Purpose and Specifications

Eurol Nautic Line 15W-40 SHX is a robust mineral engine oil engineered for marine diesel engines operating under heavy loads. This oil protects your engine by creating a stable lubricating film that works reliably from cold starts through high-temperature operation. The 15W-40 viscosity rating means it flows easily in cold conditions (winter rating of 15) while maintaining protective thickness at normal operating temperatures (summer rating of 40).

This oil meets multiple international standards including API CI-4/SL, ACEA E7, Volvo VDS-3, and Caterpillar ECF-1-A, making it suitable for heavy-duty diesel engines, gasoline engines, LPG engines, and light diesel engines—whether turbocharged or equipped with catalytic converters.

Key Benefits

• Superior Wear Protection: Strong additives minimize engine wear even under severe operating conditions, allowing you to safely reach prescribed oil change intervals
• Thermal Stability: Maintains protective film integrity at high temperatures without excessive thinning or breakdown
• Clean Engine Operation: Specially formulated to reduce deposits on piston crowns and ring grooves, keeping your engine cleaner longer
• Corrosion and Rust Prevention: Protects internal engine components from corrosion damage
• Cold Start Performance: Flows quickly at low temperatures to provide immediate lubrication protection

When to Use / Replace?

Use Eurol Nautic Line 15W-40 SHX in marine diesel and petrol engines requiring heavy-duty protection. This oil is ideal for commercial fishing vessels, cargo ships, and other marine applications where engines operate continuously under demanding conditions.

Oil Change Intervals: Follow your engine manufacturer's recommended service schedule. For heavy-duty marine diesel engines, typical intervals range from 250 to 500 operating hours, depending on engine load and operating conditions. Always consult your vessel's maintenance manual for specific guidance.

Operating Temperature Range: This oil performs reliably from -39°C (pour point) up to normal marine engine operating temperatures of 80-100°C, with flash point protection at 234°C.

Storage: Store in a cool, dry location away from direct sunlight. Mineral oil typically maintains quality for 3-5 years when stored properly in sealed containers.

Frequently Asked Questions

Q: Can I use this oil in my gasoline engine?
A: Yes. While optimized for diesel engines, Eurol Nautic Line 15W-40 SHX is approved for gasoline, LPG, and light diesel engines. It meets API SL gasoline specifications and works in turbocharged or catalytic converter-equipped engines.

Q: What does 15W-40 mean for my engine?
A: The '15W' indicates the oil flows easily in winter cold starts (thinner at low temperatures). The '40' means it maintains proper thickness at normal operating temperatures. This balance protects your engine during startup and under load.

Q: How often should I check my oil level?
A: Check oil level weekly during the boating season or before extended voyages. Top up if the level drops below the minimum mark on your dipstick. Low oil levels reduce protection and can cause engine damage.
