STA-BIL Fuel Stabilizer and Performance Improver

STA-BIL fuel stabilizer is designed to keep stored fuel fresh for 12 months. Stored fuel deteriorates in 60 days, causing varnish deposits to build up in engines. This buildup causes starting problems, poor performance, and reduced engine life. STA-BIL contains a water remover to prevent corrosion, a fuel injector and carb cleaner to restore power, plus it eliminates the need to drain fuel prior to storage.
