FWIW I've ran a few partial (1/2-3/4) tanks of B20 in my 12 CTD. Never had any issues. That was a couple years ago. IMO I don't see how filling a partially empty tank with some B20 would make a difference. I won't run it 100% of the time even with the CAT dual filter setup I have.
What I'm having a hard time wrapping my head around is what exactly does Cummins think will happen if I do run B20 100% of the time. Is it an injector, HPFP, etc problem? If I were deleted then it certainly wouldn't be an EGR-DPF problem.
I've even asked the local Ram service guy and he didn't have an answer either. Seems that no one knows for sure.

You can run it with good filtration. 13 and newer has better filtration the 07.5-12 models. That is all. Put filter kit and your good.

Not even close.

Bio is VERY hard on oil. Ever seen the oil change schedule when Bio is used? Check it out.

Bio is also very hydroscopic. If some companies put some magic juice in there Bio, water will go right through even the best of filters.
Have any idea on what water can do to a HPFP or a set of injectors?

Years ago a diesel mechanic friend of mine went to a Bio company that had three of their delivery trucks that would not run. He pulled the injectors and found snot all of the tips of them. He had to clean and replace some of the parts in the fuel system to get them running again.

Run it if you want. I will never run anymore than 5%. I pulled into several stations up in Oregon last week. I left when I found out their diesel was over 5% Bio.
