Service Essentials for EVs vs Petrol Cars

 

As EVs gain popularity in Australia, there’s a noticeable shift in how vehicles are maintained. Combustion engine cars and EVs have distinct service needs, but understanding these differences is key as EVs continue to be integrated into Australian lifestyles. EVs are increasingly seen on Australian roads, moving from less than 1% of new car sales in 2020 to 8.5% in 2023, a figure that held steady at 8.4% in 2024. This steady growth shows a rising interest, though the market is still adapting to meet EV-specific needs.

While both types of vehicles require regular maintenance to stay in peak condition, comparing EV servicing with ICE vehicles reveals some unique requirements. EVs and internal combustion engine (ICE) cars have distinct service essentials due to differences in their technology and design. So, what exactly are the main differences?

Let’s dive into what you should consider for each type of vehicle to keep them running smoothly.

1. Fluids and Filters: Petrol/Diesel vs EVs

Traditional Cars - Petrol and diesel cars require regular oil changes to keep the engine running smoothly, plus transmission oils and coolant fluids. Don’t forget car filters—engine oil, fuel, and air filters all need checking and replacing over time. These essentials prevent contaminants from entering the engine, ensuring optimal performance.

EVs - Electric cars don’t have an internal combustion engine, so they skip the oil change. However, EVs still need coolant to manage battery temperature and, in some models, transmission fluids. Brake fluids are also crucial for EVs, as it ensures proper brake system operation. Additionally,  cabin air filters require occasional replacement to keep interior air fresh and clean.

2. Battery Maintenance

Traditional Cars - The 12-volt auto battery in petrol and diesel cars needs occasional testing and, when necessary, replacement. It powers everything from your lights to the car’s computer systems, so keeping it in top shape is crucial.

EVs - EVs feature high-voltage lithium-ion batteries in addition to the 12-volt battery. While EV batteries don’t need replacing as often, monitoring battery health is essential for maintaining range. Many EVs now include battery management systems to optimise lifespan, though service checks every few years can help you catch issues early.

3. Brake Systems: Regenerative Braking in EVs

Traditional Cars - Petrol and diesel cars rely on standard hydraulic braking systems, with regular checks on brake pads and rotors needed. Worn brakes reduce stopping power and can damage other components.

EVs - Electric vehicles typically come with regenerative braking, which uses the electric motor to slow down the car and recharge the battery. This reduces wear on brake pads, meaning they don’t need replacing as often. However, it’s still essential to check brake fluid and monitor pad wear to keep your EV safe.

4. Cooling and Heating Systems

Traditional Cars - Cooling systems in petrol and diesel cars prevent the engine from overheating and require regular coolant changes and inspections for leaks. Traditional cars also have a heating system that pulls excess heat from the engine.

EVs - EVs use electric systems for both heating and cooling, and since there’s no engine generating heat, they rely on battery-powered heating systems. Coolant remains necessary for the battery and motor, but without the extra engine heat, EVs might consume more power to regulate cabin temperature, which affects range in colder weather.

5. Frequent (And More Expensive) Tyre Maintenance for EVs

 

 

Traditional Cars - For traditional cars, tyre maintenance primarily includes regular tasks like pressure checks, tread depth monitoring, and occasional rotations. Traditional car tyres wear evenly under the lighter vehicle weight, making replacements less frequent and typically more affordable.

EVs - Tyres on EVs tend to wear out around 20% more quickly than on traditional cars due to the added weight from the battery. This extra load can also result in uneven tread wear, especially on tyre edges, requiring more frequent rotations and pressure checks to help balance the wear. EV tyres are built with reinforced sidewalls and low rolling resistance, making them around 50% more costly to replace. Regular maintenance specific to these needs can extend tyre life and keep your EV running smoothly.

6. Diagnostics and Software Updates

Traditional Cars - Petrol and diesel vehicles often need diagnostic checks to ensure engine and emissions systems are working correctly. However, unless you’re driving a high-end car, software updates aren’t as common.

EVs - Electric vehicles heavily rely on software to manage everything from battery health to navigation. Many manufacturers offer regular over-the-air software updates that enhance performance or add new features. It’s a good idea to keep up with these updates, as they can improve range and battery management.

7. Exhaust and Emissions

Traditional Cars - Petrol and diesel engines produce emissions, so keeping the exhaust system in good condition is essential. Components like the catalytic converter, muffler, and oxygen sensors require occasional checks to ensure compliance with emission standards.

EVs - EVs produce no tailpipe emissions, which means there’s no exhaust system to maintain, saving you both time and money in this area. This makes electric cars an attractive choice for those looking to reduce their carbon footprint and avoid extra servicing costs.

Comparing Costs of Maintaining ICE Cars vs EVs

Traditional cars with internal combustion engines (ICE) generally come with recurring costs like oil changes, engine repairs, and exhaust system maintenance, which EVs don't require. However, EVs bring their own unique costs. For example, their tyres, reinforced for extra weight and durability, can be up to 50% more expensive to replace. Additionally, EVs require battery health checks and, over time, potentially costly battery replacements.

While EVs often have fewer overall maintenance needs and lower costs for things like brake and fluid changes, they do incur higher costs in specific areas, like tyre replacements and battery care. 

In contrast, traditional cars have a broader range of routine maintenance needs, leading to more frequent but typically smaller expenses. Over time, EVs may offer slightly lower general maintenance costs but come with occasional higher-ticket items, whereas traditional cars spread their maintenance costs across more frequent but varied repairs.

Staying on Top of Maintenance with Superspares

No matter what type of vehicle you drive, keeping up with service essentials is crucial. For traditional cars, scheduling regular oil changes, brake checks, and fluid top-ups is key. EV drivers should focus on battery health, software updates, and brake system inspections. At Superspares, we offer a wide selection of service essentials not only for traditional vehicles but also for popular EV models, including parts for Tesla and BYD vehicles.
