"I met Rand Taylor, President of Fuel Ox at the 2016 New England Boat Show in Boston, MA. We talked extensively about today’s Ultra Low Sulfur Diesel and the additives available to boost horsepower, reduce soot, increase lubricity and reduce vibration. Fishing for Giant Bluefin Tuna with a harpoon requires a smooth running engine to allow you to get close to the fish. I use a lot of fuel over the course of a fishing season, sometimes Biodiesel (B20), other times off road Ultra Low Sulfur Diesel. I have been using Fuel Ox since the beginning of the fishing season and have just finished my second bottle. The engines in both boats are running great, with very little soot, no algae problems and a definite increase in performance and efficiency. Unlike other additives, you only need to add a small amount to treat a lot of fuel, so a bottle goes a long way. I am now using it in my tractor as well. I highly recommend it for any diesel application."
