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.
