Chevron/Techron product in the black plastic pour bottle, available @ Costco's nationwide.
Been pouring one into the gas tank every oil change for the past ten years. Our fleet luvs the stuff.
No pings, no misses, no tank condensation (no gas line freeze ups) .
If your coming from trouble?
I'd try one each fill up until the "problem" quits? If you buy @ Costco that would be a six pack, I think? Used to be a four pack?
If the Costco pack doesn't clear the problem, check the throttle body and professional cleaning, would be my next step.
