EV vs. Gas Maintenance: What You Actually Save
Electric cars skip oil changes, spark plugs, timing belts, and most brake jobs — so they cost meaningfully less to maintain than gas cars. Here is what disappears, what still needs servicing, and the real annual numbers from the models we track.

Do EVs cost less to maintain?
Yes — clearly. An electric car removes the most maintenance-heavy parts of a gas vehicle: the engine and the transmission. No oil to change, no spark plugs or filters tied to combustion, no timing belt, no exhaust, and no gearbox to service. Fewer moving parts means fewer things to wear out and fewer routine visits.
| Powertrain | Avg. maintenance / year | Models |
|---|---|---|
| Gas | $546 | 40 |
| Hybrid | $421 | 14 |
| Plug-in hybrid | $394 | 2 |
| Electric (EV) | $294 | 16 |
The pattern is consistent: gas cars average about $546 a year in scheduled maintenance, hybrids a bit less, and EVs the least at roughly $294 a year — about 46% lower than gas. These are scheduled-maintenance figures, not repairs — but the direction holds across the board because the EV simply has fewer systems that need periodic service.
What an EV skips entirely
The savings come from whole categories of service that no longer exist. These are the recurring gas-car costs an EV eliminates outright.
Gone on an EV
- Oil and filter changes — no engine oil at all
- Spark plugs, ignition coils, air filters
- Timing belts and serpentine belts
- Exhaust system, catalytic converter, emissions parts
- Multi-speed transmission service
- Most brake-pad replacements (regen does the braking)
Still needed on an EV
- Tires — worn faster from weight + instant torque
- Brake fluid and cabin air filter
- Battery coolant for the thermal system
- 12-volt accessory battery (eventually)
- Wipers, washer fluid, suspension wear items
- Software updates (often over-the-air, free)
The single biggest swing is braking. Because an EV slows itself with regenerative braking — using the motor to recover energy — the friction pads do a fraction of the work. Many EVs go past 100,000 miles on the original brakes, while a gas car often needs two or three brake jobs in that distance.
The catches: tires, repairs, and the battery
EVs are cheaper to maintain, but not free of costs. Three things offset some of the savings: faster tire wear, potentially pricier out-of-warranty repairs, and the battery — though the battery is a warranty question, not a maintenance one.
Tires. EVs are heavy and deliver instant torque, which chews through tires faster than a comparable gas car. Budget for tire replacement sooner — it is the one routine cost that can run higher on an EV.
Repairs. Scheduled maintenance is lower, but if something out of warranty fails, EV parts and specialized labor can be expensive, and not every shop services EVs yet. This matters most on older, out-of-warranty vehicles.
The battery. The pack is the expensive part, but it is covered by an 8-to-10-year, 100,000-mile-plus warranty and is not something you service on a schedule. Real-world data shows most batteries lose only a small fraction of capacity over many years. The realistic risk is an out-of-warranty failure on a high-mileage older EV — we cover how long batteries actually last in our EV battery life guide.
The bottom line on running costs
Lower maintenance is one of the EV's strongest cost advantages, and it stacks on top of cheaper home charging. Together they make EVs meaningfully cheaper to run day to day — though purchase price, insurance, and depreciation still decide the full ownership picture.
If you want the complete cost comparison, maintenance is just one input. See how charging stacks up against gas in our cost to charge an EV guide, the full head-to-head in EV vs. gas, and the lowest total-cost models on our cheapest cars to own ranking.
Frequently asked questions
- Do electric cars really cost less to maintain?
- Yes. An EV has no engine oil, spark plugs, timing belts, exhaust system, or multi-speed transmission — and its regenerative braking means the brake pads last far longer. Across the vehicles we track, EVs average roughly 40% lower scheduled maintenance cost than comparable gas cars. The savings are real and recurring, though they are partly offset by higher tire wear (EVs are heavy and torquey) and, eventually, costlier repairs if something out of warranty fails.
- Do EVs need oil changes?
- No. Electric motors do not use engine oil, so there are no oil changes — one of the most frequent and reliable maintenance costs of a gas car simply disappears. Some EVs have a reduction-gear lubricant that may be inspected over time, but there is no regular oil-and-filter service. That alone removes several visits and a few hundred dollars a year from the upkeep bill.
- What maintenance does an EV still need?
- Plenty is shared with any car: tires (EVs often wear them faster due to weight and instant torque), brake fluid, cabin air filter, wiper blades, windshield washer fluid, and 12-volt battery replacement. EV-specific items include coolant for the battery thermal system and periodic software updates. What disappears is the entire engine-and-transmission maintenance category — oil, plugs, belts, exhaust, and most brake-pad replacements.
- Is brake wear really lower on EVs?
- Yes, noticeably. EVs use regenerative braking — the motor slows the car and recovers energy — so the friction brakes do far less work. Many EV owners go well over 100,000 miles on the original pads, where a gas car might need brake jobs two or three times in that span. Lower brake wear is one of the biggest contributors to the EV maintenance savings.
- What about the battery — is that a hidden maintenance cost?
- The battery is the one big-ticket worry, but it is not a routine maintenance item. EV batteries are covered by an 8-to-10-year, 100,000-mile-plus federal warranty, and real-world data shows most lose only a small fraction of capacity over many years. You do not "service" the battery on a schedule. The realistic risk is an out-of-warranty failure on an older EV, which is why we cover battery longevity in detail in our how-long-do-EV-batteries-last guide.
