As I stated in the prior post of mine, SeaFoam is what you want to use, not just solely a fuel stabilizer. I've had issues with products like Sta-Bil (it is cheaper though.)
Today we'll be putting our car into storage. Full tank of gas with SeaFoam, pull the battery cable, and leave for six months. Been doing that for over 20 years with various cars/trucks (both fuel injection and carb'ed.) Only way to go, and like I stated earlier in the spring they start right up and the SeaFoam cleans the injectors for better MPG giving you a payback even.
On Edit:
I always figure this goes without saying, but if you do treat the gas you have to insure it makes it up to the injectors or carb. Which means after you put Seafoam in, drive the vehicle for a few miles. You can't just park the car and put SeaFoam in it and expect good results.
