When is the best time to add Power Service diesel additives to my fuel?

The best time to add Power Service diesel additives is while you are filling up with fuel to ensure the quickest mixture of the additive to the fuel. However, the recirculation of fuel back to the engine means proper mixture will occur regardless of the time the product is added.
