## Questions & Answers

**Q: Suitable for mercedes W123 240D?**
A: It depends. LiquiMoly is not suitable for adding to the fuel tank. You can do that, but it will have limited efficacy. If your 240D has a fuel filter inside the engine bay, you need to fill up the filter with LiquiMoly, arrange the fuel input and return pipes so they form a loop (excluding the fuel tank), and run the engine on LiquiMoly alone. This will clean your injectors. With your engine being of an era before OBD2 diagnostics, you will not be able to physically monitor the change in injector efficiency - but believe me, the cleaning is real. With my engine (2008 VW BKD Pumpe Duse diesel), I can actually see the values improve using the proper software. Once the loop to the fuel tank is opened, the values drop somewhat - but the benefit is still there. MOT emissions tests are easier to pass.

**Q: hi, Can this be used in BMW X5 2012 diesel suv?**
A: I have been using it in a VW Passat 2006, works fine.  Probably will be OK in a BMW.

**Q: Can this be poured into the fuel tank?**
A: It can be but the more fuel there is in the tank the more diluted it will be
I believe its meant to be run on a loop through the injectors- so used neat
I wasn't able to do this on my volvo v70 d5 so I removed the fuel filter and filled the cup with diesel purge, then added the remainder to the tank

Very good product

### ⭐⭐⭐⭐⭐ It worked!!
*by J***N on 21 October 2020*

I have a series 3 Land Rover with a 200 Di engine in it, which has done around 160,000 miles. Runs like a dream but was blowing out a fair bit of black smoke on flooring the accelerator. First I put a good dose of Hydra Diesel Power Blast in the tank and gave it a good Italian tune-up. (A high speed blast up the road to blow the cobwebs out) It came back much better but still some smoke. Then I did a proper purge by dipping the fuel and return pipes into the Liqui Moly Diesel Purge, which I had transferred into a clear plastic container so that I could see the level, and running the engine for 20 minutes at varying engine speeds. Result: smoke level reduced to almost nothing, much to my delight and relief as MOT due next month. Recommended product by me, an ex-mechanic.
