Purpose and Specifications

RAVENOL LS 75W-90 is a premium semi-synthetic gear oil designed for limited slip differentials (LSD), manual transmissions, and hypoid gears in cars, trucks, and historic motorsport vehicles. It meets tough standards like API GL-5 LS, MIL-L-2105D, and ZF TE-ML 05C/05D, ensuring smooth power transfer and protection under heavy loads.

This 1-liter bottle delivers key benefits: superior wear protection for gears, excellent limited slip performance to prevent chatter, rust and corrosion resistance, no foaming for consistent lubrication, and fuel savings through reduced friction. It flows easily at cold starts down to -42°C and stays thick up to 150°C+ operating temps, keeping your drivetrain reliable in extreme conditions.

• Perfect for front/rear differentials, transfer cases, and non-synchro gearboxes
• High oxidation stability extends service life up to 100,000 km or 3 years under normal use
• Shelf life: 5 years unopened in cool, dry storage

When to Use / Replace?

Use RAVENOL LS 75W-90 if your vehicle manual specifies GL-5 LS gear oil for limited slip diffs or high-stress transmissions. Ideal for performance driving, towing, or harsh weather where standard oils fail.

Replace every 60,000-100,000 km or 24-36 months, or sooner if you notice gear noise, slipping, or leaks. Always check fluid level monthly during heavy use.

FAQ

Is this oil safe for my limited slip differential?
Yes, its special LS additives eliminate differential chatter and ensure smooth locking action in self-locking hypoid gears.

Can I use it in manual transmissions?
Absolutely, it's proven for manual gearboxes, transfer cases, and axles calling for 75W-90 GL-5 LS specs.

What if my car needs GL-4 instead?
Stick to your manual; this GL-5 LS oil is for high-pressure hypoid gears, not lighter GL-4 applications.
