Storm 5W-40 Full Synthetic Engine Oil

Power, Control and HIGH-Performance

Advanced power and protection for modern, turbocharged engines and demanding driving conditions. Formulated to premium API SN quality level.

Formulation Integrity

Storm’s full synthetic SN 5W-40 engine oil is built on the finest base stocks and the world’s most advanced additive technology, engineered to deliver maximum power, control and high performance in new-generation vehicles. With a high viscosity index — achieved through premium viscosity index improver additives — it provides remarkable stability across all seasons and operating conditions, keeping the engine at the highest level of efficiency.

Advanced Protection in Severe Conditions and Extended Driving

A defining characteristic of this engine oil is the exceptionally strong protective film it forms between moving components, preventing wear and abrasion even in long-distance driving and severe, high-load conditions. The advanced formulation withstands extreme engine heat and pressure, and by precisely controlling friction it significantly extends engine life while contributing to lower fuel consumption and minimized emissions.

Low Volatility and Thermal Stability

With exceptional resistance to evaporation, this oil remains in the engine considerably longer — meaning noticeably lower oil consumption and no need for constant top-ups. Its high thermal stability at extreme temperatures prevents oxidation and sludge formation in internal galleries: a critical property for the health of today’s sensitive, modern engines.

Active Detergency and Smart Lubrication

With this product, carbon deposits and contaminants get little chance to accumulate inside the engine. The formulation’s active detergent properties help keep components clean while guaranteeing fast, uniform and stable lubrication throughout the powertrain. This not only prevents power loss over time but also keeps sensitive components fully protected against harmful deposits.

Optimized Cold Starts and Protection for Modern Systems

This engine oil demonstrates an intelligent dual behavior: in severe winter cold it flows quickly and smoothly, guaranteeing a soft, friction-free start; in high summer temperatures it provides comprehensive protection for turbocharged, high-pressure engines. It is a complete answer to the technological requirements of vehicles equipped with Stop/Start systems and fuel-saving technologies — delivering confidence on every journey.

Frequently Asked Questions

How does 5W-40 differ from other grades such as 10W-40, and why is it better suited to turbocharged engines?

The first number (5W) indicates the oil’s fluidity at low temperatures: compared with 10W-40, this oil flows much faster in severe cold, protecting sensitive components at the moment of start-up. The second number (40) indicates the stability of the oil film at high engine temperatures. Because turbochargers operate at extremely high temperatures, the thermal stability of the 40 grade prevents excessive thinning and loss of the protective film under demanding driving conditions.

Does this engine oil genuinely reduce oil consumption?

Yes. It is produced from 100% full synthetic base stock with a very low volatility rating. In modern, high-pressure engines, low-quality oils evaporate quickly and oil volume drops. This formulation’s exceptional heat resistance minimizes evaporation, eliminating the need for constant top-ups.

Is this oil necessary for hybrid or Stop/Start vehicles?

Vehicles with Stop/Start systems and hybrids shut down and restart many times a day. This continuous cycle puts severe stress on the crankshaft and bearings, since for a few seconds at each start the engine runs without full oil pressure. Thanks to its advanced additives, this oil leaves a durable protective layer on components that persists even while the engine is off, preventing metal-to-metal friction and wear during repeated restarts.

What does the API SN quality level indicate?

API SN is one of the highest quality levels defined by the American Petroleum Institute for gasoline engines. Oils meeting this standard provide superior protection against high-temperature piston deposits, improved sludge control, and full compatibility with the alloys used in new-generation engines (designs up to 2020) — preserving catalyst and exhaust-system life.

What is the service life (drain interval) of this engine oil?

Thanks to its premium full synthetic base stock and high oxidation stability, this oil offers a considerably longer service life than semi-synthetic or mineral oils. The exact drain interval, however, depends on the vehicle manufacturer’s manual, driving conditions (urban traffic versus highway) and oil-filter quality — but as a standard, it maintains optimal, stable performance throughout its defined service period.
