Purpose and Specifications

RAVENOL EPX SAE 90 GL-5 is a mineral-based transmission oil designed for manual transmissions, axle drives, and differential gearboxes in cars and work machines. This single-grade oil works year-round in both winter and summer conditions, eliminating the need for seasonal oil changes.

The oil meets strict industry standards including API GL-5, MIL-L-2105 D, and approvals from major manufacturers like Mercedes-Benz (MB 235.0), ZF, MAN, and Ford. These certifications ensure it handles extreme pressure situations in hypoid gears—the type found in most vehicle differentials.

Key Benefits

• All-season protection: Flows smoothly in cold winter conditions while maintaining a protective film at high operating temperatures (up to 90°C in normal driving)
• Quieter transmission: Reduces gear noise and improves shift smoothness under full load
• Long-lasting formula: Resists breakdown from heat and oxidation, keeping your gears protected longer
• Corrosion protection: Prevents rust and wear on metal surfaces without harming seals or gaskets
• Easy switching: Compatible with all major transmission oil brands—no system flushing required when changing to this product

When to Use / Replace?

Replace transmission oil every 40,000 to 80,000 km or 2 to 4 years, whichever comes first. Check your vehicle's owner manual for exact intervals, as some modern transmissions may have longer service periods. Inspect the oil level monthly and top up if needed.

Use this oil in manual transmissions, rear differentials, transfer cases, and intermediate gearboxes. It's suitable for both synchronized and non-synchronized transmissions in passenger cars and commercial vehicles.

Frequently Asked Questions

Q: Can I mix this oil with other brands?
A: Yes, RAVENOL EPX SAE 90 GL-5 is compatible with all name-brand transmission oils. However, for best results, use the same brand consistently and avoid mixing different viscosity grades.

Q: Do I need to flush my transmission before switching to this oil?
A: No. This oil is compatible with existing transmission fluids, so flushing is not required when switching from other GL-5 oils.

Q: What's the difference between SAE 90 and SAE 80W-90?
A: SAE 90 is a single-grade oil best for moderate climates. SAE 80W-90 is a multigrade oil that flows better in cold weather (the 80W rating) while maintaining protection at high temperatures. Choose based on your climate—SAE 90 for temperate regions, 80W-90 for areas with harsh winters.
