Does what it SHOULD do

There is no magic bullet out there. No matter what the infomercials or your friends tell you. There is nothing that is going to improve your fuel mileage or make your car do things the manufacturer didn't put on the sticker.

There are products that will fix problems, and this is one of them. Techron is designed to clean fouled up fuel systems, nothing more, nothing less. My car has an aftermarket catalytic converter (due to the original one dying and not wanting to buy a very expensive original manufacturer converter.) As a result, I get the dreaded p0420 code consistently on my car. Basically, my car isn't impressed with the job my aftermarket converter is doing. (There is a very slim threshold for the sensors for your converter, so while my converter works well enough, it is just below my factory converter's ability.)

I have a code scanner, and about every two weeks the code comes back. Frustrating. I filled up my tank and added about half a bottle of Techron. The code immediately went away and hasn't come back in a full year.

Can I explain why it worked and did what it did? No, but it worked. $10 bottle of Techron vs. buying an almost $1,500 converter. You know, I don't know much about cars, but I do know how this product worked for me.

It is what it is. Does what it's supposed to do. Wish it was a bit wider but it will work. Would buy again if I needed one.

Nothing special about this hole-punch. It works just like it should and does exactly what I need it to do. Only thing I don't like is the bottom cover tends to come off a bit easily, not a big deal though.

Does exactly what it should do at a fair price. It feel a little light, but I have no concerns about durability.
