Although they may use oils as lubricants, most electric vehicles (EVs) don’t use oil in a way that necessitates standard engine maintenance.
Hybrid EVs need routine oil changes since their engines need to be lubricated even when they only utilise a little quantity of gasoline. Depending on the kind of electric car you’re driving, the answer to the question “Do EVs utilise oil?” can become a little complicated.
Do Electric Cars Need Oil Changes and Other Maintenance Procedures?
Depending on the type of EV, some do and some don’t. There are several types of electric cars, and each uses oil in a unique way.
Battery electric vehicles (BEV): Since they don’t have internal combustion engines, these pure electric vehicles don’t require oil changes.
Hybrid electric vehicles (HEV): These vehicles have both electric and tiny internal combustion engines, thus they do require oil changes. Oil changes might be necessary less regularly than with ICE (internal combustion engine) automobiles, though.
Electric vehicles can still gain from routine maintenance and inspections because they share many of the same systems as ICE vehicles. A suggested maintenance schedule will normally be given by the manufacturer.
For instance, BEVs have battery coolant but not engine coolant. This coolant still needs to be checked and filled off if it ever gets low even if it doesn’t leak or breakdown as frequently as engine coolant does. For that, the manufacturer will have a suggested schedule.
Some BEVs have oil in their gearbox, e-axle, and transmission. This transmission fluid needs to be checked and replaced at the manufacturer’s recommended interval because it deteriorates with time.
How Do EVs Use Oil?
Transmission: Some BEVs have oil in their gearbox, e-axle, and transmission. This transmission fluid needs to be checked and replaced at the manufacturer’s recommended interval because it deteriorates with time.
When performing routine maintenance inspections, service personnel frequently check for leaks and fluid conditions even when the owners’ manual doesn’t specify an interval.
Other components: From a maintenance standpoint, you shouldn’t worry about how oil is used by electric automobiles. Both wheel bearings and electric motor bearings utilise oil, but neither one needs to be maintained on a regular basis.
Some other electric motors, such as the ones that lock your doors, might have parts that are petroleum-based, and some other systems, such as air conditioning systems, utilise oil for lubrication.
