Oil Changes: A Thing of the Past
With the absence of internal combustion engines, Teslas have made oil changes a non-issue. Unlike traditional ICE vehicles that rely on regular oil to lubricate moving parts and keep the engine health intact, Tesla’s electric powertrains operate without a drop of oil. This design not only eliminates oil-related maintenance requirements but also helps facilitate smoother operation by reducing friction in the engine. For owners, this means a routine-free ownership experience, which translates to saving time and money on maintenance.
Which Tesla Parts Need Oil?
Though EV owners often enjoy reduced maintenance needs, there are still a few components in all-electric Tesla vehicles that require lubrication. For instance, Tesla’s gearbox includes an oil filter that serves a different purpose than traditional motors. According to Munro & Associates’ teardown of Model Y, the gearbox relies on synthetic oil like Pentosin ATF 9 (part number 1095038-00-A) to keep moving and spinning parts in top shape, rather than oil used in a conventional engine. This transmission system even features a dipstick to check oil levels as CNET demonstrated with the Model 3. Unlike engine oil, this synthetic fluid doesn’t degrade from fumes or require frequent replacement. In fact, Tesla once recommended checking this gearbox oil during the 1st, 5th, and 9th years of ownership, but recent guidelines on the Support page no longer call for this.
What Fluids Does Tesla Use?
Even though Teslas are electric vehicles (EVs) that avoid gasoline or diesel, they still have some fluid requirements for smooth running and maintenance. Here’s a quick look at essential fluids for Tesla cars.
Brake Fluid
Like traditional fuel-powered cars, Tesla’s brake fluid operates in a closed hydraulic system. Yet, over time, moisture can sneak in through rubber hoses, seals, or fluid caps. This build-up of water could harm metal components and lower braking effectiveness. To ensure safety, Tesla owners should have the brake fluid checked every two years.
Transmission Fluid
Some Tesla models like Model S, X also 3 use transmission fluid in the gearbox to keep gears at the front and rear motors running smoothly. Tesla recommends a transmission fluid change every 12,500 miles.
Windshield Washer Fluid
While water might seem enough for cleaning windshields, windshield washer fluid is specially formulated for effectively keeping the windshield clear, especially in regions with zero temperatures where antifreeze properties are helpful. To refill, just open the hood, locate the reservoir on the maintenance panel, and fill it up.
Coolant
The coolant in Tesla vehicles serves multiple purposes like preventing battery cells from overheating. Using G48 coolant with ethylene glycol helps regulate temperature and prevents corrosion. Tesla recommends checking coolant levels periodically, as listed in the owner’s manual.
Grease
Tesla uses grease to keep certain components like handles, latches, hinges, and drive axle lubricated and functioning properly. This grease minimizes friction, extending the durability of these areas and making for a smoother driving experience.
