STROKER OB40
A versatile, high performance engine oil, specially formulated for marine outboards requiring NMMA TCW3® grade oil. Stroker Marine OB40 is an alternative to the expensive brand names available in the market, without the compromise on quality. Stroker Marine OB40 is formulated (NMMA TCW3® grade) to protect against ring sticking and cylinder wall scuffing. OB40 will help minimise spark plug fouling, pre-ignition and exhaust deposits, whilst protecting the engine parts against rust and corrosion.
