If you’re eyeing a Tesla, especially a used one, you’ve probably heard the siren song: no oil changes ever. It sounds almost mythical, like a car that runs on vibes and podcast ads. So, does Tesla use oil at all, or is that just marketing shorthand? Let’s separate the engineering from the folklore.
Quick takeaway
Teslas do not use engine motor oil and do not need traditional oil changes. But they do use other oils and fluids, like gearbox oil, brake fluid, and coolant, that matter for long‑term reliability, especially on a used car.
Short answer: does a Tesla use oil?
In the way most people mean the question, "Does it have engine oil and need oil changes?", the answer is no. Teslas don’t have internal combustion engines, so there’s no motor oil, no oil filter, and no 5,000‑mile ritual at a quick‑lube shop.
- No engine = no motor oil.
- No motor oil = no traditional oil changes, ever.
- You’ll still have a handful of other fluids that age and sometimes need to be serviced.
Think of it this way
A Tesla trades dozens of engine parts and regular oil changes for an electric motor, a reduction gearbox, and a big battery pack. Less to service, but what’s left becomes more important to check when you’re buying used.
Why gas cars need oil, and Teslas don’t
Gasoline engine: a heat machine
A traditional engine is a small metal war zone: pistons racing up and down, valves opening and closing, fuel exploding dozens of times per second. All of that creates heat, friction, and microscopic metal shavings.
Motor oil’s job is to:
- Lubricate all those moving parts
- Carry away heat
- Trap contaminants and combustion byproducts
Over time the oil breaks down and gets dirty, so it must be drained and replaced on a schedule.
Electric motor: a physics trick
A Tesla’s electric motor has far fewer moving parts. It makes power using electromagnetic fields, not explosions. The rotor spins inside the stator, supported by sealed bearings that are lubricated for life.
There’s no fuel, no combustion, no motor oil. The main sources of wear shift from the engine to things like tires, suspension bushings, and, long term, battery health.
The upside for you
With no engine oil, spark plugs, fuel injectors, or exhaust system, an electric vehicle like a Tesla typically costs thousands less to maintain over its lifetime than a comparable gas car. That’s one reason used Teslas can make so much sense, if the battery and fluids check out.
What fluids do Teslas actually use?
“No oil changes” doesn’t mean “no fluids.” Tesla’s own service manuals list several critical fluids in modern Model 3, Model Y, and Cybertruck vehicles, and they all affect longevity when you’re looking at a used example.
Key fluids in a Tesla (and what they do)
These are the main fluids you should know about if you own, or are about to buy, a Tesla.
| System | Does it use oil or fluid? | Serviceable by owner? | Typical concern on a used Tesla |
|---|---|---|---|
| Engine oil | No | N/A | Never changed because it doesn’t exist |
| Drive unit gearbox | Yes – specialized gearbox oil | No, typically service-center job | Potential wear if fluid is contaminated or never serviced in high‑mileage cars |
| Battery & power electronics cooling | Yes – ethylene glycol–based coolant | Rarely; usually service-center | Coolant age, leaks, or mixing incompatible coolants on repaired cars |
| Brakes | Yes – DOT 3/4 brake fluid | Sometimes, with proper tools | Old fluid absorbing moisture, especially in humid climates |
| Windshield washer system | Yes – washer fluid | Yes | Low fluid, clogged nozzles |
| Air conditioning | Yes – refrigerant and compressor oil | No | Leaks, weak A/C on older or high‑mileage cars |
Teslas skip engine oil, but they still rely on specialized fluids to keep braking, cooling, and driveline systems healthy.
Don’t ignore “invisible” fluids
Because Teslas don’t nag you for oil changes, it’s easy to assume nothing ever needs attention. But aged brake fluid, neglected gearbox oil, or botched coolant work can all shorten the life of components that aren’t cheap to replace.
Wait, so does a Tesla have gear oil?
Here’s where the nuance comes in. While there’s no engine oil, Tesla’s drive units do use gearbox oil to lubricate the reduction gears and differential that send power to the wheels. In Tesla service manuals for late-model Model 3 and Model Y, you’ll see a dedicated Gearbox Fluid section with refill capacities for the front and rear drive units.
Tesla drive unit & gearbox: what matters
Tesla originally marketed many driveline fluids as “lifetime fill”, but in practice, high‑mileage or hard‑driven cars sometimes benefit from a gearbox oil service. The oil also helps carry heat away from internal components, so clean fluid isn’t just about friction, it’s about temperature control.
Gear oil vs. motor oil
Gearbox oil is not the same as engine motor oil. It’s a different formulation, used in a closed reduction gear housing, and it’s never something you take to a quick‑lube shop. It’s specialist work, usually done at a Tesla Service Center or a qualified EV shop.
Tesla maintenance vs. gas car maintenance
To understand what “no oil” actually saves you, it helps to compare the maintenance rhythm of a modern gas car with that of a Tesla. If you’re cross‑shopping a used Camry and a used Model 3, this is where the math moves from theoretical to very real.

Maintenance: Tesla vs. typical gas car
What you’ll stop doing, and what stays on the to‑do list.
Typical gas car
- Oil & filter change every 5,000–7,500 miles
- Spark plugs, ignition coils, fuel system service
- Timing belt/chain concerns on some engines
- Transmission fluid & filter service
- Exhaust system, catalytic converters, emissions sensors
Tesla (Model 3/Y as example)
- No engine oil or oil filter
- No spark plugs, fuel system, or exhaust
- Brake pads often last longer thanks to regen
- Still has: brake fluid, coolant, gearbox oil, cabin air filter
- Big-ticket item: long‑term battery health
Core Tesla maintenance items to budget for
1. Tires and alignment
Teslas are quick and heavy; they can eat through cheap tires. Rotate regularly and budget for quality replacements, especially if you’re buying a performance variant.
2. Brake fluid inspection
Even if pads last a long time, brake fluid absorbs moisture over the years. Have it tested and replaced on schedule, especially in humid or coastal regions.
3. Coolant system checks
The battery and power electronics rely on coolant. It’s not a frequent service item, but leaks, air in the system, or incorrect coolant types after repair work can be expensive if ignored.
4. Gearbox oil service (high mileage)
Not something most first owners see, but if you’re looking at a high‑mileage used Tesla, ask whether the drive unit gearbox oil has ever been changed by a qualified shop.
5. Cabin air filter & HVAC
Filters clog, blower motors age, and A/C refrigerant can leak. These are small jobs individually, but nice to have sorted when you take delivery of a used car.
EVs aren’t maintenance-free
It’s easy to swing from “oil changes are a pain” to “EVs never need anything.” That’s where people get burned on neglected used cars. The maintenance list is shorter, not nonexistent.
Used Teslas: fluids and wear items to check before you buy
If you’re shopping used, the question isn’t just “Does this Tesla use oil?” but “Has anyone cared about the fluids and consumables it does have?” A clean Carfax is nice; a car that’s been mechanically loved is better.
- Ask for service records showing any brake fluid and coolant work, especially on cars over 5–6 years old.
- Check for evidence of professional repairs after accidents, improper coolant refills or hacked drive unit work can cause headaches later.
- Pay attention to tire wear patterns. Uneven wear can hint at alignment issues or bent suspension from curbing or potholes.
- Have the HVAC system evaluated if there’s weak A/C or odd smells; a neglected cabin filter and A/C system can be a cheap fix, or a more expensive one if ignored.
Don’t forget the battery
Fluids are important, but for a used Tesla the battery pack and fast‑charging history are the main characters. That’s why a proper battery health report is worth far more than a stack of receipts for cabin filters.
