Precision Engineered for Mid-to-Large Displacement Bikes
TERZO 4T 5W-40 is engineered for motorcycles with 300cc+ engines, combining full synthetic base oils with T-M OFA Technology to meet the rigorous demands of JASO MA2 certified oil. Key value propositions include:
1.1Wet Clutch Protection: Maintains friction coefficient within 0.12-0.15 (per JASO T904 standards), eliminating clutch slippage risks, with 33% lower wear rate observed in track testing.
1.2All-Climate Performance: 5W low-temperature fluidity (-30°C cranking viscosity ≤6,500cP) and 40-grade high-temperature stability (≥90% viscosity retention at 120°C) for -40°C to 150°C extremes.
1.3Extended Drain Intervals: III+ base oils and borated dispersants enable 8,000 km service cycles (2.5x longer than conventional mineral oils).

Titanium-Molybdenum Bipolar Molecular Layer: Ultimate Wet Clutch Protection
1 Nanoscale Adsorption & Friction Control
The JASO MA2 certified oil leverages nano-scale Titanium-Molybdenum bipolar molecules to form a 0.1μm directional adsorption layer:
Metal-to-Metal Contact Reduction: 33% lower clutch plate wear (SAE No.2 test rig data).
Dynamic Friction Stability: Friction coefficient variance ≤0.03 during rapid gear shifts, improving shift smoothness by 30%.
2 High-Temperature Shear Resistance
Advanced ester-based viscosity modifiers synergize with Titanium-Molybdenum molecules (key formula for high-temperature shear-resistant oil):
Maintains ≥95% HTHS viscosity retention at sustained 120°C oil temperatures, preventing camshaft wear from oil film breakdown.
Exceeds JASO MA2 micro-pitting resistance by 50% in FZG gear wear tests (Stage 12).
All-Climate Validation: From Arctic Cold to Desert Heat
1 Subzero Startup Protection (-30°C to -40°C)
Cold Pumpability: -30°C Brookfield viscosity ≤6,500cP (ASTM D5293), reducing cold-start wear by 25%.
-42°C Pour Point: Achieves 2-second Arctic cold starts (vs. 5 seconds for conventional 5W-40 oils).
2 High-Temperature Endurance (40°C to 150°C)
Thermal Stability: ≤3°C oil temp fluctuation and ≤5% viscosity loss during 3-hour high-RPM (10,000 RPM) endurance tests.
Oxidation Resistance: TBN depletion rate ≤0.15/1,000 km in ASTM D2896 accelerated oxidation trials.
Application Scenarios & Compatibility: Conquering Diverse Terrains
1 Recommended Motorcycles
Urban Commuting: Honda CB500X (28% lower clutch wear in stop-and-go traffic).
Long-Distance Touring: BMW F750GS (≤5% oil pressure variance across 8,000 km Tibetan Plateau testing).
