Why would the new 6.7 TD be restricted to only 20% biodiesel? I don't understand why it (or any diesel) could not run 100% biodiesel?
let me add a nickle
i ran straight waste filtered peanut oil in my 06 6.0 with no issues, cept fuel filters
i then dropped to a more sensible ratio of 12 %, because vitamin B12 sounded better for the 6.0 than 5%
it tolerated it well and even when it was cold it still ran well
