When to Use / Replace?

Use this oil for scheduled transmission fluid changes in commercial vehicles and trucks equipped with manual gearboxes. Follow your vehicle manufacturer's service schedule, typically every 200,000–500,000 km depending on driving conditions and vehicle specifications. Check your transmission fluid level every 50,000 km and top up as needed with this same product to maintain optimal performance.

Replace the entire transmission fluid when it becomes dark, develops a burnt smell, or shows visible contamination. Cold weather operation below -30°C or severe towing may require more frequent checks.

Frequently Asked Questions

Q: Can I use this oil in my passenger car transmission?
A: This product is formulated specifically for commercial vehicle manual transmissions. Check your vehicle's owner manual or consult your mechanic to confirm compatibility with your transmission type and OEM specifications.

Q: How long does an unopened bottle last?
A: Properly stored synthetic transmission oil remains stable for 3–5 years in a cool, dry place. Once opened, use within one season to prevent oxidation.

Q: What's the difference between 75W-80 and other grades?
A: The 75W rating ensures smooth flow in cold weather (down to -40°C), while the 80 rating maintains protective thickness at high engine temperatures. This balance suits commercial vehicles operating in varied climates.
