Purpose and Specifications

MOTUL OUTBOARD TECH 4T 10W30 is a high-performance Technosynthese engine oil designed for 4-stroke gasoline outboard motors from brands like Mercury, Yamaha, Honda, Suzuki, and Tohatsu. This 1-liter bottle delivers smooth flow in cold starts down to -25°C and reliable protection up to 130°C operating temperatures, keeping your engine running strong in harsh marine conditions.

Key practical benefits include superior shear resistance for consistent performance during long idling or high-heat runs, outstanding anti-corrosion protection against saltwater intrusion even through the exhaust, and anti-foam properties that prevent air bubbles in the oil circuit. It also resists clogging to safeguard oil filters and maintains properties if contaminated by seawater, certified to strict NMMA FC-W standards for marine reliability.

When to Use / Replace?

Use this oil in outboard, sterndrive, or inboard marine 4-stroke gasoline engines requiring NMMA FC-W lubrication. Ideal for saltwater boating where corrosion risks are high. Replace according to your engine manufacturer's recommendations, typically every 100 hours of operation or annually, whichever comes first. Shelf life is 5 years when stored in a cool, dry place.
