Red Line Two-Stroke Racing Oil is a high-temperature-stable synthetic two-stroke oil that prevents deposits on combustion chambers, exhaust ports, upper ring and piston crown. Dyno-proven for 3-5% gains over longer runs, it suits racing and daily two-stroke use — motorcycles, marine, snowmobile racing and more. Mix at 50:1 (useful up to 100:1 by conditions) and pre-mix with gas or up to 50% alcohol. Identical chemistry to Red Line Two-Cycle Kart Oil. Case of twelve 16-oz bottles.
