Chemical fuel additives don’t actually remove water from diesel the way mechanical systems do. They only manage water through two opposite methods: emulsifying it or separating it. 1. Emulsifiers / Dispersants (“Water Removers”) These break water into microscopic droplets and suspend them in the fuel. The water then passes through the system and is burned… Read more »
