Machines that operate at high rpm are in a category of their own, and a car is probably the only one most people ever own. There are metal parts inside separated by fractions of a mm, moving past each other at like 30-40 mph, back and forth like 100 times a second. It heavily depends on good lubricating oil to prevent heat from friction building up and wrecking the whole thing.
And the oil is a consumable, it degrades as it does its job, and needs replacing every now and again. It’s not part of the MOT inspection because it isn’t a risk to other road users, just damaging your expensive bit of kit (and wasting the environmental cost of the energy and materials that went into manufacturing it in the first place).
If a car breaks on the road it’s a danger to road users, this is just a fact. If it’s really that important it should be part of MOT. As simple as that.
If it’s not that important, then you should not get over people’s asses for that.
True, but breaking by not being able to speed up is less catastrophic than breaking by not being able to slow down, or not being able to turn.
Probably the most likely failure mode from old oil would be seizing up when the engine’s cold, so it just won’t start next time.
But you do you, I’m just saying they’re designed with oil changes in mind, and if you do that one basic bit of maintenance it’ll save you money in the long run…
It’s true clothes are not a good analogy.
