Why Gear Oil Matters More Than You Think
In Southeast Asia’s demanding operating conditions — from Myanmar’s mining trucks to Vietnam’s long-haul transport fleets — gearbox failure is one of the most expensive maintenance problems operators face. The root cause is almost always the same: inadequate lubrication under extreme pressure.
ECO MATIC Gear Oil EP-90 GL-4 is engineered specifically for manual transmissions, transfer cases, and non-hypoid gearboxes that operate under heavy loads and high temperatures. Its extreme-pressure (EP) additive package creates a protective film on gear surfaces at the exact moment metal-to-metal contact would otherwise occur.
Key Performance Benefits
Extreme pressure protection: GL-4 rated additives guard against scoring, pitting, and premature wear in spur, bevel, and helical gears — even under shock loading conditions common in construction and agricultural equipment.
Thermal stability: Maintains viscosity and film strength across the wide temperature swings typical of tropical and subtropical climates, from cold morning starts to sustained highway operation at 40°C+ ambient.
Corrosion and rust prevention: Protects yellow metals (brass synchronizers, copper alloys) while providing long-term rust inhibition for steel components — critical for vehicles operating in high-humidity environments.
Smooth shifting: Balanced friction characteristics ensure synchronizer compatibility and smooth gear engagement, reducing driver fatigue on long routes.
Recommended Applications
ECO MATIC EP-90 GL-4 is ideal for manual gearboxes in commercial trucks, pickup trucks, SUVs, agricultural machinery, and light industrial equipment. It is compatible with most OEM specifications requiring API GL-4 gear oil and is a direct replacement for any SAE 90 gear lubricant meeting this standard.
Available Packaging
1L bottles — ideal for single-vehicle top-ups, retail shelves, and workshop stock.
