How do I calculate the detergent concentration level to set for my liquid HE detergent?

Divide the package size in fluid ounces by the number of loads listed on the package, then match the result to the concentration chart: 1.5–2.49 oz/load = 2x, 0.9–1.49 = 3x, 0.7–0.89 = 4x, 0.5–0.69 = 5x, and 0.3–0.49 = 6x. If you do not get your desired cleaning results, try using a lower concentration number; if you have excess suds, try a higher concentration number.
