My friend accidentally pumped a half tank of 87 in my 2006 Chrysler 300c SRT8. I drove that gas down to a quarter tank then filled the rest of the tank with 93. I can that gas all the way down and now have a full tank of 93. It doesnt feel the same when i try to make a wide open throttle. Could be all in my head or could be true trying to figure out what to do, any suggestions?
