As an all-electric vehicle, the 2021 Tesla Model 3 does not have an internal combustion engine and therefore does not require traditional engine oil changes.
Quick Answer: No Oil Change Needed
The 2021 Tesla Model 3 is a fully electric vehicle (EV). It does not have a gasoline engine, which means:
- Engine Oil Capacity: 0 quarts / 0 liters. There is no engine oil.
- Recommended Oil Weight: Not applicable.
- Oil Specification: Not applicable.
- Oil Filter: Not applicable. There is no oil filter to replace.
Understanding Your Model 3's Fluids
While your Model 3 doesn't need oil changes, it does have other fluids that require inspection and replacement at specific intervals. These are typically checked during routine service visits.
- Battery Coolant: A critical fluid that manages the temperature of the high-voltage battery. Tesla specifies a replacement interval of every 4 years or 50,000 miles, whichever comes first.
- Brake Fluid: Like any car, the brake fluid needs to be checked and replaced. The recommendation is to test it for contamination every 2 years and replace as necessary.
- Cabin Air Filter: This is not a fluid, but it's a common maintenance item. The cabin air filter should be replaced every 2 years.
There is no user-serviceable engine, transmission, or differential fluid to change in a Model 3.
Service and Maintenance
Instead of oil changes, service for a Model 3 focuses on tire rotation, brake health, cabin air filter replacement, and A/C service. All fluid and maintenance schedules are outlined in your owner's manual and accessible through the Tesla app or your vehicle's touchscreen.
For any service needs, it is recommended to schedule an appointment through the Tesla app or visit a Tesla Service Center.
