Can blindly go for it if your car needs it. *by on Reviewed in India 14 August 2021* I bought this because i was experiencing pickup issues and mileage issues in my verna fluidic 1.6 crdi diesel. I experienced the same problem 6 months prior to this, however i cleaned my egr and it was solved. Now since my egr has just been cleaned 6 months back i wasnt about to do it again and instead decided to opt for this after I had done some research which stated this could be a possible solution to buildup of carbon deposits in fuel lines and on injectors which causes a drop in power. I looked into this liqui moly diesel purge as well as the iftex product but went with this even though it was 5x the cost almost as this is a branded product and should offer better safety to the car. Anyway i got the product and used it on a somewhat empty tank(3-5L). I poured approximately 1/3 the can into the tank and drove about 10 mins and filled up 10L of diesel. I then proceeded to drive roughly 50kms and could already feel a difference in the smoothness and mileage. After driving another 80-100 km i filled up again and this time poured another 1/3 or so into the tank. I drove this time 100+kms going on the highway to let it run at steady and low rpms and also takw it to higher revs to clean out and burn away any residual buildup in the lines. By this time i could feel a difference in pickup and the cars eagerness to pull was beginning to return. After driving till the tank was pretty much empty over the next few days, i could feel the power and mileage was back to its original if not even better. Engine was smoother and quieter, power was better than ever before and mileage was amazing. I even managed 26.6kmpl on the highway and couldve possible gotten more if i had the patience. Overall I’m really happy with this product thus far. If theres anything to update in the coming months then I will. ### ⭐⭐⭐⭐⭐ Prodotto efficace, motore più fluido e meno fumo *by on Reviewed in Italy 1 January 2026* Ho utilizzato il Liqui Moly detergente per iniettori diesel su un’auto con parecchi chilometri e il risultato si è sentito già dopo pochi pieni. Il motore gira più regolare, avviamento più pronto e una leggera riduzione dei consumi. Anche il fumo allo scarico è diminuito, segno che la combustione è più pulita.Facile da usare: basta versarlo nel serbatoio prima del rifornimento. Qualità Liqui Moly confermata, prodotto serio e professionale.🌱 Caratteristica di sostenibilità: mantenendo puliti gli iniettori, il detergente ottimizza la combustione e contribuisce a ridurre le emissioni nocive, aiutando il motore a lavorare in modo più efficiente e meno inquinante. ## Frequently Bought Together - Liqui Moly Diesel Purge - LIQUI MOLY Super Diesel Additive | 300 ml | Diesel additive | SKU: 2002 - Liqui Moly Pro-Line Engine Flush | 500 ml | Oil additive | SKU: 2037 --- ## 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.be/products/651441079-1811-diesel-purge-500-ml](https://www.desertcart.be/products/651441079-1811-diesel-purge-500-ml) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-09-13*
