Not having to deal with oil changes is one of the many benefits of driving an EV
I got service centers trying to rotate my tires every 3k miles because "ev". The oil change as well, oh you need to change oil every 5k because... because why?
You got brake fluid, calipers, but it’s not even close to a regular car.
The dealerships and shops are doing every one a huge disservice by lying about how frequently engine oil needs to be changed. It’s in the manual but even that should be on page one. And then they set reminders on the car inside whatever last changed or when near, miles. So they’ll set it for 5k instead of 6-8k as the manual says and reminder at when you hit 3k. Like cmon.
Or tell me that I need a balance every 3k miles in a Tesla. Shameless.
I can come up with one. What's your list?
Nope, glycol-based and synthetic. Not the best article, but best I could find at the moment:
EDIT: nope, that is definitely an electric motor on the top of that 2011 Leaf steering rack:
The other components just aren't as sensitive or exposed to as much abuse. Often, really only needing replacement if they’ve leaked out.
Haven't had to change or refill oil once.
Ymmv
Don’t get me wrong, my “fun” car (an old, beat up Jeep) is going on 2 years with the same oil (I barely drive it), but I known I need to change it soon.
Oil degrade with oxygen. Every time you drive that car, the oil are being re-oxygenated and continuing to degrade (along with being exposed to combustion byproducts).
Also, the type of wear you get often isn’t noticeable until it becomes catastrophic. In my case, a 30 year old car that’s already on its last legs “catastrophic” is more like “time to finally drag it to the scrap yard”.

There was suggested battery fluid maintenance when I first got the car every 3 years or so, but they removed that recommendation.
It's one of the reasons I just can't go back to a regular gas car.
Body, wheels, and suspension components all require maintenance. Just because those components have a less predictable maintenance schedule doesn't mean they don't crap out if problems aren't identified and taken care of. And unless you are driving a short range smart car, EVs weight more than most ICEs, which accelerates the wear and shortens the lifespan of many components.
Don't get me wrong, EVs should be more reliable than ICE still, but in my experiences motor and engine problems are rarely the death knell of a vehicle, body damage and rust are. There are always enough people crashing or junking their cars so that even less reliable motors can be easily had on the used market for cheap, if you don't just swap to something better to start with, but once you get significant body rust 95% of mechanics won't/can't deal with it and repairing metal body shell is a level of skill and tooling that most DIYs aren't going to even attempt.
Due to how online the whole platform is, it’s so much better than my older ICE car that has a cryptic wrench light on the dash.
Did I mention that the intervals are also so much cheaper? Tires are the one standout but pretty much every thing else is a dream
Nothing special for being a car, but an ICE and transmission weren't the only things on cars that move and wear.
Brakes need to be inspected but my last ICE vehicle went about 90k miles between needing pads. My EV has sealed drums in back (a choice VW made to reduce friction when brakes aren't in use and I think trying to slow corrosion of the components) and conventional large discs in front. If we have issues with the front brakes it will be due to corrosion as I don't expect to put enough wear on them to ever wear through the pads. In normal driving the brakes are only applied at full stops.
I don't expect EVs to have motor mounts like an ICE vehicle, as the motor is a few orders of magnitude smoother (commutation ripple vs cylinder firings) and shouldn't need fluid-filled rubber isolation mounts.
If I think of what I've had to replace on my cars over the years, half-shafts and CV joints and wheel bearings might now be the least reliable mechanical things on the car, plus the oddball failures, like a clock spring in the steering wheel or a window motor.
So I still have to keep tires inflated, rotated and balanced, keep good wipers installed, change the cabin air filter occasionally, and listen to the rest.
My source for my opinion is having done the vast majority of the maintenance and repair of our cars over roughly 4 decades and more than a million miles.
Even on an ICE vehicle, you have transmission oil and differential oil and lubricants in your air conditioning compressor and brake hydraulics and grease smeared on CV joints and door mechanisms and pretty much everything else that moves. But you still talk about "changing THE oil" and mean the oil-that-sees-combustion specifically (along with, typically, the filter that fights the constant battle of getting the worst combustion products out of it). I personally think that makes it fair to say "EVs don't require oil changes" because even though they don't magically eliminate the other lubrication systems or the need to maintain them, they do eliminate the one that is so much more obnoxious than the rest that we commonly called it "THE oil change" before this was ever a debate.
The only significant oil is for the reduction gearbox, but as it doesn't change gears the wear is very low. First change will pull out some metal I'd guess, quality of machining dependent. Every 60000km/2Y, 1-2 litres.
Batteries may be immersed in a high dielectric thermal fluid, which will experience some breakdown but over a long time period, more than 10Y.
Many EVs use hybrid water/oil cooling, typically water for the stator and oil mist/spray for the rotor and exposed parts of the windings.
Like, the price differential is so high that the high end artisinal lubricant market is dominated by chemically synthesized products that aren't strictly petroleum at all (though many of the reagents used to manufacture them probably come out of the petrochemical world).
Like yeah there's probably some box with gear oil might get a little nasty after 100-200k but gears are pretty hardy and don't demand all that much.
