I keep some around, for sure.
Use it just for maintenance purposes only, can not say for sure it ever fixed anything, but has not ever hurt anything, to be sure.
If I'm heading out on a several hundred mile ride, and have to gas up on the way out, I'll poor a little in the tank before I head out.
I can't say mine ever sits up for any length of time....maybe a knee surgery once, and a back surgery a couple of years back, but generally she gets out at least every 7-10 days for at least a 60+ mile run across town and back. That's the best maintenance one could ever do.
