STA-BIL In-Season Protection (formerly 360 Protection — same bottle, new name)

This isn't a one-trick ethanol treatment. It's a full fuel system protector — cleaning, corrosion protection, and stabilization in one bottle, built for whatever you're driving or running right now, not for storage.

The label backs it up: Premium P.E.A. as the cleaning agent — the same class of chemistry the top-tier fuel system cleaners use to strip gum, carbon, and varnish out of injectors and intake valves. Add corrosion protection against ethanol-blended fuel and a 12-month antioxidant stabilizer package, and you've got cleaning, protection, and stabilization happening in one pour.

How to use: Add at every fill-up — the 10 oz bottle treats up to 50 gallons. No measuring beyond that, no waiting period, just pour it in before or after you fuel up.

Who needs this: Anyone running a daily driver, boat, or small engine on pump gas. If it's in regular use and not in long-term storage, this belongs in the routine.
