QT 93 is GREAT in new performance-driven street cars, old-school carbureted, and loaded-down family SUV.
Until a few years ago, 7-11 sold 93 octane CITGO gas from Venezuela. Man, that stuff was good juice! Exhaust stunk to high heavens, but I loved the e n d l e s s burnouts...Ah, the memories...
I'm told by some chemists in Houston that ordinary 93-octane flows through the pipes to local depots where individual companies "water it down" with modifiers, creating their versions of 93, 89, and 87. Locally, QT refines the 93 to make it better or gooder than "standard". Also, for you conspiracy theorists, this one-basic-gas-going-everywhere is how the government controls the Winter and Summer Federal fuel blends. I'll bet your car stuttered after a fill-up between April 30 and May 3, the Feds switched it over. Your car's computer adapted to it, and the Cobra 427 tour in central Texas got stranded when cars wouldn't run. Had to drain their tanks and get different gas from elsewhere...true story.
Anyway, cheap-ass Racetrack gas so screwed up the top end of my 289 hi-po ('67 Shelby) that I now give every Racetrack station "the finger" (not kidding).
