New test for total glycerin has a new field test for total glycerin level in your fuel. The ASTM spec says glycerin contamination should not exceed 0.24%, so you can use this test to get a ball park idea of whether your fuel is in spec. The 3/27 or methanol test is an even simpler and cheaper way to see if your fuel is likely to be in spec, as it seems to fail when fuel tests higher than about 0.24%. You might use the new glycerin level test along with 3/27 to see how they compare. Since glycerin contamination is usually the culprit when folks have fuel filter plugging problems, testing for glycerin is probably the single most important quality test to do. But make sure your fuel doesn't have water in it either!
