Why is it necessary to change vehicle oil regularly, and not just change the filter and add new oil as needed?
In: Engineering
Because we use low quality oil filters and don’t really filter all the oil just the stuff going to the pump. It’s easy and pretty cheap to just dump the oil and put fresh in.
On larger equipment you can. Have bypass filters. This allows more oil to be pumped through a second filter cleaning it. Just changing the filters you can run many miles.

I believe amsoil has ran a semi a million miles on the same oil just changing filters , but I can’t remember the exact mileage.
