Biodiesel also is pretty destructive to the seals on the engine as it has higher levels of solvents the eat away at rubber. Renewable diesel is a better option, as it has higher cetane levels and can burn cleaner, and is designed as a drop in replacement for dino #2, though I don’t fully know how it’s sourced.

All I know is my truck ran like shit on B20 and not nearly as bad on R99. That, and the factory recommends reducing oil change and filter intervals by 50% on both bio and renewable. It’s a clusterfuck obscured by marketing.
