### ⭐⭐⭐⭐⭐ The best oil additive ever !!!
*by M***R on 19 February 2015*

What a fantastic product. In the past I have always used SLICK 50, but wanted to see what else was out there to help protect my Mercedes engine. I looked at a few reviews and picked on this. For the price I was not expecting much considering how much I spend on other oil additives. The bottle arrived in the timescale promised, and well packaged. I had just had the car serviced and wanted to add a bit of protection to the engine. The instructions said I could add it to the oil and as the bottle is not too large I took the chance and began to pour into the engine. First thing that surprised me was that it was like a gel and not like an oil. I poured the additive in. I made the mistake of pouring it in like an oil, which soon filled the spout to the engine. Please when you use this pour VERY SLOWLY. This will stop the spout getting blocked. I have now driven the car for a couple of hundred miles and the engine is so much quiter. (Even the wife has noticed this) I cannot recommend this enough and I have had all sorts of cars over the last few of decades and this has been my best car based purchase. I hope this helps with your choice
