Tesla has been a game-changer in the automotive industry with its electric vehicles (EVs). One of the most significant advantages of EVs is their fewer moving parts, which leads to less wear and tear and lower maintenance requirements. But does Tesla have an oil filter? This article aims to clarify this question and provide insights into Tesla’s oil filter system.
Does Tesla Have an Oil Filter?
Contrary to popular belief, Tesla vehicles do have an oil filter, but it’s not for the electric motor. The oil filter is designed for the gearbox or differential, which contains several moving components that require lubrication and cooling. A teardown of a Tesla Model Y by Munro & Associates revealed the presence of an oil filter, although it’s not located where the oil filter is usually found in internal combustion engine (ICE) vehicles.
What’s the Purpose of the Oil Filter in Tesla Vehicles?
The oil filter in Tesla vehicles is responsible for filtering metal shavings and other contaminants present in the transmission fluid. Although Tesla uses helical cut gears to minimize friction in the transmission, friction is not eliminated entirely. Hence, metal shavings can still appear under normal use, and the oil filter is designed to filter these particles and other contaminants.
Tesla Oil Filter Replacement Interval
According to a Tesla oil filter Reddit thread, the oil filter in Tesla vehicles should be replaced every 2 to 3 years or 20,000 to 30,000 miles. However, Tesla’s recommended Maintenance Service Interval Booklet does not mention filter or oil change intervals. Some experts recommend changing the transmission oil and filter every 20,000 to 30,000 miles or every 2 to 3 years.
Why Don’t Electric Vehicles Have Oil Filters for the Electric Motor?
Electric vehicles do not have internal combustion engines like conventional cars. Instead, they are powered solely by electricity, which eliminates the need for engine oil and oil filters. The electric motor does not have internal moving and reciprocating parts like pistons, piston rings, connecting rods, pushrods, valves, crankshafts, camshafts, etc. Hence, there is no need for engine oil or an oil filter.
Final Thoughts
Tesla vehicles do have an oil filter, but it’s not for the electric motor. Instead, it’s designed for the transmission or gearbox. The oil filter is responsible for filtering metal shavings and other contaminants present in the transmission fluid. While Tesla recommends changing the transmission oil and filters every 20,000 to 30,000 miles or every 2 to 3 years, the official Maintenance Service Interval Booklet does not mention filter or oil change intervals. As electric vehicles continue to gain popularity, it’s essential to understand their unique maintenance requirements and debunk any myths or misconceptions surrounding them.
