Purpose and Specifications

MOTUL 103996 Transmission Oil 80W-90 is a high-performance synthetic gear oil in a convenient 20-liter tank, perfect for manual transmissions, gearboxes, differentials, and transfer cases in cars, trucks, and racing vehicles. It delivers exceptional lubrication to cut friction and wear, keeping gears protected under heavy loads, high speeds, or low RPMs.

This oil stays thick and strong at hot operating temperatures up to 150°C, forming a tough film that quiets noisy transmissions and prevents metal-on-metal contact. At cold starts down to -30°C, it flows smoothly for easy gear shifts without sticking or grinding. Compatible with all seals and yellow materials in gearboxes, it offers anti-corrosion and anti-foam protection for longer life.

When to Use / Replace?

Use MOTUL 103996 in synchronized or non-synchronized manual transmissions, hypoid differentials without limited slip, and high-stress applications like racing, rallying, or towing. Ideal for vehicles operating in extreme conditions with shocks, heavy loads, or high heat.

• Replace every 60,000 km or 24 months under normal driving, or sooner at 30,000 km for racing/track use or severe conditions like frequent towing.
• Shelf life: 5 years unopened in cool, dry storage.

Frequently Asked Questions

Is this oil suitable for my daily driver? Yes, it works great for everyday cars with manual transmissions, improving shift feel and reducing noise while protecting gears for years.

Can I use it in differentials? Absolutely, for open hypoid differentials under high loads; check your owner's manual to confirm GL-4/GL-5 compatibility.

What if my transmission is noisy? This oil's high hot-temperature stability often quiets gear whine by maintaining a strong lubricating film.
