2018 Tesla Model 3 Oil Capacity & Filter Reference

A 2018 Tesla Model 3 requires 0 quarts of engine oil, as it is a fully electric vehicle (EV) and does not have an internal combustion engine that would require motor oil.

Quick Answer: This EV Doesn't Take Oil!

As an ASE-certified technician, this is one of the easiest specs to remember! Because the 2018 Tesla Model 3 is a pure electric vehicle, it has no engine, no oil pan, and no need for a traditional oil change. Here are the "specs" you came for:

• Engine Oil Capacity: 0 quarts / 0 Liters
• Recommended Oil Weight: None / Not Applicable
• Oil Specification: N/A
• Oil Filter: N/A

Capacity by Engine Option

Unlike gasoline-powered cars, all 2018 Tesla Model 3 variants (Standard Range, Mid Range, Long Range, Performance) are fully electric. None of them contain an internal combustion engine.

Engine/Motor Option	Oil Capacity (Quarts)
All Electric Motors	0

So, What Fluids Does It Need?

While you'll save a lot of time and money by skipping oil changes, your Model 3 is not maintenance-free. It contains several important fluids that require inspection and periodic replacement to ensure long-term reliability of the battery, brakes, and drive units.

Brake Fluid

This is the most critical fluid you'll need to change. Tesla recommends testing the brake fluid for contamination every 2 years and replacing it as needed. Moisture intrusion can lower the boiling point of the fluid, leading to a spongy pedal or loss of braking power in an emergency.

• Recommended Interval: Every 2 years or 25,000 miles (test and replace if needed)
• Fluid Type: DOT 3 or DOT 4 Brake Fluid (Consult your service manual, but DOT 3 is standard)

Battery Coolant

Your Tesla has a sophisticated thermal management system to keep the battery pack at its optimal operating temperature. This system is filled with a special long-life coolant.

• Recommended Interval: Every 4 years or 50,000 miles
• Fluid Type: Tesla G-48 Ethylene Glycol Coolant (Blue)

Drive Unit Fluid(s)

The front and rear drive units each contain their own lubricating fluid, similar to a differential or transmission fluid. Tesla considers this a "lifetime" fluid that does not require changing under normal circumstances. However, some high-mileage owners or independent repair shops may recommend a fluid change after 100,000 miles as a preventative measure.

How to Change the... Cabin Air Filter

You can't change the oil, but one of the most common DIY jobs on a Model 3 is replacing the cabin air filter, which cleans the air coming into the passenger compartment.

1. Access the Filter: The filter is located in the front passenger footwell area, requiring the removal of a few trim panels.
2. Remove Old Filter: Carefully pull the old filter assembly out.
3. Install New Filter: Slide the new filter in, ensuring the airflow direction is correct.
4. Reassemble: Replace the trim panels.

Tesla recommends replacing this filter every 2 years.

Common Issues / Tips for the 2018 Model 3

• Use Jack Pucks: NEVER lift a Tesla Model 3 without using proper "jacking pucks." These are placed into specific holes in the chassis to provide a safe lifting point. Lifting directly on the rocker panel or underbody can cause catastrophic damage to the high-voltage battery pack.
• Brake Maintenance: Due to powerful regenerative braking, the hydraulic brake pads and rotors on a Model 3 see much less use than on a gas car. This can cause slide pins to seize and pads to stick, especially in regions that use road salt. We recommend a full brake service (cleaning and lubricating caliper slide pins and hardware) every 1-2 years to ensure they work when you need them.
• Control Arm Bushings: Early Model 3s were known for developing a creaking or squeaking noise from the front upper control arms, especially in cold weather. This is often due to a faulty bushing design. Tesla has since issued revised parts to correct this.
