Liqui Moly Diesel Purge

I used it when the tank was a quarter full and the results were amazing. The car no longer lags, and emits less smoke. My car is a 2005 BMW 32d 178,000 miles and drives all over UK

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.

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.

Worth the money. Car maintenance in a bottle, if you like your car then look after it. I recommend this

Bought this after getting some decidedly dodgy diesel. Did exactly what I wanted, seems to have cleaned out the system and helped stop fuel starvation at the injectors.Saved a strip down

Good addative

have not used yet.

Must have addition to any regular service imo
