UMA RACING FULL SYNTHETIC ENGINE OIL HP3000 10W-40 1L YAMAHA MT15 ADVANCED HEAT MANAGEMENT

UMA Racing HP3000 4T 10W-40 Full Synthetic Engine Oil (1L) is a professional-tier, race-derived lubricant engineered for high-revving, high-performance four-stroke liquid-cooled engines. Featuring Advanced Heat Management technology, the HP3000 formula is specifically optimized to maintain superior oil film strength and thermal stability under severe high-RPM operating conditions, making it an ideal performance oil choice for the Yamaha MT-15 series.

Formulated to comply with strict API SN and JASO MA2 regulatory specifications, this premium lubricant utilizes high-purity synthetic base oils that maximize engine efficiency, minimize power-robbing friction, and deliver exceptional component wear protection on both the street and the track.

Yamaha MT-15 Advanced Heat Management Profile

The Yamaha MT-15 is powered by a sophisticated 155cc, liquid-cooled, 4-valve engine featuring VVA (Variable Valve Actuation) technology. This engine loves to rev, frequently operating at sustained speeds above 7,000 RPM where the aggressive high-speed cam profile engages. At these high RPMs, immense frictional heat is generated inside the top end.

The UMA HP3000 addresses this with targeted protection:

• Thermal Shear Defense: Under the high-temperature and high-shear stresses of the MT-15’s high-compression cylinder chamber, conventional oils can thin out and fail. UMA’s Advanced Heat Management maintains a robust, continuous boundary layer over the piston skirts, wrist pins, and dual overhead surfaces, preventing metal-on-metal contact.

• VVA System Precision: The VVA mechanism relies on precise hydraulic oil pressure to switch smoothly between cam lobes. The excellent viscosity retention of this full synthetic oil ensures consistent oil pressure across all temperature ranges, keeping the VVA engagement crisp and seamless.

• JASO MA2 Wet Clutch Optimization: The MT-15 features an Assist & Slipper wet clutch system. The JASO MA2 specification guarantees the exact friction parameters required to prevent clutch slippage at high operating temperatures, ensuring maximum hookup during hard accelerations and rapid downshifts.

Key Features & Benefits

• 100% Fully Synthetic Formulation: Manufactured using high-purity synthetic base stocks that deliver superior oxidation resistance, extremely low oil consumption (volatility), and extended lubricant life compared to standard mineral or semi-synthetic oils.

• Shear-Stable Molecular Bond: Resists permanent viscosity breakdown caused by the constant mechanical slicing action of the MT-15’s tight-ratio 6-speed transmission gears.

• Advanced Detergent Chemistry: Actively fights carbon deposits, varnish, and ring-sticking sludge, keeping the engine interior clean to maintain peak compression, performance, and fuel economy.

• Fast Cold-Start Lubrication: The 10W rating ensures rapid oil circulation throughout the top-end valvetrain within milliseconds of a cold startup, minimizing initial startup wear.

Maintenance & Oil Change Guidelines for Yamaha MT-15

1. Crankcase Capacity Match: A standard oil change on a Yamaha MT-15 requires exactly 850 ml of engine oil (or 950 ml if replacing the oil filter). This 1.0 Liter bottle provides the perfect amount for a complete oil and filter service, leaving roughly 50 ml of leftover oil for eventual top-offs.

2. Filter Care: Always install a fresh OEM Yamaha oil filter along with your premium UMA synthetic oil change. Reusing a dirty filter introduces trapped metallic contaminants and old, degraded oil into the fresh synthetic mixture, reducing its efficiency.

3. Extended Service Intervals: Thanks to its high-purity full synthetic base and thermal defense system, this oil safely extends drain intervals up to 2,500 to 3,000 kilometers under normal street riding conditions—significantly outlasting conventional factory mineral lubricants.
