Purpose and Specifications

RAVENOL Transmission Oil SAE 90 is a mineral-based gear oil designed for manual transmissions, transfer cases, and differential gears that require SAE 90 viscosity. This oil provides reliable lubrication and protection under moderate mechanical stress, making it suitable for older vehicles and standard transmission systems.

The SAE 90 rating means the oil maintains proper thickness across normal operating temperatures, ensuring smooth gear shifts and consistent protection. Mineral-based formulations like this offer cost-effective performance for vehicles not requiring synthetic alternatives.

When to Use / Replace?

Replacement Interval: Most manual transmissions with mineral oil should be serviced every 40,000 to 80,000 kilometers or every 2 to 3 years, whichever comes first. Check your vehicle's owner manual for exact intervals, as some older models may have longer or shorter service schedules.

Operating Temperature Range: SAE 90 oil performs effectively between -5°C and 60°C under normal driving conditions. In extremely cold climates below -5°C, a lighter viscosity (SAE 75W-90) may be more suitable.

Shelf Life: Unopened containers typically maintain quality for 3 to 5 years when stored in cool, dry conditions away from direct sunlight.

Key Benefits

• Reliable protection for manual transmissions and differentials
• Cost-effective mineral oil formulation
• Smooth gear engagement and reduced wear
• Suitable for vehicles with standard transmission requirements

Frequently Asked Questions

Q: Can I use SAE 90 in modern vehicles?
A: Modern vehicles typically require synthetic or semi-synthetic oils with specific viscosity grades (like 75W-90 or 75W-85). Always follow your vehicle manufacturer's recommendations. Using the wrong oil type can damage your transmission.

Q: How do I know if my transmission oil needs changing?
A: Signs include difficulty shifting gears, grinding noises, or a burnt smell from the transmission. Dark or cloudy oil also indicates it needs replacement. Regular maintenance prevents costly repairs.

Q: What's the difference between SAE 90 and SAE 75W-90?
A: SAE 90 is a straight mineral oil best for moderate climates. SAE 75W-90 is a multi-grade synthetic that flows better in cold weather while maintaining protection in heat. Choose based on your climate and vehicle requirements.
