LIQUI MOLY Diesel Purge | 500 ml | Fuel additive | SKU: 1811

Excellent product. Cheaper than off the shelf and quick delivery

I’ve been very pleased with this product. It arrived on time, well-packaged, and in excellent condition. The quality is solid, and it performs just as described. It’s clear that attention has been given to both design and usability. What I appreciate most is the balance between quality and value — it feels reliable and worth the price. I’ve had no issues so far, and it has met (and even exceeded) my expectations. I’d happily recommend this product to others who are looking for something dependable and effective.

Aye was Sceptical about this one as for the Price of it waited till had quarter of diesel left in tank poured full tin in drive for 30 miles didn’t use car next day my car is a 2019 Qashqai average miles per gallon 70 ? Am average 87 & 91 miles now ? Now aye don’t no about helping with knocks our helping with Smoking from car’s but am very happy with my miles as from 70 to average 87 mile up every one like that little bit more. Recommend this product for anyone with diesel engines

I haven't had much experience with Liqui Moly products but my car has now done 100,000 miles since we purchased it and I know that regardless of servicing, which I do myself, age and use will eventually catch up and cause your vehicle to run less efficiently. Using it is super simple. Just open up your fuel filler and poor it straight in. My only gripe was that there was no nozzle to put on the end of the bottle so I had to improvise a little to get it in. Once I poured it in I didn’t drive straight away as the other half needed the car. I asked her to top up the fuel so that everything would mix properly and that is pretty much it. When I eventually got to drive the car I did feel like there was a bit more power. This could easily have been a placebo but it did feel like the acceleration was was more responsive than before. Not by much but enough for me to feel something noticeable. I am going to be fair and give the product a 4-star. I purchased it to help reduce deposits in the combustion chamber and hopefully that is what it is and will do. I felt like it gave a small improvement to acceleration but I accept that it could be me thinking there is more to it than there actually is.

Good product and fast delivery. Thanks

Wow! I've been a technician for 27 years and I'm surprised how good this cleaner has worked! I am currently driving a 2.5 Isuzu Rodeo with the 4JK engine. I put an engine in it with no real precise guaranteed mileage of the vehicle it came from. It came complete with injectors and the HP pump. I coded the injectors to the ecm and she started and ran fine. After using it a few weeks I noticed it had a pretty noisy diesel knock..I knew this was an injector (s) issue.. bummer.. Do I want to have them reconditioned at £150 to £200 each! Not if I could help it... After reading excellent reviews of this product I bought two cans. I ran the fuel right down and added the contents to the tank and ran it as close to running out of fuel as I could! I then put £10 of premium diesel and stuck in the other can.. within a week the difference is beyond what I was expecting. No diesel knock..4 mpg more.. smoother idle.. Crisper low revs response.. just a treat to drive now! I'm not saying it's going to fix every fuel problem you have.. but it's definitely worth a shot if you are having poor performance. I will be buying more and every 3000 miles I'll be sticking another can in!

Used on my 2003 Volvo D5 engine. It has 190K on the clock. The engine was always quite noisy during idle, first thing in he mornings - vibrations sent through the body of the car. I was using Redex diesel treatment several times before. Simple staff, just pour it into the tank. The fuel consumption improved for a while but that was it. However, after this treatment... what a change! Engine purrs like a cat. It is pleasure to drive again. Feels like a new engine. Definitely recommend this product if you are comfortable with disconnecting fuel lines on your engine. The job is fiddly, there is not much room to hook the lines up together with in-line fuel filter etc. (I followed a great, detailed video on the internet provided on 'Sirobb' channel. He used 1 litre of the staff, I only used one 500ml bottle). But in the end it is definitely worth the hassle. After this experience, I believe that any cleaner that you pour down to the tank is almost worthless. Easy to do but no real results. This treatment, however, cleans the injector thoroughly because it is not diluted with the diesel fuel in the tank.

Came on time and we’ll packaged . I followed the instructions to the letter but 2 weeks later not noticed any difference at all

Perfect item and quality is good , useful for the vehicle

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.

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.

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.
