I use it mainly when I am about to store my car for 2 or more weeks. Right now I run it at least 2 days out of every week so I have not been using any. when the fuel dries out it usually becomes gummy and will cause the piston to not move freely in the sleeve therfore put after run oil in the motor. But on the other hand fuel has an oily base and does not dry out over night.
