Thanks Todd. I assume all other values the same as PS121?
i.e., Sulfur, copper stri corrosion, cloud point, carbon residue, carbon residue (Ramsbottom), Acid nœmber & Free glycerin. One question: I tested my carbon residue (closed cup) and it added up to 0,0711% (as opposed to 0,05 specified by ASTM). How critical is this, and where does this residue come from?
