I've used nothing but red Sta-bil since E-10 hit the streets around here. I don't use anything in the cars/trucks as we drive lots of miles per month in both.
My 2001 5500-8500 surge gen set has had nothing but E-10 and red Sta-bil. In the winter months I keep four 5 gal gas cans full and ready with Sta-bil. However non of my gas sets over maybe 3-4 months in the winter season.
I also have a 2011 60" zero turn and a 1992 Cub Cadet mowers that mow about 5 acres per week in warm season. During winter months their not used and set with nothing but Sta-bil and E-10 or reg gazz if I think about it.
Same with my pressure washer....two chainsaws....string trimmer.
