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... ## Frequently Bought Together - LIQUI MOLY Oil Additive Cera Tec 20002 Ceramic Wear & Tear Protection for Petrol & Diesel Engines Smoother Engine Performance, Less Friction & Lower Fuel Consumption 300 ml - Liqui Moly Pro-Line Engine Flush | 500 ml | Oil additive | SKU: 2037 - Liqui Moly 2030 Pro-Line Gasoline System Cleaner, 500 ml, 16.91 Fl Oz (Pack of 1) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/47969229-cera-tec-3721-i-ceramic-wear-and-tear-protection-petrol](https://www.desertcart.co.za/products/47969229-cera-tec-3721-i-ceramic-wear-and-tear-protection-petrol) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-11-07*
