On a Testé l'Additif Carburant, le Décrassant Moteur & le Traitement Injection — Un Gagnant Clair!

🔬 I tested 3 fuel additives over 30,000 km — Here's what really happened A €12 fuel additive. An €18 engine cleaner. A €45 professional injector treatment. Same car. Same engine. Same driver. Over 30,000 km in real-world French driving conditions. Lab results to prove it. In France, engine additives represent a €340 million market. Each product promises to clean your injectors, reduce your fuel consumption, and revitalize your engine. But unlike pharmaceuticals, no independent validation is required before they are put on the market. Only one of the three tested products produced measurable and documented results. Another showed improvements... which disappeared in less than 5,000 km. And the third — the best-selling, most popular one in supermarkets — produced absolutely no measurable effect on our lab instruments. Modern downsized engines (1.0 and 1.2L turbo), which power the majority of recent French vehicles, accumulate deposits much faster than their naturally aspirated predecessors. High-pressure direct injection, short trips, and insufficient warm-up time are all reasons why the issue of additives is particularly critical today. In this video: ✅ Why fuel additives aren't regulated like other products ✅ What makes modern turbo engines unique in terms of deposits ✅ The complete test with lab results over 30,000 km ✅ Which of the 3 products is really worth the price — and which ones to avoid If you want to know if the products you buy at the gas station are really worth the €80 you spend every winter, this video will change your perspective. 👍 Like the video if it saved you from a bad purchase. 🔔 Subscribe for independent, well-researched and unfiltered car reviews.
