Turning back the clock half a decade... would oil bath air filters have ANY usability in the modern world on a modern vehicle, despite the maintenance hassle? I've been reading up on them a bit later just out of curiosity, with my understanding being that they didn't necessarily filter small particulates as well as modern paper filters, but have potentially even better efficiency for larger particles. (how much different particle sizes affect wear i'm not sure) My understanding is they are still used on certain farm tractors and industrial equipment especially in very dusty conditions. Yet can sometimes need DAILY servicing in those conditions. Though i'm wondering if paper filters would last even shorter under those conditions - ie will oil bath filters actually last LONGER between service intervals, despite the ease of a 30 second air filter swap being far more convenient?
