[QUOTE=cookie88]It's my understanding that in the process of making bio, most of the glycerin (sp) is removed. If that's the case, why is the cloud point any higher than dino #2?

Scott, If the biodiesel meets ASTM specs than ALL of the glycerin is removed.
All vegy oils have different cloud points. Cannola is higher than soy, palm oil is lower yet. It is just the nature of ALL oils. We are presently using B-80 with no cold start problems. It was 13 deg here this morning and my cummins started just fine. FABMANDELUX
