I've tried the red Sta-Bil Storage, and was unimpressed with its performance in my snowblower.
Right now I have a bottle of the blue Sta-Bil Marine and am testing it in the snowblower. But even the smallest bottle is relatively expensive, is more than I would use in 2 years, and I end up disposing of half the product.
I might also try the gold Sta-Bil 360 Performance, as it is available in a smaller bottle (4oz for $7) and appears to have the same attributes as the Marine version.
