You are right IXLR8 the TDI is more stringent than my JD. I guess this whole Bio-diesel thing has me confused. My good friend was over last night and he operates a large dairy farm and he is feeling the pinch of fuel costs. My suggestion was to start cookin mash and make bio-diesel. He was unsure but willing to learn as I am. Mother Earth News is full of ads for cookers and articles to make but no cleanup talk (so much for tree huggers) so what to do???
I guess keep learning until a comfort level is reached. I do like the mix your own system no mess after you are done.
This is John Deere's official position on use of bio-diesel...
John Deere Power Systems has a strong commitment to the environment, energy security, and technological advances that have a positive impact on both.
Biodiesel certainly meets these criteria. While B5 blends are preferred, biodiesel concentrations up to 20 percent (
B20) blended in petroleum diesel fuel can be used in all John Deere engines certified up to Tier 3/Stage III A, as well as all non-emissions-certified engines, providing the biodiesel used in the fuel blend meets the standards set by the American Society of Testing Materials (ASTM) D6751.
We recognize the importance of biofuels to our customers and to the environment. Use of quality biodiesel in John Deere diesel engines has economic and environmental benefits, boosts development in rural areas, and helps provide energy security.
John Deere was one of the first off-highway engine manufacturers to factory-fill biodiesel in North America, and we approved B5 biodiesel in 2001. Since then, John Deere has continued to conduct biodiesel research and has performed lab and field tests using biodiesel fuel. We have also developed a fuel conditioner that is recommended when using lower biodiesel blends and required when using
B20 blends and above.
What does biodiesel mean for John Deere engines?
