Not Ranked
I would agree with the guys about mixing with a racing full. Most 110 octane will be a leaded product. The Chevron Traq Tech III would be the best. Lowest price at $430 a 55 gallon barrel in Texas. Chevron still mixes and tests their own product and I don't believe they add color. VP is about $445 a barrel (which I race with), but they buy the petroleum products elsewhere and mix themselves. Only issue is the purple dye they mix in can get messy/goopy if you don't run often. Then Sonoco 110 ($450) is good and mixes well with 91 pump gas for racing (Denver) and not much dye, if any. We blend 50/50 when racing at high altitude, and it cleans the crap out of everything.
I know little about the unleaded fuels from the 3 producers, but know guys who add and mix in their race cars.
