Diesel engines easily run 400.000km especially Mercedes cars but petrol will give up way sooner

So there’s a a false assumption here that it’s not possible, or even LIKELY for well made gas (petrol) cars to make it to 400k+ miles. Properly serviced reliable vehicles will do this every damn time unless there is some form of mechanical failure that makes the mantenence not worth the price.

Every gas car I’ve ever owned has made it well past the 250k (402k KM) mile mark. I have a jeep in the yard at 260K miles (418k km). The engine’s still in great running shape, it’s the transmission that would cost more than the vehicle’s worth to repair.
