2011 Buick Lacrosse with engine code P0013

Question

So I took my 2011 Buick Lacrosse to Colorado it is only a 4 cylinder so it seems to be a little rough on the car. Also the gas out there was 85 (lower grade the MN) So should I get an oil change and run through a tank of gas first to see if the light turns off or does this have nothing to do with the P0013 error code ?

Thank you for your help
