Castrol Outboard 2T Mineral Boat Engine Oil

Castrol Outboard 2T is a modern lubricant for 2 stroke outboard boat / marine engines, it's been formulated with selected mineral base stocks & high performance additives to deliver maximum levels of protection in the most demanding conditions. It offers control over carbon deposits, protection from high speed wear and scuffing and ensures maximum protection against salt water corrosion.

This 2T Outboard boat / marine motor oil has been specially formulated to ensure prevention of ash build up in combustion chamber and piston crown, reducing the risk of pre-ignition. It maintains plugs cleanliness to allow ready and easy cold start and has excellent low temperature fuel miscibility.

Castrol Outboard 2T can be used in a wide range of outboard engines, with autolube system or premix, where NMMA TCWII or TCW3 oil is called for. It can be mixed with leaded and unleaded gasoline up to a 100:1 ratio, accordingly to manufacturer’s recommendation.

  • *Free shipping is available for UK Royal Mail, UPS Access Point™ (click & collect) and standard UK courier services (not express / priority / islands).
