Bought a bottle and added it to my gas and now my car is running rough almost broke down on me. I don't recommend using this companies products. My car was fine before I added this product. I purchased the product in order to clean out my system and now something is wrong with my car because of this product. My car is now sluggish, emitting a strange odor, no power when trying to accelerate, very nerve racking experience. I have read other complaints about this product after the fact of purchase. Now I feel like I'll be without a vehicle due to this product.
