I better count myself in as a "maker and user" of bio diesel. With the kind help of Fabman, I have produced 455 gal of beautiful bio diesel. I run 100% year round and my "trusty steed" loves it. Can't get over how clean the lube oil in the crankcase stays. I get all my waste oil from the same restaurant and have discontinued titrating. I just use Don's tried and proven recipe and end up with the same beautiful product. Don has patiently instructed me on how to reclaim my Methanol but I still have not been sucessful. That's fine. I produce great BD and the Methanol is gone from the finished product (don't know where the hell it goes). With the prices of #2 down to $2.45 I don't have the same enthusiasm as I once had but it is still great to keep from buying imported dino and keeping the air a little cleaner. Thankyou Don
