If I change my fuel from gasoline to E-85 will I need different protective clothing?
Answer:
In the 2016 NHRA Rulebook section 20, page 45 it reads. For unaltered full-bodied OEM vehicles with an unaltered fuel system using ethanol or methanol and unleaded gasoline fuel blends such as E-85 or gasohol the Protective Clothing requirements are the same as those for gasoline.
For any vehicle other than an unaltered full-bodied OEM vehicle with an unaltered fuel system using ethanol or methanol fuel blends in excess of 15% by volume such as E-85, requires the same protective clothing as is required for 100% alcohol and/or methanol fueled cars. For ethanol or methanol fuel blends of 15%or less the Protective Clothing requirements are the same as those for gasoline.
