Glycerin content can indicate the quality of biodiesel and glycerin can be present as free glycerin or bound glycerin in the form of glycerides. Total glycerin is the sum of free glycerin and bound glycerin. A high content of free and total glycerin can lead to buildup in fuel tanks, clogged fuel systems, injector fouling and valve deposits.
