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.
Mobil Super 4T 20W-50 is a high-quality, heavy-duty mineral engine oil designed for high-performance 4-stroke motorcycle engines. It is specifically formulated to provide consistent protection for large-displacement engines, air-cooled twins, and motorcycles operating in extremely hot climates or under heavy load conditions.
The 20W-50 viscosity is the preferred choice for riders who need a “thicker” oil to ensure a stable lubricating film and reduced engine noise in high-temperature environments.
Key Features
-
Robust Mineral Formula: Crafted from highly refined base oils that provide reliable, year-round protection for daily commuting and long-distance touring.
-
High-Temperature Stability: The “50” weight rating ensures the oil stays thick enough to protect critical engine components even when the engine is running hot in heavy traffic or on long highway stretches.
-
Active Cleaning Agents: Formulated with additives that help prevent the buildup of carbon and sludge, ensuring the engine remains clean and maintains its efficiency over time.
-
Wear Protection: Provides a tough protective layer on gears, cams, and cylinder walls, significantly reducing metal-to-metal contact and extending engine life.
-
Smooth Wet-Clutch Operation: Fully compliant with friction standards required for motorcycles with integrated wet-clutch systems. It ensures predictable power engagement and prevents clutch slippage.
-
Mechanical Noise Reduction: The higher viscosity of this mineral oil is excellent at damping mechanical sounds, leading to a “smoother” and quieter engine feel, especially in older or air-cooled machines.

Why Choose Mobil Super 4T 20W-50?
-
Ideal for Cruisers & Classics: This oil is the gold standard for bikes like Royal Enfields (Classic/Bullet 350/500) and older air-cooled commuters that require a thicker oil for optimal sealing and cooling.
-
Tropical Climate Performance: In regions with high ambient temperatures, a 20W-50 oil provides a much better safety margin against oil “thinning” compared to 10W-30 or 10W-40 grades.
-
Proven Reliability: Mobil is a world leader in lubrication; the Super 4T line offers professional-grade protection at a price point that is accessible for everyday riders.
Maintenance Tip
Because mineral oils have a slightly shorter molecular lifespan than synthetics, it is best to stick to a consistent drain interval—typically every 2,000 to 3,000 km—to ensure the oil maintains its protective properties. Always check your oil level regularly, as air-cooled engines can naturally consume a small amount of oil during long, hot rides.
