Any storage tank with water will have microbes (bacteria, molds, yeasts, fungus) multiplying in it constantly. One bacterium can multiply to over 250,000 in just 8 hours. The nasty sludge and slime formed from these microbes in the infected fuel will block filters and cause tank corrosion.
X-Tend industrial-grade fuel treatments stand the test of time for quality, effectiveness and value. X-Tend diesel conditioner and biocide treatment together will stabilize diesel, kill microbes that have formed and also provide anti-corrosion protection for storage tanks.
