STA-BIL Small Engine Pro (16oz/ 473ml)

Small Engine Pro Additive for Cleaner, Quieter Performance

STA-BIL Small Engine Pro is a high-performance additive engineered to clean, lubricate, and protect small petrol engines. Designed for dual-system use, this formula works in both oil and fuel systems to maintain peak engine condition. When used in oil, Small Engine Pro lubricates internal components, frees sticky valves and pistons, and reduces engine noise. In petrol, it dissolves harmful gum and varnish build-up to restore lost power and smooth out rough performance.

With added corrosion inhibitors, this additive provides robust protection against ethanol-related fuel system damage, extending engine life and improving reliability. STA-BIL Small Engine Pro is ideal for regular use in lawn mowers, generators, chainsaws, and other small engine equipment. Its advanced cleaning and lubricating action make it a valuable part of any maintenance routine. Safe for all petrol-powered small engines, one bottle treats up to 16 gallons of fuel or oil for ongoing preventative care.
