When to Use / Replace?

Replace your transmission oil every 40,000 to 80,000 kilometers or 2 to 3 years, whichever comes first. Check your vehicle's manual for exact intervals. Use this oil if your vehicle requires SAE 80W-90 grade transmission fluid and operates in high-stress conditions like towing, frequent city driving with heavy loads, or off-road use.

This oil is ideal for European vehicles, commercial trucks, and any manual transmission requiring GL-5 rated protection.

Frequently Asked Questions

• Can I use this in my limited-slip differential? Yes, but verify your vehicle requires the standard GL-5 version. WOLF also makes an LS variant specifically for limited-slip differentials if your manual specifies it.
• How long does this oil last once opened? Store in a cool, dry place. Unopened containers remain stable for several years. Once opened, use within 6 months to maintain performance.
• Is this suitable for automatic transmissions? No. This is formulated exclusively for manual transmissions and differentials. Automatic transmissions require ATF (automatic transmission fluid).
