Do Electric Cars Use Oil? Understanding the System

Many people have become interested in switching to electric vehicles in recent years. As a result, many people have basic questions, such as, "Do electric cars use oil?"

This is a reasonable question, especially for those accustomed to gasoline-powered vehicles that require regular oil changes.

So, do electric cars use oil? The following article provides a clear answer.

Do Electric Cars Use Oil?

Electric cars do not use engine oil like gasoline-powered vehicles. They lack internal combustion engines, so there is no need for oil to lubricate pistons, crankshafts, or valves.

However, electric cars still contain mechanical components, such as electric motors, gearboxes, and cooling systems, that require lubricants.

In electric cars, lubricants are primarily used in the transmission and cooling systems. These lubricants reduce friction, prevent excessive heat, and minimize component wear.

Types of Lubricants Used in Electric Cars

Below are the main types of lubricants commonly used in modern electric vehicles.

1. Transmission Oil (Reduction Gear Oil)

Although electric cars do not have complex transmissions with multiple gear ratios like conventional cars, they still rely on a gearbox or reduction gear. Its function is to reduce the extremely high rotation speed of the electric motor into a proportional torque rotation suitable for smoothly driving the wheels.

This process creates friction between gears, so transmission oil is used to lubricate, prevent wear, and reduce noise at high speeds.

The good news is that transmission oil replacement intervals in electric cars are very long. In fact, it usually only needs to be replaced after about 100,000 kilometers, depending on the manufacturer's recommendation.

2. Thermal Management Coolant

Coolant is one of the most vital lubricants within the electric vehicle ecosystem. The large lithium-ion battery, which serves as the heart of the vehicle, is extremely sensitive to temperature fluctuations.

If it overheats during high-speed driving or fast charging, its performance can decrease drastically and risk permanent cell damage. On the other hand, if it becomes too cold, efficiency and driving range can also decrease.

That is why specialized EV coolant is extremely important. This fluid circulates through an integrated cooling system surrounding the battery modules, inverter, and electric motor to maintain optimal operating temperatures.

3. Brake Fluid and Regenerative Braking Systems

Electric cars use regenerative braking. When you release the accelerator pedal, the electric motor reverses its function, acting as a generator to create an engine-braking effect while simultaneously converting kinetic energy back into battery power.

As a result, conventional hydraulic brakes are used less frequently. So, electric vehicle brake pads tend to last much longer and can remain durable for years.

However, the hydraulic braking system remains essential for emergencies, so brake fluid quality, volume, and pressure should be checked regularly.

4. General Mechanical Lubricants

Electric cars also use grease lubricants for heavy-load mechanical areas, including wheel bearings, door hinges, wiper mechanisms, and suspension components.

In summary, while electric cars do not use engine oil, they still require lubricants, though in a more efficient and environmentally friendly manner.

The Massive Environmental Impact of Reduced Oil Consumption

Switching to electric vehicles has a positive environmental impact. This is because moving toward electrified vehicles means significantly reducing the consumption and waste associated with fossil-based lubricants.

The implications are highly positive and include several major benefits, such as:

• Reduction of Hazardous Waste Volume: The volume of hazardous liquid waste generated by daily automotive maintenance can be reduced significantly.
• Conservation of Natural Resources: Reduced dependence on oil drilling activities that damage natural habitats.
• Lower Carbon Footprint Across Supply Chains: Decreasing greenhouse gas emissions generated from oil refining processes, plastic bottle packaging production, and lubricant distribution logistics to thousands of workshops nationwide.
  
  

The Relevance of Electric Vehicle Usage to Astra Net Zero Scope 1 & 2 Initiatives

As a company that also operates in the automotive industry, Astra continues striving to reduce operational impacts and neutralize carbon emissions from the electric vehicles it provides.

Several strategic pillars of the Astra Net Zero Scope 1 & 2 initiative for 2050 are directly connected to the electrification vehicle revolution, including:

1. Future of Mobility Pillar

Astra continuously innovates by expanding its electrified vehicle portfolio. By marketing a range of advanced models, from Hybrid Electric Vehicles (HEV) and Plug-in Hybrid Electric Vehicles (PHEV) to Battery Electric Vehicles (BEV), Astra actively provides consumers with real options to help reduce greenhouse gas emissions in the land transportation sector.

2. Astra 2030 Sustainability Aspirations

As part of its medium-term milestones, Astra has set a target to reduce Scope 1 and 2 greenhouse gas emissions by 30% by 2030, calculated from the 2019 baseline.

Each electric vehicle driven, by eliminating fossil fuel use and routine engine oil waste, directly contributes to achieving this target.

3. Astra Green Company (AGC) Implementation

Astra ensures that all business lines under its ecosystem, including after-sales service facilities and authorized workshop networks, comply with Astra Green Company's environmental management protocols.

Any waste from electric vehicle maintenance, such as battery coolant or transmission oil, will be handled, recycled, or managed through high-standard hazardous waste treatment facilities to ensure environmental sustainability.
