I put $10 worth of 87 octane in my tank last month. After, it felt like the throttle was stuck or something. Also, it was starting up funny too. I put in a bottle of STP two weeks ago and premium gas. Now it's slowly driving better with every fill up of premium octane.

My question is how long should it take for a bad gas to go away?

it all depends on how low you let your tank get. if you let it go really low, you won't be mixing good gas with as much of that old crap. you might want to run some fuel injector cleaner with your next fillup too.
