## Description

Product Description Cera Tec Ingredients oil

Review: LIQUI MOLY Cera Tec 3721 - LIQUI MOLY Cera Tec 3721 is a popular ceramic-based engine oil additive designed to provide wear and tear protection for both petrol and diesel engines. Here’s an in-depth review based on personal use, expert opinions, and user feedback: Composition and Purpose Cera Tec is formulated with ceramic compounds that are intended to reduce friction and wear inside the engine. The primary aim is to protect engine components, extend engine life, and improve overall engine performance. Key Claims and Benefits Wear Protection: Cera Tec is advertised to form a protective layer on metal surfaces within the engine, reducing metal-to-metal contact and, consequently, wear. Friction Reduction: By minimizing friction, Cera Tec aims to improve engine efficiency and potentially enhance fuel economy. Temperature Resistance: The ceramic particles in the additive are designed to withstand high temperatures, ensuring the protective layer remains effective even under extreme conditions. Noise Reduction: Users often report a reduction in engine noise, which can be a sign of reduced friction and smoother operation. Application and Use Cera Tec is compatible with all commercially available oils and can be used in both petrol and diesel engines. It’s typically added during an oil change, and one bottle is sufficient for up to 5 liters of engine oil. The additive is mixed with the engine oil and does not require any special procedures. Performance and Effectiveness Personal Use and User Feedback Wear and Tear: Many users report noticeable reductions in engine wear over extended periods. This is often observed in smoother engine performance and longevity. Fuel Economy: Some users have noticed slight improvements in fuel economy, though this benefit can vary based on driving conditions and engine type. Engine Noise: A significant number of users report quieter engine operation after using Cera Tec, suggesting effective friction reduction. Smooth Operation: Improved engine smoothness and responsiveness are commonly cited by users. Expert Opinions Automotive experts generally acknowledge that ceramic additives like Cera Tec can provide additional protection against wear, especially in high-stress or older engines. However, the benefits can sometimes be marginal if the engine is already in good condition and maintained with high-quality oil. Pros and Cons Pros: Enhanced Protection: Effective in reducing wear and extending engine life. Versatility: Suitable for both petrol and diesel engines and compatible with all types of engine oils. Improved Performance: Potential for smoother engine operation and noise reduction. Temperature Resilience: Maintains effectiveness under high-temperature conditions. Cons: Cost: Relatively more expensive than standard oil additives. Variable Results: Benefits like improved fuel economy may not be significant for all users. Over-reliance: Should not be seen as a substitute for regular maintenance and high-quality engine oil. Conclusion LIQUI MOLY Cera Tec 3721 generally lives up to its claims, providing an extra layer of protection for engine components. It is particularly beneficial for high-mileage or older engines and in conditions where engines are subjected to high stress. While the cost is higher compared to standard additives, the potential benefits in terms of wear reduction and smoother operation can justify the investment. However, it’s important to have realistic expectations and not to rely solely on additives for engine maintenance. Regular oil changes with high-quality oil and proper engine care remain essential.
Review: ⭐⭐⭐⭐⭐ Excellent product - ⭐⭐⭐⭐⭐ Excellent product After adding Liqui Moly Cera Tec, the engine became noticeably quieter within seconds as it mixed with the oil. The engine runs smoother, and I’ve also noticed a significant reduction in fuel consumption on the dashboard. Very good product for engine protection – highly recommended.

## Questions & Answers

**Q: Will this be suitable for vw touran 1.9 tdi manual 2005 ?**
A: I have used it in my 2litre tdi Nissan X-Trail at 6 years old, and 50,000 miles on the clock. It reduced winter rattle from the engine, and the engine ran a little smoother than usual, especially at cold start in winter for the first 6-7 minutes. It has no damaged any components and 2 years later the engine is running smoothly as usual. I have bought a second bottle to use at the next oil change to help protect the engine from future wear. I did not witness a reduction in fuel consumption that some have experienced. My father has an X-Trail with an older engine, and he reported not seeing much difference after using the product. My brother has a petrol Honda Civic and claimed it did not have much visible effect for him either. So, I guess the effects are largely hidden on the interior surfaces of the engine, promoting a longer service life. My mechanic has seen the surface effect of the Ceratec in the engine ans says the effect is clearly visible and the surfaces are smoother to the fingertip touch. I believe this worth giving it a try.

**Q: Can I use Ceratec on automatic transmission diesel?**
A: Yes, providing you are planning to use it in the engine and not the gearbox you will be fine. If you're planning to use it as a gearbox additive, I'd contact Liqui Moly first to make sure its ok to do so.

**Q: Can i use ceratec on petrol/hibrid dngine?**
A: Hybrid car still running and charge battery using petrol engine so I can't see why not

**Q: Can I use it with oil additive and hydraulic additive in the same time ?**
A: Yes you can.
It also can be used with an engine flush.

See you tube videos. To see what takes place. Also. It will not work immediately..... Say 100 or 150 miles after adding it you will definitely see somthing is changing...

### ⭐⭐⭐⭐⭐ Excellent product which works well as advertised
*by C***H on 6 November 2025*

This is one of the few products that consistently works well for me. I've used it in multiple vehicles over several years, including two diesel cars and two petrol-hybrid engines, and it's had a positive impact on them all. Takes about few hundred miles for its impact to be fully noticeable. In both diesel cars, Idle became smoother and quieter, less hesitant and smoother acceleration and increased mpg. The effects seem to be even better on the Toyota hybrid engines. These engines go on and off a LOT of times as the system switches between battery power and engine. After application, engine seem more alert, switching on and off much for eagerly and easily. I don't think this is a wonder product by any means. It simply does what the manufacturer claims it will do. It's not going to cure a neglected engine. It will supplement a well looked after car. It helps decrease friction between metal parts in the engine. Imagine lubing door hinges. Will be buying again.
