I added sta-bil to a 2011 honda accord I don’t drive much. I didn’t use a funnel. Is there anything stopping it from going into the gas tank like an anti-siphon valve?
likely it will make its way down to the tank, but you can simply get to the nearest gas station and add 1/2 a gallon to get it out of your worry list?
No, there is nothing to stop it from making its way into the gas tank.
In order to properly distribute the Sta-bil, you’ll want to run the car for some period of time to get the treated gas all the way up to the injectors…

… like getting to the gas station to add gas to the top as you put it in storage…
