I've been using this product for a few years now, and just recently I bought a piece of equipment with an engine that was producing a lot of smoke (FPT 6.7 diesel). This type of engine tends to develop carbon buildup around the piston rings. I added 500ml of this product, and 24 hours later the engine was no longer smoking. I had the same kind of problem two years ago with another engine, and it's still running perfectly today. It's definitely worth trying this product!
