Keep your 2 stroke marine out board running efficiently and maintain reliability with Penrite Outboard 2 Stroke Oil. This semi synthetic, low smoke 2 stroke oil is specially designed for use in water-cooled marine outboard engines that require the use of NMMA TC-W3 specification oils. The ashless additive formula helps to minimise combustion deposits that can cause spark plug fouling, piston ring sticking and exhaust port blockages. Penrite Marine Outboard 2 Stroke Oil is fully licensed for use where NMMA TC-W3 is required. Suitable for use in all premix and oil injection systems. To find the correct 2 stroke oil type and weight suggested for your vessel; either check with your manufacturer, your local mechanic or head in-store and talk to one of our friendly team.
