple and short answer is No, but it doesn’t mean that electric cars don’t need oil.

As the popularity of electric cars has been increased in a few years. So with the popularity, the use of electric cars also increased.
Everyone is trying to jump from traditional cars to electric cars but there are many questions related to electric cars, the most important and common question is do electric vehicles use oil.

As other traditional cars use oil to lubricate several moving pieces in their engine so they need oil.
The process is similar to electric cars, electric cars use electric motors instead of oil engines so they don’t need oil.

But we can’t overlook the other tasks of electric cars on which owners must consider. In electric cars, electric motors work similarly to traditional cars.

Do Electric Cars Use Water?

Traditional cars use a water pump to minimize the temperature of the engine but in electric vehicles cooling loop is used to minimize the heat of the electric motor.

Key Components Of Electric Vehicles Which You Should Check Regularly

Although electric cars are very cheap and affordable in the market and we become more pleased to see that EVs need less maintenance but we should check some components of electric vehicles regularly that are followed;


One of the most important parts of electric cars is their battery similar to traditional cars’ internal combustion engine.

In EVs, the battery generates electricity to power the different parts of electric motors to run the electric car.
In electric cars battery takes huge space under the hood(metal protective covering that covers the electric motor).

So like any electric device, we will cover a huge mileage with a single battery.
But most of the electric cars brand contains a single battery so with time the hold of the battery will decrease.

Here you will have two options when the battery is no longer working
1. Return the car to the dealer
2. Replace the battery with a trusted shop

Charge port:

There is a small door like gasoline oil or diesel fuel filler at the front or right/left side of the car called charge port. It is used to plug in the charging cable to charge the electric battery.

DC/DC converter:

The role of DC/DC converter in electric cars is to change DC (direct current) from high voltage(200-800V) into lower DC voltages(12-50V).

This low voltage current is used to power the car’s (EV & HEV) headlights, car’s interior lights, wiper, window motor, fans, and other systems installed in the car.

Traction motor:

The traction motor is the power source in an electric car. It gains electric power from the traction battery pack and provides it to the car wheels.
It gives not only the speed to the car vehicles but also generates power back to the battery when the car uses brakes.

On-Board Charger:

OBCs (onboard charger) is a system that covers Alternative Current(AC) power which comes from external sources (electric pumps)to Direct current (DC) voltage.
This DC voltage is used to charge the battery pack in an electric vehicle. It also performs other functions like charging rate monitor control with the help of a computer and adjusts the charging rate when the battery gets charged.

Thermal system (cooling):

The developed battery thermal management system is a combination of thermoelectric cooling.
Which maintains a proper operating temperature range of the power electronics, electric motor, engine, and other components of electric battery.
The liquid coolant has indirect contact with the battery to remove the heat generated from the battery during operation.

Do electric cars use oil for lubrication?

Do electric cars use oil for lubricant? The answer is simple No. Electric cars don’t use oil for lubrication.
In electric cars, you don’t need to require oil as in traditional cars.
Traditional cars contain internal combustion engines (ICE) which contain valves, pistons, and other components that require oil in the lubrication process when the motor works.

But this is not with electric vehicles. But in Electric vehicles, special fluid is needed to minimize the temperature of the battery in the electric motor.

What fluids do electric cars need? Do electric cars use fluids?

Although electric vehicles don’t need oil change it doesn’t mean that you neglect the maintenance of electric vehicles. You should look out for the maintenance of the electric vehicle regularly. Here are the following fluids that you should check regularly

Battery Coolant

There is an electric motor installed in the electric vehicles instead of an internal combustion engine.
When the electric motor and other components perform work in electric vehicles the temperature of the electric battery becomes increased.
So to minimize the temperature of the battery a special fluid is needed to cool the electric motor. keep the coolant levels high to prevent the battery from overheating in an electric battery.
Tesla Electric vehicles did not recommend any battery coolant fluid replacement for their electric vehicles but Chevy Bolt recommended a battery coolant fluid replacement after 1,50,000 miles(2,41,401.6 km).

Transmission Fluid

The electric vehicles run on electric batteries and drive electric motors which have only one gear or more in some models.                                                                                                                                                                                           Therefore with no shifting between gears, EVs require no motor oil to lubricate the gears. In EVs, there is a transmission system that needs fluid for maintenance. This fluid is special and therefore users can not replace it by themselves.

Brakes Fluid

Electric vehicles contain brake fluid (which is called Hydraulic Fluid ) like other traditional gasoline cars. So brakes fluid need regular maintenance for better working of brakes. In electric vehicles, brakes are used less frequently because of regenerative braking.
Because regenerative braking allows the electric vehicles to send energy back to the battery as it slows the EVs down. You can change the brakes fluid when needed because it is not necessary to change the brakes fluid regularly.
For traditional gasoline cars, brakes fluid can be changed between two to five years or every 20,000 miles(32,186.88km), and for electric cars like the Tesla brand, electric vehicles recommend brake fluid changes every five years.

