The products are great. I have them set up to auto send every 6 weeks. My only suggestion. MAX MILEAGE is at 25 to one and FLASHPOINT is at 15 to 1, therefore I run out of the FLASHPOINT be for MAX MILEAGE. It would be better if FLASHPOINT was in a jug larger so that I use both jugs at the same rate. Only a idea, and may not be possible. Pitsburg Power has probably looked at this idea as well. They seam to be the leader in the industry.
