How do I use Redex DPF Cleaner?

Add one bottle of DPF cleaner to a full tank of fuel. This product is not consumed at the injectors, so one bottle is required regardless of tank size.

If the DPF light is on, once the DPF cleaner has been added drive for 30-40 minutes down the motorway at a constant speed of 60 plus mph. This is required for the DPF to clean itself. The Redex DPF cleaner lowers the temperature at which the soot burns from the DPF.
