Petromin 4T 20W-50 is a heavy-duty, high-viscosity engine oil designed for four-stroke motorcycle engines operating under high temperatures and heavy loads. This “stay-in-grade” oil is particularly effective for large-displacement bikes and air-cooled engines that face the intense heat of stop-and-go city traffic or desert climates. It provides a thick, reliable cushion of protection that thinner oils might lose under extreme thermal stress.

Key Benefits

• Ultimate High-Heat Protection: The 20W-50 viscosity grade offers a thicker oil film, providing a superior barrier against metal-to-metal contact when the engine is running hot.

• Enhanced Oil Consumption Control: Perfect for older or high-mileage engines; its thicker composition helps seal piston rings and reduces oil consumption and leakage.

• JASO MA2 Certified Friction: Specifically balanced to ensure the highest friction performance for wet clutches, eliminating clutch slippage and ensuring precise gear engagement.

• Oxidation Resistance: Contains high-quality base oils and antioxidant additives that prevent the oil from thickening or turning into sludge, even after prolonged use.

• Corrosion & Rust Shield: Protects internal engine parts from moisture and combustion by-products during periods of storage or infrequent use.

Product Specifications

Petromin Super Ultra 7 is a high-performance, multi-grade engine oil manufactured using high-quality mineral base oils and advanced additive technology. Specifically designed for passenger cars and light commercial vehicles, this 20W-50 grade is ideal for engines operating under high temperatures and heavy-duty conditions. It provides a thick, protective film that excels in older engines or high-mileage vehicles where mechanical wear is a concern.

​Key Benefits

​Superior Thermal Stability: Maintains its thickness and lubricating properties even in extreme desert heat and high-stress driving.

​Engine Noise Dampening: The high viscosity helps reduce mechanical noise and vibration, providing a smoother and quieter engine operation.

​Oil Consumption Control: Effectively minimizes oil leakage and evaporation in older engines, reducing the need for frequent top-ups.

​Continuous Cleaning: Formulated with active detergents that prevent the buildup of sludge and carbon deposits, keeping the engine internals clean.

​Wear Protection: Provides a robust protective layer on moving parts to prevent metal-to-metal contact, extending the life of the engine.

​Seal Conditioning: Helps maintain the flexibility of engine gaskets and seals, preventing oil leaks common in aging vehicles.
