Quicksilver 15W-40 Heavy Duty Diesel Marine Engine Oil

Quicksilver 15W-40 Heavy Duty is a premium oil for marine diesel engines, engineered to meet the stringent demands of modern high-load diesels. It satisfies the API CJ-4 service category, meaning it’s formulated to protect modern turbo-diesels with Diesel Particulate Filters (DPF) and SCR catalysts, while controlling soot and deposits to keep the engine clean and efficient.

Multi-viscosity SAE 15W-40 oil providing reliable lubrication across a wide temperature range – from cold start to full load operation.
Advanced additives protect exhaust after-treatment systems (DPF, SCR), extending their life and keeping emissions in check.
Excellent shear stability: the oil stays within its viscosity grade throughout the service interval, maintaining oil film thickness under heavy conditions.
Controls formation of sludge and varnish deposits, keeping the engine clean even during prolonged idling or high-temperature operation.
Meets Mercury MerCruiser specifications for inboard diesel engines, ensuring compliance with warranty requirements and giving owners peace of mind.

Marine diesel engines – especially modern ones equipped with emissions systems – require an oil that can withstand intensive operation and protect delicate components. Quicksilver 15W-40 Heavy Duty is formulated for exactly this purpose. It combines a robust base stock with a high-performance additive package that minimizes wear, fights soot, and keeps the engine internally clean. The result is an oil that not only extends engine life but also maintains its optimal performance, even when your boat is under daily use or heavy workload.

API CJ-4 Certification: This oil meets one of the newest and most demanding diesel oil standards. API CJ-4 means the oil is suitable for modern diesels (including common-rail engines) and is formulated with low sulphated ash, phosphorus, and sulfur content (Low SAPS). This protects particulate filters from clogging and ensures compatibility with stringent emissions standards (Euro V/VI equivalent) in marine diesel engines.
Built for Hard Work: Quicksilver 15W-40 Heavy Duty excels in applications where the engine runs for long periods under heavy load – for instance, hefty yachts, commercial fishing vessels, or tour boats. It protects the engine during long hours of high-load, high-RPM operation and even when using suboptimal fuel, by neutralizing acids from the combustion process.
Protects Emission Systems: Modern diesels rely on DPF filters and SCR (Selective Catalytic Reduction) systems to reduce pollution. The additives in this oil are designed to reduce soot formation and prevent it from accumulating quickly in the filters. Moreover, the oil’s low-ash characteristic means fewer leftover particulates that could clog a DPF or poison an SCR catalyst.
All-Season Reliability: 15W-40 indicates the oil is fluid enough at cold start to protect the engine on chilly mornings, yet viscous enough at operating temperature to maintain a stable oil film in hot conditions. This makes it suitable for a range of climates – from cold seasons to tropical heat.
Mercury Diesel Approved: Mercury Marine demands a high standard for their MerCruiser and Cummins marine diesel engines. Quicksilver 15W-40 Heavy Duty meets these requirements, which means by using it, you maintain your warranty compliance and give your engine the level of protection the manufacturer intended.
