You may not know that we categorize the contamination level of your fuel in four stages. Stage 4 is the most contaminated, at 80-100% contamination. Stage 3 is next with 60-79% contamination. Stage 2 has 40-59% fuel contamination. Reaching Stage 1 is our goal, which means you have zero (0) to nearly zero contamination.
