Engine performance and longevity are crucial for any vehicle owner. Yet, issues like wear, friction, and inefficiency can compromise your engine’s health over time. Enter Liqui Moly Cera Tec Friction Modifier, a revolutionary additive designed to address these concerns. In this guide, we’ll explore how it works, its benefits, and how to use it effectively to ensure your engine remains in peak condition.
What is Liqui Moly Cera Tec?
Liqui Moly Cera Tec is a high-tech ceramic-based oil additive that reduces wear and friction within an engine. Unlike standard oil additives, it uses microscopic ceramic particles that bond with engine surfaces to create a low-friction barrier. This advanced formula reduces wear and enhances engine efficiency, even under extreme conditions.
Key Components:
- Hexagonal Boron Nitride (hBN): A compound known for its thermal stability and low friction coefficient.
- Oil Compatibility: Works seamlessly with both synthetic and mineral-based oils.

5 Benefits of Liqui Moly Cera Tec
1. Improved Fuel Economy
Reduced friction within the engine translates to better fuel efficiency. Studies show that engines treated with Cera Tec can achieve up to a 3% improvement in fuel consumption, which can lead to significant savings over time.
2. Reduced Engine Noise and Vibration
One of the standout benefits of Cera Tec is its ability to minimize engine noise. By creating a smoother interaction between moving parts, it reduces the clattering often associated with aging or heavily used engines.
3. Extended Engine Lifespan
Cera Tec’s ceramic particles act as a buffer, protecting internal components from wear and tear. This results in a longer engine lifespan and potentially lower maintenance costs.
4. High-Temperature Resilience
Engines subjected to high temperatures, such as in performance or turbocharged vehicles, greatly benefit from Cera Tec’s thermal stability. It maintains its protective properties even under extreme heat, ensuring optimal performance.
5. Versatility Across Applications
This additive isn’t limited to standard automotive engines. It’s compatible with:
- Manual transmissions
- Compressors
- High-performance engines

How to Use Liqui Moly Cera Tec
Applying Cera Tec is a straightforward process, but proper steps ensure maximum effectiveness:
Step 1: Preparation
Before application, warm up your engine to operating temperature. This ensures the oil is viscous enough to mix thoroughly with the additive.
Step 2: Application
Shake the Cera Tec bottle well and pour it directly into the engine oil through the oil filler. The recommended dosage is one 300ml bottle per 5 liters of engine oil.
Step 3: Engine Operation
After application, drive the vehicle as normal. Cera Tec immediately begins bonding to the engine’s metal surfaces, and you’ll notice the benefits within a few hundred kilometers.
Maintenance Tip:
Cera Tec’s protective effects last up to 50,000 kilometers (about 30,000 miles), making it a long-lasting solution for engine care.

Real-World Results: What Users Say
Enhanced Performance
Many users report a noticeable difference in their vehicle’s responsiveness post-application. Acceleration feels smoother, and gear transitions in manual transmissions become less jerky.
Longevity and Cost Savings
Some drivers have used Cera Tec in high-mileage vehicles with exceptional results, delaying costly repairs or rebuilds. Engine inspections reveal less wear and better overall health compared to untreated engines.
Noise Reduction Testimonials
A recurring theme in reviews is the reduction of engine noise. Drivers of older vehicles report their engines sound and feel like new after just one treatment.
