Per the 2015 NHRA rulebook General Regulations, Section 20, 1:6 Fuel, pages 6 &7 (see below); Sunoco is the ONLY NHRA-accepted nitromethane supplier for both NHRA Mello Yello Drag Racing Series events and NHRA Lucas Oil Drag Racing Series events.
“Nitromethane: Only nitromethane from an NHRA-accepted on- site supplier may be present on-site or used on-site at any NHRA Mello Yello Drag Racing Series event (“NHRA National Event”) or NHRA Lucas Oil Drag Racing Series event (“NHRA Divisional Event”). To be eligible for competition, any team using nitromethane must use nitromethane from an accepted on-site supplier. At this time, the only accepted on-site supplier is Sunoco Racing Fuels. Fuel anywhere on-site at an NHRA National Event or NHRA Divisional Event, including without limitation, in the vehicle, transporter, pit area, or at the NHRA- accepted supplier’s on-site location, may be checked at any time and for any reason, including compliance with this rule and with the Nitromethane specification. Any participant who violates any rule regarding nitromethane may be banned from competition at the applicable event, and shall be subject to such other penalty deemed appropriate by NHRA.”
