It works
This product is preventative. When I rebuilt my engine with almost 400, 000 miles on it the injectors and the intake valves were in bad shape.I use this product every other oil change and after another 100,000 miles the engine still has great vacuum and idles smooth.

When its cleaning you can smell the difference in the exhaust and feel your engine smooth out
These products make your car run smoother especially if you dont regularly buy top tier gasoline. I m in sales and drive 34,000 + miles a year mostly on open highway I have used many of the other brands but I think this is the best it's worth the few $$ !

Don't Hesitate! This Stuff if Magic!
The Berryman B-12 Chemtool is superb at cleaning all kinds of gunk from Valves and Injectors. I used this product on a 2008 VW GTI which had about 100,000 miles on it. After taking off the intake head and pulling the injectors I had so much build up, which was expected. I went ahead and ordered this as it came recommended from many car forums and the product lived up to its reputation by being able to clean with ease.I poured some in a cup and used a tooth to clean the injectors. For the valves, which were still in the engine, I cranked the crankshaft so that one cylinder's valves would close and I poured it right in and let it sit for about 15 minutes and used a tooth brush to clean it out. I pulled out so much black carbon build up it was unbelievable, but this stuff was truly magic for my valves!
