Had a discussion with my brother last week. Was telling him about bio-diesel. He said bio-diesel cannot be made from animal fat. I told him yes it could. Am I right or wrong?
With the new ULSD that is now being shipped, the Cetane is running very close to 40 and in some cases less than that. An aftermarket Cetane boost may be required. So any biodiesel such as B5 and up should be beneficial. Also the diesel fuel being shipped meets the new lubricity requirements, but these requirements are very minimal. So I recommend a lubricity additive. Again biodiesel would meet this requirement. B5 and up. (Most engineers claim B2 and up)quote:
A cetane number higher than required does not materially improve engine efficiency or operation. Most engine manufacturers recommend diesel fuels with a cetane number of at least 40. Diesel fuels sold by reputable marketers meet or exceed this requirement.
