To me it’s frustrating that not all Illinois State Fair trams run on biodiesel. You’d think it would be wise to promote a fuel that can be made from waste products. It would also be good marketing in regards to other products that can be produced from crops. This also promotes an agenda of Made in America. Biodiesel is a fuel that burns cleaner and can improve the performance longevity of a diesel motor.
I’m not sure the biodiesel blend being used. The few places I’ve seen it available in our area only offer B20. The preference from an environmental standpoint would be B100.
