Today's Ultra Low Sulfur Diesel (ULSD) and biodiesel are highly susceptible to microbial contamination, including bacteria and algae (“bugs”) that can clog fuel filters, corrode tanks, and damage engine components. Left untreated, contaminated fuel leads to hard starts, performance issues, and even engine failure when you need it most.
