Purpose and Specifications

EUROLUB GEAR FLUIDE CVT 1 L is a specialized transmission fluid engineered specifically for Continuously Variable Transmission (CVT) systems. Unlike traditional automatic transmissions, CVTs require fluid that maintains precise hydraulic pressure while managing the unique demands of belt-and-pulley operation.

This yellow-colored fluid serves four critical functions: lubricates moving transmission components, reduces friction for smooth operation, cools the transmission during use, and provides hydraulic pressure for seamless gear ratio adjustments. CVT systems are more sensitive to fluid quality than conventional transmissions, making the right fluid choice essential for reliable performance and longevity.

When to Use / Replace?

Replace CVT fluid every 30,000 to 60,000 kilometers (19,000 to 37,000 miles), depending on your driving conditions. More frequent changes are necessary if you regularly drive in stop-and-go traffic, tow loads, or navigate steep hills—conditions that generate excessive heat and accelerate fluid breakdown.

For vehicles driven less than 15,000 kilometers annually, change fluid every 24 months regardless of mileage, as CVT fluid degrades over time even when the vehicle sits idle. Extended parking periods allow moisture to accumulate in the transmission, contaminating the fluid and promoting corrosion.

Operating temperatures matter significantly: CVT fluid begins to break down when transmission temperatures exceed 200°C (392°F). In demanding driving conditions—such as mountain roads or heavy traffic—transmission temperatures can reach 240°C (464°F), accelerating fluid degradation by 40-60% faster than manufacturer estimates. Degraded fluid loses its protective properties and can cause sluggish shifting, poor performance, and premature transmission wear.

Do not rely on fluid appearance to determine replacement timing. Fluid may look clean while having already lost critical protective additives. Follow your vehicle manufacturer's recommended service intervals and always use approved CVT fluid like EUROLUB GEAR FLUIDE CVT to prevent costly transmission damage.

Frequently Asked Questions

• Can I use regular automatic transmission fluid in my CVT? No. CVT systems require specially formulated fluid designed for belt-and-pulley operation. Using incorrect fluid can cause transmission failure and void your warranty. Always use fluid approved for your specific CVT system.
• How do I know if my CVT fluid needs changing? Follow your vehicle's owner's manual service schedule rather than visual inspection. Even clean-looking fluid may have lost its protective additives. If you experience delayed shifting, hesitation during acceleration, or unusual transmission noise, have the fluid checked immediately by a qualified technician.
• What happens if I ignore CVT fluid changes? Degraded fluid cannot properly lubricate transmission components or maintain hydraulic pressure. This leads to increased friction, heat buildup, accelerated wear on internal parts, and eventually complete transmission failure—a repair costing $4,000 to $6,000 or more. Regular $400 fluid services prevent this expensive damage.
