Sinova Marine CYN 50 BN 100 Achieves Prestigious WinGD OEM Validation

We are incredibly proud to announce that Sinova Marine CYN 50 BN 100 has successfully achieved Original Equipment Manufacturer (OEM) approval from Winterthur Gas & Diesel (WinGD). As of January 2026, our high-performance cylinder oil is officially included in the highly respected WinGD Validated Engine Oils - Version 18 directory.

This validation marks a significant achievement for our engineering and product development teams, underscoring our commitment to providing top-tier marine lubrication solutions to the global shipping industry.

What This Approval Means for Marine Operators

WinGD is one of the world's leading developers of two-stroke low-speed gas and diesel engines used in commercial shipping. Earning their OEM approval is a rigorous process that requires extensive field testing and proven reliability.

This certification guarantees to fleet managers, chief engineers, and vessel owners that Sinova Marine CYN 50 BN 100 fully meets WinGD's strict technical and operational requirements. It provides peace of mind that our lubricant will protect your engine investments even under the most punishing marine operating conditions.

Engineered for Superior Performance

Sinova Marine CYN 50 BN 100 has been meticulously developed using carefully selected, high-quality base oils combined with state-of-the-art additive technology. The Base Number 100 (BN 100) formulation is specifically designed to handle a wide range of fuel qualities, offering robust protection for modern two-stroke engines.

When utilizing CYN 50 BN 100, operators can expect superior performance across several critical metrics:

Exceptional Acid Neutralisation

Effectively neutralizes corrosive acids formed during the combustion process, particularly when operating on varying fuel qualities, drastically reducing the risk of cold corrosion.

Optimal Engine Cleanliness

Advanced deposit control prevents the buildup of harmful combustion residues, keeping piston ring grooves clear and minimizing the risk of ring sticking.

Uncompromising Wear Protection

Maintains a strong, stable hydrodynamic oil film to protect cylinder liners and piston rings from mechanical wear, even under high maximum continuous rating (MCR) loads.

Extended Service Intervals

By maintaining engine health and reducing component wear, the oil supports longer periods between overhauls, directly contributing to reduced operational downtime and lower maintenance costs.

A Key Milestone for Sinova Marine

The expansion of our approved product portfolio is central to our mission at Sinova Marine Lubricants. Achieving WinGD validation for CYN 50 BN 100 not only validates the technical superiority of our formulations but also strengthens our global position as a trusted, reliable supplier of marine engineering solutions.

As the maritime industry continues to evolve with changing fuel regulations and increasingly complex engine designs, Sinova Marine remains dedicated to staying ahead of the curve. We will continue to deliver engine-approved, high-performance lubricants that keep global trade moving safely and efficiently.
