We have a local distributor who sells 100% bio.
I guess my question is... can we run 100% bio or must it be diluted with dino diesel?
I have run very close to 100% probably closer to 90% this past summer, I had no problems.
93 turbo is right that it will start to get to rubber at high concentrations, HOWEVER, it doesnt do it over night, I ran quite a few tanks of 90%+ through mine and havent noticed any rubber deterioration or weakening.
Like I said I dunno how long it takes to affect rubber but it is by no means instantaneous......it is long term. The rubber wont last forever regardless of what fuel you use.
