I agree to an extent.

If you have an A/F gauge, and the car wasnt tuned to the absolute brink of ignition timing... then you have a little margin to work with.

I constantly watch my A/F gauge so I will immediately notice if something goes wrong. I also dont have my ignition timing bumped to the very last degree of making power, so I know it has a couple degrees of wiggle room for less stable fuel.

So I suppose I would say that it depends on how "in-touch" you are with your tuning and monitoring it. If you are a set-it and forget-it guy and dont want to even think about it... than I agree just drain that tank and do a clean swap.
