Purpose and Specifications

ALCO FILTER Transmission Oil SAE 75W-90 GL4/GL5 1L delivers smooth gear shifts and long-lasting protection for manual transmissions, differentials, and transfer cases in cars and light trucks. This versatile oil meets tough standards like API GL4, API GL5, MB 235.6, and ZF TE-ML 02B/05A/07A/08/16B, making it ideal for European vehicles from Mercedes-Benz, ZF-equipped models, and more.

It flows easily in cold starts down to -40°C for quick protection and stays thick up to 150°C under heavy loads, towing, or high-speed driving. Expect gear life extension with minimal wear, easy synchronizer engagement for precise shifting, and resistance to breakdown for fewer maintenance stops.

When to Use / Replace?

• Use it in: Manual gearboxes, hypoid axles, and final drives needing GL4 or GL5 protection, especially ZF and Mercedes systems.
• Replace every: 60,000-100,000 km or 3-5 years under normal driving; check sooner for towing, off-road, or severe conditions.
• Shelf life: Up to 5 years unopened in cool, dry storage.

Practical perks include quieter operation, better fuel efficiency from reduced friction, and compatibility with seals to prevent leaks.
