Do electric vehicles use motor oil?
- 8 years agoFavorite Answer
Pure battery electric vehicles like the Nissan Leaf or Tesla Roadster do not use motor oil at all.
Their electric motors run on sealed bearings which are sealed for life and are essentially maintenance-free.
"Hybrid" electric vehicles like the Chevvy Volt or Toyota Prius have internal-combustion engines which require pressurised lubrication and oil in the sump like conventional cars.
Note that transmission fluids or "oil" may be required by some electric vehicles, but this type of oil lasts a very long time because it is not contaminated by combustion products and hence does not require regular flushing and replacement.Source(s): I made my first battery electric car 32 years ago.

No motor oil, no air filters, no spark plugs, no tune-ups, no coolant (not in the motor - some EVs have battery cooling systems), in fact, no regular maintenance on the electric motor is needed at all.
Electric motors are extremely reliable and long-lived, and can even run for decades without maintenance. Think about the electric motor in your refrigerator, or your electric washer or drier. Those appliances do break, but it's almost never the motor itself that breaks.
Electric motors have just one moving part. Contrast this to a gasoline engine, which can have hundreds of moving parts. Now imagine putting a gasoline engine into your refrigerator - how crazy would that be? It wouldn't be nearly as reliable and trouble-free, would it?
This is one of the principal advantages of an electric car, and one of the reasons electric vehicles have historically held resale value, and lasted for many, many years. Electric motors just don't break.Source(s): * I'm an EV hobbyist.

Id assume no.
Even the smallest gas engines need motor oil. Lawnmower, leafblowers, weedwackers, and snowblowers all need oil. Either dedicated oil for lubrication or oil mixed into the fuel supply.
Are there any small electric motors that need oil? Like a blender, a cieling fan, the motor in a hairdryer. None of these need oil so a car electric motor shouldnt need lubrication. They would need a way to cool the motor so theyd probably have a coolant system, but i dont see a need for oil.
There might be some moving parts that need lubrication, but would probably be more a grease type application like a cv joint boot or a wheel bearing.

Sort of, motor oil is a lubricant and electric vehicles still move but it doesn't need the massive amounts of oil used by gasoline engines to lubricate the pistons as there are no pistons. Chances are the lubricants will be more like grease packed in the bearings then motor oil pumped to the bearings.

Electric vehicles that are not hybrids don't need motor oil because the electric motors are permanently lubricated. There may be some lubricant necessary for a transmission and rear axle where they are used.
It is a good question because we often concentrate on the emissions pollution produced by a petrol engine and forget about improperly disposed motor oil: 200 million gallons each year. http://www.epa.gov/wastes/conserve/materials/usedo... by comparison the Exxon Valdez oil spill was about 11 million gallons. This is almost 20 times that amount EACH YEAR: http://www.answers.com/topic/exxon-valdez-oil-spil...

Electric vehicles does not use motor oil.

Yes and no.
The motor itself does need lubrication of the bearings in the motor and drive components to function.
The electric motor itself has no need for sump oiling like an internal combustion engine does- so in that respect- no, they do not have a sump of oil for the motor itself.

Definitely not.electric engines is very efficient,reliable and stability on power transmission is fantastics.When comes to ROI its a type you need to consider
