I get best mileage from Shell or Sunoco, 1 top tier 1 not. Go figure

Shell Super Premium and Sunoco 260 were the only available pump 102 octane fuels I ever saw that met the early L88/ZL1 requirements for their incredible 12.5:1 compression.
As they both sell race fuels to meet certain requirements, I'd consider them both to be top tier. Sunoco is currently one of the largest suppliers of race fuel in the world.
