@Glos_Guy, it’s not so much the mileage per year but per journey. If your 5,000 miles are on relatively longer trips where the engine gets good and warm and at speeds where you can blow through the filters, it’ll be good. However, for trips to the shop and back I’d expect all to have issues. If you can have a good blowout once a month on that mileage, you should be ok. If anything starts running rough, another I rev run should help. I was having a chat with our neighbour who’s a mechanic as I was saying an EV for continuously short runs was less problematic and he actually agreed as these filters were causing all sorts of trouble for a number of customers who do the shopping and doctors runs and little else.

I'll try to give my honest opinion but am always open to learning.
