Good product have regularly used for my vehicles, though this deal seems to be a good price Review: Seems to have improved my 2016 mercedes sprinter performance - Seems to have improved the performance of my mercedes sprinter. Used with around 50ltrs of fuel & run for approx 2 hours and then another drive the next day. The engine started running very lumpy & was very concerned, spoke to a mechanic and was told this can be normal and run with fresh fuel. All seems good and running without missing firing. Seems to have better power. ## Features - Contains amides, C18-unsatd., N-[3-(dimethylamine)propyl].

However, it is something that you might want to check with the manufacturer. If you use fuel from a recognised oil company, like shell or BP etc. you don’t need to use this cleaner as the additives are already in your fuel. If you use supermarket fuel like Asda or Sainsburys, then you would want to use an additive, but like I said, check with your manufacturer first. **Q: How does the MPG gains maintain for the full 4000 miles before the recommended time to add a new bottle to it?** A: I renew after approx. 3500 miles and am satisfied with the MPG since I have been using the product. An approx. gain of 3/4 MPG. **Q: Is it safe for BMW x1 2016 diesel engine ?** A: Don’t see any reason why not, added to Mini Countryman Diesel engine, which is the same I believe **Q: do i use this before or after filling in full tank?** A: I take it with me when I’m filling the tank so I can pour it in after the petrol ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well *by E***S on 28 April 2026* Exactly as described.
