The state of MN. did some testing , and with the recomened amount [ info on bottle ] the gell point perty much dublicated , b 20 added to winter mix , the normal 50 % #1 /50 % #2 with anti gell .
The only reason I do not use during winter is becouse of b100 is in a above ground tank , so too thick to put in truck tank to blend to b20 , in warm weather I blend 1/3 bio 2/3 #2 , at that point we seem to get the best performance , more that b33 , and seems to start to decline .
I wish I had acess to dyno for setting up the Cummins for the highest b blend that the eng. will perform with , playing with injector tips / holes , timing , ect.
