Usually I agree with you, but here no. I would not run a no detergent oil in any combustion engine. I don't think it has any add pack or anti-wear components. ND oil is for hinges, and maybe compressors.
In the pump maybe, but not the engine.

If the oil has detergents which I'm pretty sure it does, it should be fine to run in the pressure washer.
