Thank you for your interest in Berryman. While Berryman B-12 Chemtool Fuel Injector Cleaner (part #0116) is great for cleaning fuel injectors, carburetors, and intake valves, it does not act as a fuel stabilizer.

If you want a product that does all of those things, we recommend Total Engine Tune-Up (part #0316). This is a combination gas-diesel product that cleans carburetors, all types of injectors, and intake valves (in non-GDI engines); cleans disperses sludge in the crankcase; disperses moisture in fuel and oil; restores lubricity for longer equipment life and better fuel economy; and stabilizes both gas and diesel fuels.
