Purpose and Specifications

Comma EP80W90 GL4 1L is a tough mineral gear oil built for manual gearboxes and differentials. It handles extreme pressure from gear meshing, keeping shifts smooth and parts protected in hypoid, spiral bevel, and double reduction rear axles.

This oil meets key specs like API GL-4, API GL-5, Ford SQM-2C 9008-A (also Ford M2C197-A), and MB 235.1 (also MB 235.0). The 80W-90 viscosity flows easily down to -30°C for cold starts and stays thick up to high operating temps around 100°C+, slashing wear and noise.

• Smooth, quiet shifting: Reduces gear grind and vibration for everyday driving.
• Long gear life: EP additives shield against metal-on-metal contact under heavy loads.
• 1L bottle: Perfect for most manual transmission fills or top-ups.

When to Use / Replace?

Use this oil in older vehicles or classics calling for 80W-90 GL-4/GL-5 specs, especially Ford and Mercedes models. Ideal for manual transmissions in daily drivers, trucks, or off-road use where gears see high stress.

Replace every 50,000-80,000 km or 3-4 years under normal conditions; cut to 30,000 km or 2 years for towing, heavy loads, or severe duty. Check fluid level monthly and swap if it darkens or smells burnt. Shelf life is 5 years from manufacture date (check bottle code YYYY.MM.DD).

Pro Tip: Drain old oil completely, refill to spec, and test drive to confirm smooth operation.
