Additionally, Tesla’s regenerative braking system converts kinetic energy back into electricity during deceleration, enhancing battery efficiency while reducing stress on the brake pads. This innovative integration further contributes to the reduced need for frequent component replacements, underscoring the durability and simplicity of Tesla’s engineering. Tesla’s powertrain stands apart from traditional ICE cars, which rely on the combustion of fossil fuels. Instead of an engine with pistons, bearings, and cylinder walls that require lubrication, Tesla and other electric vehicles utilize electric motors. These motors are powered by high-capacity lithium-ion batteries that store and channel electricity to drive the car’s wheels.

An electric motor has fewer moving parts compared to ICE engines, significantly reducing friction and wear. This efficiency eliminates the need for engine oil to lubricate and cool the system. Moreover, Tesla’s regenerative braking system, which converts braking energy back into battery power, further reduces wear and tear on components such as brake pads

Do Teslas Use Oil at All?

Tesla’s electric motors do not require oil for operation, as they lack the complex moving parts found in internal combustion engines. However, certain components of Tesla cars do rely on lubrication to ensure optimal performance:\

Gearbox Oil: Tesla’s drive units, which serve as the equivalent of gearboxes or differentials, utilize synthetic oil for smooth drivetrain operation. The gearbox fluid is crucial for reducing friction and wear within the drivetrain. Tesla recommends changing the gearbox oil every two years for older models.

• For older models like the pre-2021 Tesla Model S and Model X that have gears on the front and rear motors, Tesla previously recommended replacing the transmission fluid every 100,000 miles. This process ensures that the lubricant maintains its viscosity and protective qualities over time, especially under high-stress conditions. The cost of replacing a Tesla's transmission oil is estimated to be around $150 to $200.
• Newer Tesla models feature enhanced oil filtration systems, allowing the lubricant to remain effective for extended periods, often exceeding 100,000 miles without requiring changes. These systems utilize an advanced oil filter to capture debris and impurities, extending the life of the synthetic oil and minimizing the need for intervention.

Grease: Other parts of Tesla vehicles, such as door hinges, latches, and drive axles, require grease to maintain smooth functionality. This type of lubrication is necessary to reduce wear from repeated use and environmental exposure.

• Door Hinges and Latches: These components are subject to frequent movement and must remain lubricated to prevent squeaks and ensure effortless operation. Regular application of high-quality grease ensures their durability.
• Drive Axles: Grease in the drive axle protects against friction and heat buildup during rotation. Routine inspection and replenishment can significantly extend the lifespan of these critical components.

Essential Fluids in Tesla Vehicles

Although Teslas eliminate the need for traditional engine oil, they still require other fluids for optimal performance:

Brake Fluid: Used in hydraulic brake systems, brake fluid can absorb moisture over time, reducing its effectiveness. Brake fluid loses its effectiveness after some time, so Tesla recommends checking and replacing it every two years.

 

Coolant: Tesla’s battery cooling system relies on a specialized coolant to regulate temperature and prevent overheating. Coolant levels should be checked periodically to ensure optimal performance. For efficient energy use and faster charging times, many Tesla owners choose to install a Level 2 charger at home. Most newer Tesla models do not require coolant replacements.

Windshield Washer Fluid: This is essential for maintaining visibility and needs regular refilling, just like in ICE vehicles.

Maintenance Costs: Tesla vs. Traditional ICE Vehicles

One of the standout advantages of owning a Tesla is the significant reduction in maintenance costs compared to traditional internal combustion engine (ICE) vehicles. Here’s an in-depth look at the factors contributing to these savings:

Fewer Moving Parts

Electric motors feature a minimalist design with far fewer components compared to ICE engines. Traditional engines are composed of complex assemblies with pistons, valves, and timing chains that require constant lubrication and occasional replacement. Teslas and other electric cars, by contrast, bypass these issues, resulting in dramatically reduced wear and tear over time.

No Oil Changes

ICE vehicles typically require oil changes every 3,000 to 5,000 miles, with each service ranging from $50 to $100 depending on oil type and labor costs. In contrast, EV owners can start with a Level 1 charger for basic overnight charging, which reduces overall operational expenses significantly. Over the lifespan of a vehicle, these recurring expenses accumulate significantly. By eliminating engine oil entirely, Tesla owners save both time and money, avoiding this traditional maintenance step altogether.

Regenerative Braking

Unlike ICE vehicles, which rely solely on mechanical braking systems, Teslas use regenerative braking to decelerate while simultaneously recapturing energy for the battery. This not only boosts efficiency but also reduces the strain on brake pads, extending their life by years in many cases. The reduced frequency of brake pad replacements adds to the cost savings for Tesla owners.

Longer Component Lifespans

Components such as the drivetrain in Teslas benefit from advanced synthetic oils and filtration systems, requiring less frequent intervention compared to the fluids in ICE vehicles. For instance, Tesla’s synthetic gearbox oil often lasts over 100,000 miles, minimizing long-term maintenance costs.
