UMA RACING PERFORMANCE OIL
UMA Engine Oil Collection
High-performance synthetic engine oils engineered for smoother riding,
maximum engine protection, improved throttle response, and longer engine life.
Liqui Moly 4T Street 10W-40 is a high-performance semi-synthetic engine oil developed for air-cooled and water-cooled 4-stroke motorcycle engines. By blending synthetic technology with high-quality mineral base oils, it offers a “best of both worlds” solution: the superior protection and thermal stability of synthetics with the reliable lubrication and noise damping of mineral oils.
This 10W-40 viscosity is the most versatile “universal” grade, making it the perfect choice for a wide range of motorcycles, from 150cc commuters to high-performance 600cc+ machines.
Key Features
Synthetic Technology Blend: Engineered to provide significantly better shear stability and engine protection than conventional mineral oils, especially under high-heat conditions.
Optimal Wet Clutch Performance: Specifically tested and certified for wet clutch systems. It prevents clutch slippage and provides a smooth, consistent feel during gear transitions.
High Thermal Stability: Maintains a strong lubricating film even during long-distance touring or heavy stop-and-go city traffic, preventing engine “thinning” and power loss.
Advanced Engine Cleanliness: Formulated with powerful detergents that actively prevent the formation of carbon deposits and sludge, ensuring the valves and pistons remain clean.
Low Evaporation Loss: Reduces oil consumption over long service intervals, meaning you won’t have to top up your oil as frequently.
Quick Cold Start Protection: The 10W-40 rating ensures the oil flows quickly to the cylinder head during startup, minimizing wear when the engine is most vulnerable.

Why Choose Liqui Moly 4T Street 10W-40?
The “Goldilocks” Viscosity: 10W-40 is the most widely recommended grade by manufacturers like Yamaha, Suzuki, Kawasaki, and Royal Enfield (for older models), offering perfect protection in both summer and winter.
Smooth Gearbox Feel: Liqui Moly’s additive package is famous for transforming “clunky” gearboxes into smooth-shifting units, making the bike much more pleasant to ride.
Engine Longevity: By reducing friction and maintaining cleanliness, this oil helps extend the life of your engine, keeping it running like new for thousands of kilometers.
Maintenance Tip
For optimum performance and engine protection, always use the oil unmixed. While semi-synthetic oils are durable, it is recommended to change the oil every 3,500 to 5,000 km (or as per your manufacturer’s manual) to ensure the additives remain effective. Always replace your oil filter at every oil change.