Windshield Washer Fluid

Electric vehicles also need other fluids like Windshield washer fluid.
The windshield washer fluid is used in both EVs and Traditional gas cars.
The windshield fluid applies to steering fluid (for vehicles with hydraulic power steering), air conditioning fluid, grease for suspension systems, door locks, wheel bearings, and other small moving parts of vehicles(EVs & gas-powered cars).

Will Electric Cars Kill the Oil Industry(Gasoline vs Electricity)

The answer is yes! This is because of the low cost of electric battery charging as compared to gasoline oil. The EVs user cost savings are the greatest of the gasoline car user. Therefore when the use of oil will become low the electric vehicles automatically kill the oil industry.
According to Bloomberg New Energy Finance, the same battery that cost $1,000 in 2010 will cost $73 in 2030. By that point, the total cost of a new electric car will be well below gas-powered vehicles.


Research related to EVs and the Gasoline oil industry


The U.S. Department of Energy said that: “The cost to run your [electric] car over a year can be less than running an air conditioner.”
According to a 2020 study from Consumer Reports, electric vehicles “were estimated to save consumers about 60% on fuel costs compared with the average vehicle in their class.
Electric vehicles will kill the global oil industry by 2030, says Stanford Economist Tony Seba – Thoughtful Journalism About Energy’s Future.
By 2040, electric cars would eliminate the need for 8.5 million barrels of oil per day, Bloomberg estimates. That figure is the equivalent of the output of Saudi Arabia.                                                         
According to Seba’s projections, the average American would save $5,600 by operating without a car and depending on autonomous EVs for necessary travel.
The study also points out that if the age of EVs is more, the savings of the owner of that particular electric vehicle will be more as the efficiency of an electric motor decrease slowly as compared to a gas-powered engine whose efficiency decreases quickly.
A five- to seven-year-old used EV saves two to three times more in fuel costs than a comparable gas-powered vehicle.
The study estimated that electric vehicle owners could save between $6,000 to $10,000 over the life of a vehicle.

How Do Electric Engines Work?

In electric vehicles, an electric battery is installed which stored electricity to power electric motors to turn their wheels.

Electric cars engine

when the battery becomes empty you can recharge the electric battery through electric pumps. Electric charging stations are growing day by day in the world.
The electric motor consist of magnets that convert the electrical current into the mechanical current.
Electrical currents are moving streams of charged particles that make their magnetic field, as do magnets on the other side of the electric motor.
When these fields interact, they result in a twisting force known as torque, thus the stronger the electrical current, the more mechanical power the electric motor will generate.
This mechanical rotation is distributed to a car’s wheels, in the same way, a traditional car, which means all vehicles powered by an electric motor can drive just as if they were powered by gas or diesel.

Maintenance Of An Electric Vehicle?

The maintenance of an electric vehicle varies from model to model and depends on the electric battery. Here are some points which are very important for EV maintenance;

Monitor the battery

The battery is the most important component in the EVs which drive the whole system in the car. So you should monitor the performance of the battery regularly and charge it properly up to 80%.

The brake system

In electric vehicles, the brake system works differently as compared to traditional vehicles.
So it is important to check them properly especially in the areas of snow and where road salt is used for winter road maintenance.

Check tires

As we know that tires are also more important in the maintenance of EVs as well as traditional vehicles. So, Regardless of what type of vehicle you have, checking tires is an essential part of any car.                                  Checking tires regularly will be beneficial in the long term to not replace them too often. Also, checking the tires will provide a better driver overall, and most importantly a safe drive.
It is very important to install the correct size and brand of tire with good specifications to maintain proper handling and safety of the car and yourself.

Mostly the lifespan of a tire is 6 years regardless of tread wear. But We recommend aligning your wheels every 6-12 months for tire longevity.

Electric Car Fluids

As we mentioned earlier, electric cars have heavy batteries that cannot be overheated or underheated.
To prevent that from happening, it’s essential to manage the liquid thermal management system.
So it is important to check EVs fluid regularly.
And also don’t forget about the break builds and windshield wiper fluid. These fluids require the same attention as any type of fluid.

Replace Cabin Air Filter

We use EVs to reduce the pollution in our environment, so it is necessary to clean your vehicle.
Therefore it is very important to change the car cabin filter to prevent pollution in the car.
It is a very affordable and simple way to stay healthy while driving.

Maintenance Similarities Between EVs And Gas Powered Cars

Though there is a huge difference in EVs and Gas-powered cars design and function we need regular maintenance of both vehicles.
The biggest similarity between EVs and Traditional Cars is Cabin air filters.
The cabin air filters block the harmful particles from getting into the interior of the vehicle.
The cabin filters in both types of vehicles need to be replaced when it is necessary to maintain healthy air and prevent pollution in the cars.
