ITs definitely best to add it in before you fill up... I woudlnt drive too long with such a high concentration, just kind of wasting it.....
By adding it to a near empty tank and then filling up you are having it mix real good... As jesda noted, its best to use it where the car will be running on the highway for at least 2-3hours straight. It will be good at any other time, but thats when ive noticed the best results.
