Marine engines operate in one of the most challenging environments for lubricants. Standard automotive or industrial oils are not designed to handle the combination of salt-laden air, moisture, high-load operation, fuel-related acidity, and seasonal inactivity.

One ocean. Two worlds. One standard of excellence.
Why Marine Lubrication Demands More
The marine environment does not forgive weak lubrication. Salt water, humidity, long operating hours, high-load engine conditions, corrosion risk, fuel quality differences, and extended time away from shore all place unique demands on marine engine oils.
Viksen Marine by Nordic is developed for both commercial vessels and leisure boats – not as a simplified version of one for the other, but as a complete marine range engineered for the specific demands of each application. Whether the engine room belongs to a cargo vessel, a workboat, a sailing yacht, or a high-performance motorboat, the principle is the same: the engine must remain protected at sea.
Acid Neutralisation
Marine diesel fuels can create acidic combustion by-products, especially in commercial applications. Marine engine oils require the correct alkaline reserve to help neutralise acids and protect cylinder liners, piston rings, and bearing surfaces.
Water Contamination Resistance
Condensation, spray ingress, and possible coolant contamination mean marine lubricants must maintain protective film strength even when water is present. Viksen Marine oils are designed to support reliable protection in moisture-prone environments.
Corrosion Protection
Salt air can affect every part of a marine engine room. Viksen Marine formulations help protect ferrous and non-ferrous metal surfaces during operation and during lay-up periods.
Sustained High-Load Stability
Commercial vessels may operate at high load for days or weeks, while leisure engines can run at high throttle during passages. Viksen Marine oils are developed to resist oxidation, maintain viscosity stability, and support long-lasting protection.
Environmental Compatibility
: Modern marine operations are increasingly shaped by emissions rules, low-sulphur fuels, and sensitive coastal or inland waterways. Viksen Marine includes formulations designed to support cleaner, compliant, and responsible marine operation.
The Viksen Marine Range – Built for Every Vessel
For Commercial Operators – Reliability Is Everything
In commercial shipping, the engine is the business. A vessel that cannot operate on schedule can create delays, additional costs, contractual pressure, and reputational damage. For commercial operators, lubricant choice is not just maintenance – it is part of operational reliability.
Viksen commercial marine oils are formulated for demanding vessel operations, supporting acid control, engine cleanliness, thermal stability, and long-term protection under sustained load.

For Leisure Boaters – Because Your Time on the Water Matters
For leisure boaters, the relationship with the water is personal. Weekend passages, family holidays, summer cruising, and coastal trips all depend on an engine that starts reliably, runs smoothly, and brings everyone home safely.
eisure marine engines face their own challenges: seasonal lay-up, infrequent use, cold starts after long inactivity, high-revving petrol outboards, diesel inboards, and the constant corrosion risk of salt water environments.

High TBN Reserve
Selected Viksen commercial grades are designed with the alkaline reserve required to help neutralise acidic combustion by-products and protect engine components during demanding marine operation.
Fuel & Emissions Compatibility
Viksen Marine includes formulations designed for different fuel types and operating environments, including low-sulphur fuels and vessels operating in regulated marine zones.
Thermal & Oxidative Stability
Commercial engines can operate continuously under heavy load. Viksen oils are developed to maintain viscosity stability, resist oxidation, and help reduce sludge and varnish formation.
Oil Condition Monitoring Support
For fleet operators, fluid analysis can support condition-based maintenance, optimise drain intervals, reduce unnecessary oil changes, and provide early warning of wear or contamination.
Lay-Up Protection
Advanced corrosion protection helps protect internal engine components during winter storage and long periods of inactivity.
Cold-Start Performance
Selected Viksen grades are designed to flow quickly at start-up, helping protect critical surfaces before the engine reaches operating temperature.
Outboard & Inboard Coverage
The Viksen leisure range includes formulations for four-stroke petrol engines, two-stroke outboards, diesel inboards, sterndrives, RIBs, motor cruisers, sailing yachts, and performance boats.
Full Synthetic Performance
Viksen Syn Sport is developed for high-output petrol engines, supercharged applications, and owners who want a higher level of protection for demanding leisure use.
One Standard Across the Range
What the commercial chief engineer and the leisure skipper have in common is simple: neither should have to wonder whether the oil in the engine is good enough.
Every grade in the Viksen Marine range is developed with the same seriousness: the right specification, the right protection, and the right performance for the environment it serves.
From commercial vessels crossing open seas to leisure boats exploring coastlines and inland waterways, Viksen Marine is built for engines that must perform when it matters.
From the Harbour to the High Seas
The Viksen Marine range exists for every vessel that depends on reliable engine protection at sea. From cargo vessels and workboats to motor cruisers, sailing yachts, tenders, and high-performance sport boats, Viksen is engineered for the realities of marine operation.
