Red LineŽ Diesel Fuel Catalyst. I use the gallon jugs and add two glugs direct from the jug per fill-up. It gets a little hard to get the last glugs out of the jugs. So I go ahead and start the new jug and then when there is room, I pour the last of the old jug into the new jug. I do it at the fueling station so I don't spill it at my place.
