Atlantic 4T 10W-30 is a 4-stroke motor oil for outboard engines. The product is based on premium base oils combined with special additives and features the following properties:

  • Lubrication of all engine parts
  • Very powerful detergency, which ensures the engine is cleaner
  • Good cold start properties
  • Very effective resistance to corrosion, oxidation and wear
  • Outstanding shear stability


Atlantic 4T 10W-30 is particularly suitable for use in high-speed, heavy-duty outboard motors. Because 4-stroke outboard motors place different requirements on motor oil, this oil is not suitable for use in cars. This oil complies with the latest requirements for outboard engines as set out by the NMMA.
