Excellent Product for diesel engine’s injectors cleaning and also pickup increase very good. You fill throttle response and also some improvement in mileage. Please note that first change diesel filter and after that use diesel purge. otherwise may be blockage happened.

Perfect item and quality is good , useful for the vehicle

I have used this product 1st time for my verna fludic 2011 diesel. Before using this product my car engine was having some different kind of noise like tractor engine. mileage on highway was around about 19 KMPL to 20 KMPL. I used this product while refueling my diesel tank with 10 ltrs. i just poured this bottle with 10 ltrs diesel. After fueling with diesel purge I had run my car around about 30KM to 40KM with minimum speed limit of 80 on highway. i feel the difference after my car run 50 KM and engine noise improved and mileage increased to 22KMPL to 24KMPL on economy mode on highly. Conclusion: you can buy this product for diesel cars with advice from your service center or third party service center. NOTE: This works best for EURO 4 Diesel Engines.

Used this product in my Verna Fluidic 2016 Diesel variant. Before adding this to your fuel tank please make sure to change your Diesel filter or else this product might instead clog your injectors. After adding this entire bottle to half tank, for initial 100-125 kms did not notice any difference and I gave up on this product’s effectiveness. But then all of a sudden felt the engine a lot smoother, vibrations were reduced and noise was quite less from the engine. Even the pickup of my car was increased noticeably. I think it really served the purpose. The bottle was received to me in a dented condition but that’s completely fine. Most of liqui moly bottles are dented, even the engine flush that I ordered the bottle was dented.

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.

Very impressive, i use it in my ford ecosport deisel after 40k km done. I put it directly in the deisel tank with around 20ltr of fuel. About to 40-50 km average is drastically changed from 18.6 to 23.5 noise and vibration reduce and acceleration become very smooth. amezing product.

First time Diesel Purge user. I regularly use liqui moly diesel additive / booster. Vehicle: Hyundai Verna SX AT (Automatic) Age: 8 yrs Kms: 89,000 kms Engine oil: Syntheric (changed 1 month ago) Air and Oil Filter: Changed 1 month ago I used the entire 500 ml content directly in the almost 40L diesel present in my tank . Though I did observe a noticeable positive difference but I won't say it was a day and night one. What I found was: 2-5 kms immediate difference noticed in smoothness and the accelerator pedal felt lighter. 15-50 kms smoothness increased some more, noise levels decreased to a good extent, acceleration and aggressiveness increased to a good level and the car felt lighter to drive BUT the curve that started on a positive note with a steep incline flattened out at 50 kms without much more positive change in the behaviour of the vehicle. 50-125 kms not too much increase in behaviour. Though I did find that morning and cold starts had improved considerably bit that's about it. Rest all improvements are stagnant now. So overall after using this product for over 150 kms I didn't find this product to have a big edge over the Liqui Moly diesel booster/l additive that I regulary use. And the additive / booster costs almost half the price of the purge. Maybe my injectors and fuel system are in good condition already so I may have not noticed a big difference. Maybe people with injector / fuel system problems would have found a big difference. But this is my personal experience and I have owned quite a few diesel cars so I know pretty well how they behave.

I have a BMW F10 520d. Was extremely skeptical about using this at first. Well, I took a chance after doing some good quality research. Yes, this can be used on a BMW diesel engine cars or any other as such for that matter, but be mindful of what to do next. Okay, so I poured the entire CAN into the fuel tank, refueling in with over 30-40L diesel in. Drove my car on the highway for about 90-100 kms at a constant speed above 80kmph, letting the DPF regen kick in and such that the mixture throttles through the engine, the injectors. Result: Uff, have to say. Noted world of a difference after using this. There's far more refinement in the engine, smoother, leaner power delivery, throttle response, and better milage. Epic. This is absolutely a very good product. Tip: CHANGE the fuel filter after you utilize this product post your highway run and before refueling your car again. It's important that you do so. It's not required to carry out this purge process frequently. The process of Purge can be done every 30,000-40,000 kms. Be advised: DO NOT use any other additives to older BMW engines. They are not meant for anything else to go in. Purge is the only thing that's safe to use as far as it goes. As for more pro-tip: The thumb rule for diesel vehicles is the right oil change intervals, highway runs, paying attention to your cars behavior, and taking care of your vehicle. Hence do keep your car's intake manifold clean, do a frequent highway run for DPF regen, and engine oil, filters service intervals below every 10k kms. Yes, I definitely recommend this for any Diesel vehicle. It works really well and like a charm. I totally see the difference in how refined my car engine runs now. LiquiMoly Purge is totally worth it. LiquiMoly is just epic and on another level for its quality products. They are renowned pioneers in the automotive industry, formulating such products. Especially their engine oil. Hope you find this helpful. Thank you.

vraiment très efficace, après un premier refus au contrôle, j'ai utilisé ce produit directement dans le réservoir de la pompe et le reste dans le réservoir, résultat le taux est descendu de 3.8 à 0.9.

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.

Excellent product, value for money

Bueno reconozco mi gran escepticismo antes de adquirir este producto. Ha sido para un Opel corsa del 16. 1.3 diesel. Lo he usado de la siguiente manera, depósito en reserva, echar el producto y llenar unos 25L. Luego conducir el vehículo algo más de 100 kms a unas revoluciones concretas (entre 2000 y 2500) y de vez en cuando subir hasta 3500 para realizar un cambio de velocidad, por ejemplo de 3ª a 4ª. Bueno pues el resultado ha sido excelente, los pequeños tirones que sentía muy sutiles, han desaparecido por "arte de magia", de vez en cuando me salia fallo motor por mala combustión y no me ha vuelto a pasar. Aún no he consumido todo el depósito, pero creo que este producto ya me ha demostrado que es efectivo. Lo volveré a usar en unos 3000 a 5000 kms como mantenimiento.

Ottimo, l'ho utilizzato sulla mia Fiat Bravo 1.6 MultiJet diluendolo in appena 10 litri per una pulizia degli iniettori intensa. Non avevo mai utilizzato degli additivi ed ero titubante ma oltre ad aver reso leggermente piu silenziosa la mia auto a freddo, adesso la trovo molto piu reattiva nel salire di giri e i consumi risultano leggermente migliorati, lo ricomprerò senz'altro
