Although I didn’t really have the chance to make any comparison in fuel consumption with the pre- and post-use of the BG 244® injector cleaner, I have definitely noticed that the engine of my Land Rover Freelander 2 runs smoother. The engine doesn’t produce any smoke, not even under pressure. I will try to test the fuel consumption difference (if any) on my next usage of the BG 245®, which I have recently purchased.
