Not Bad
Expensive for what it is however I do believe it has started to clean my fuel system out, not been using it long but the engine does idle better and the engine runs smoother.
Not even looked if it has changed my MPG.
I have used other fuel additives in the past and would say this is not better or no worse but you can get other cheaper.
I purchased this as I drive a Nissan and Nissan dealer ships offer this as a service so thought I would try it.
