You get worse gas mileage with the bio, using higher B rated fuel could void your power train warranty also. My F250 is rated for B20 but I was told using the B100 would void the warranty - it was not the dealer that said that though. You also have the issue of oil contamination and going through fuel filters faster. I'm gonna stick to dyno-diesel.
