Joe,
I'm with IBLUBYU; I had never used Stabil until about 4 years ago. Now, I use it on everything; it's about the gummy residue that builds.
It's great for snow blowers, lawnmowers, etc., etc.
I put in the X-fire last year on a full tank and ran it a few times during the winter and the car was ready to go in the spring. Thanks for the post; I'm learning as well.
