I can only tell you that it is not related?

This product, physically and mechanically does not make your "fc go crazy". One way or the other, it should reduce your engine's FRICTION and not increase friction therefore increasing fuel consumption. Unless a qualified mechanic can give me a valid reason for this product to increase fuel consumption in ANY way, I will stop selling this product. Simple.

What I suggest? Come and see me and I'll try my very best to tell you what is wrong with your car if your mechanic's incompetency is being burdened on the reputation of my product as what most mechanics always do. At the most; Change mechanic.
What say you? Come see me? FOC
