I bought my car used and I would like to try it. Has anyone ever tried it?

 

I don't think it'll make much of a difference, it's really meant for higher mileage cars to clean carbon deposits ect. The previous owner should'nt have been putting anything but premium in it shich already has detergents to reduce carbon deposits in the ehad and clean injectors ect. It probbaly won't hurt anything but I doubt it'll make things better. Either
