Put some gas in my car from a small mom & pop station yesterday. The gas was a lot cheaper than the name brand places. Now when I start my car, the idle fluctuates up and down and isn’t steady. Could the station be selling bad gas and could that be the issue? Will this hurt my car? Luckily I only put a few bucks in to get me home since I forgot my wallet. Just gonna go and fill up with gas from Mobil later today.

 

It can, never know what could be in it.

 

I'd use isopropanol, you could use something off the shelf at the auto parts store if you want . . . just look for something labeled to get rid of water in the gas. That would be a quick/easy cure if it's just water in their gas.
