## 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
