I use APC+ at 4:1 every weekend on wheels, tires, and wells and I really do get good results. It doesn't foam at all when using my Daytoa and Mothers brushes, which really threw me off at first, but now I rather like it. Doesn't seem like there's as much slinging of the product when there's less foam. If you've got really bad wheels/tires to start with, you may need to use a stronger product for the first clean but this stuff is great for routine care, and a gallon allows me to cut it how I like and use it anywhere I want in the car. I did both mine and my wife's engines with it between Saturday and Sunday.
