This worked for what I needed to. I was having a hesitation so decided to try this product. After using my car is no longer hesitating. I'm not sure how I feel about it making my gas last longer or making my car have better gas mileage. I do have an older car.

Sufficient enough.
I have no complaints about the product in particular, it didn't not help my vehicle like we had hoped, but that was just a hope.
