Do EVs need an oil change?
No, electric vehicles (EVs) do not require oil changes because they do not have internal combustion engines (ICE) like petrol or diesel cars. Traditional oil is used in ICE vehicles to lubricate moving engine parts, reduce friction, and dissipate heat. Since EVs run on electric motors, they do not have an engine that requires oil for lubrication.
However, EVs may still need:
- Coolant replacement (for battery thermal management)
- Brake fluid change (similar to petrol/diesel cars)
- Gearbox lubricant (some EVs have reduction gears that may need lubrication, but this is rare and requires less frequent maintenance)
So, while EVs eliminate the need for regular oil changes, they still require some fluid maintenance for optimal performance.
Do electric cars cost less to maintain than petrol/diesel cars?
Yes, electric cars generally cost less to maintain than petrol or diesel cars. This is because EVs have fewer moving parts, eliminating the need for frequent oil changes, complex engine maintenance, and exhaust system repairs. Their regenerative braking system reduces brake wear, and electric motors require minimal servicing compared to internal combustion engines. Additionally, EVs have lower fuel costs since electricity is cheaper than petrol or diesel in many regions. While battery replacement can be expensive, advancements in battery technology are improving longevity. Overall, the reduced maintenance and operational costs make EVs more cost-effective in the long run. The only major cost of maintaining an EV involves its battery pack. Over time, batteries gradually lose their ability to hold a charge.
