FOR YOUR INFORMATION

I've driven this little leg a number of times and if you need to stop for gas, might I suggest exits 69 and/or 131 (south and north of Columbus, respetively). I'm pretty sure one is a Pilot station and the other a Flying J (haven't a clue which is at which exit) but they tend to have the cheapest gas around.

Now, this isn't entirely infallible but, generally, it does hold true.
