WESTELL. what part of houston do you live in? i use to live in Pasa(STINKY)dena. God, i hate that town. you gas up at Stop-N-Rob?[/QUOTE]
Got my business near IAH airport. Live near Tomball / Spring.
Stop-n-Rob - only if I had to. It'll run, just not as good on 89, won't hurt the motor, computer'll compensate.
Adearmas - a lot of race / performance shops got the juice, and you can always buy it at the track, but they charge more, typically.
like i wrote above, mix 1/3 or 1/4 UNLEADED race gas and you got a goat on steroids

sometimes, it'll throw engine code, but goes away during next "pure" tankfull of "tank" gasoline.
