I got some on the back of some people liking it from this forum. Over the yrs I have used flashlube and much more extensively chemtech. Anyway I have never actually seen results. But I have now. And quite clearly in much better fuel economy. I am going to start swearing buy this stuff, first by swearing at the salesman at the high price, then buying it.

I think I am getting over 10% better economy even with some towing, it takes me a few weeks to get through my big tank so dont quite know just yet, but at half way I am 100km up.
