Purpose and Specifications

LIQUI MOLY 1414 is a fully synthetic gear oil (SAE 75W-90, API GL5) designed for high-load manual transmissions, auxiliary drives, transaxles, and hypoid axle gears. This premium 1-liter oil ensures smooth gear shifting, maximum wear protection, and reliable lubrication even under extreme conditions like heavy towing or high-speed driving.

It flows easily at cold starts down to -40°C for quick protection, stays thick at high temps up to 150°C, and resists breakdown for quieter operation and less vibration. Outstanding corrosion protection keeps gears clean and extends component life.

• Smooth, precise shifting with reduced effort and noise
• Maximum wear protection for high-pressure gears
• Wide temperature range: Handles extreme heat and cold
• Meets MIL-L 2105 C/D standards for military-grade durability

When to Use / Replace?

Use LIQUI MOLY 1414 in vehicles requiring GL5-spec gear oil, especially modern transaxles without limited-slip differentials. Ideal for cars, trucks, and SUVs under heavy loads or frequent temperature swings.

Replace every 60,000-100,000 km or 3-5 years, or sooner if you notice grinding gears, hard shifting, or unusual noise. Shelf life is 5 years unopened when stored cool and dry.

FAQ

Q: Is this safe for my daily driver?
A: Yes, perfect for everyday use in manual transmissions needing GL5 protection - smoother shifts and longer gear life.

Q: Can I mix it with other oils?
A: Fully miscible with mineral gear oils during changes, but for best results, flush and use full synthetic.

Q: What if my car has a limited-slip differential?
A: Check your manual - this GL5 is for standard hypoid gears; use specialized LSD oils if required.
