Here is my dumb question of the week. Without modifying anything on the stock fuel system of a 2001 7.3 PSD, can I run B99? I am running B20 and can hear and see differences in my engine. B20 is $2.99/gal and B99 is $2.25/gal, and if I mix my tank 50/50 (if my math is correct) I have then created B60. Will the B99 and B20 mix in my tank or seperate? Thanks for the help.
