Pls inform me how long does a unopened bottle of 360 Protection last before it's considered bad or ineffective. Secondly, once opened how long does the same bottle last or effective.

Bought Stabil360 about 6 months ago. Using it in car and my 1981 F -250. Just put some Stabil360 in my 2009 Piaggio scooter. It cured my problem and the scooter is back on the road again. Great stuff! Thanks!

Gold Eagle is a local company in Chicago, and they've been great to the enthusiast community here, so I always look for their products first. I bought a 60-year-old Mopar two months ago, which had not seen frequent use for about 20 years. It was always a hard first start; the previous owner said that's "just the way it is". After replacing the (leaking) fuel tank, I wanted to protect my hard work. Within a day of my first fill-up using 360, and no other adjustments, my antique starts as easily as a brand new car, every time, and the exhaust smells much cleaner, too!

I've been using this in a 10 yr old Hundai, Definitely have noticed improvement in performance.
