How often do I need to take a DPF-equipped diesel for a long run?
We are looking to buy a diesel estate but have had conflicting advice on how often you have to take them out for longer, faster drives to avoid problems with DPFs. Is it twice a month or every couple of months? We do over 15,000 miles per year but that is made up of usual short trips along with a very long trip, over 1000 miles, every few months. Is this enough?
Repeated short runs from cold could block the DPF because it will be unable to regenerate (burn off) the soot from the repeated cold starts. For every three short runs from cold you need a run of at least 20 miles.
