I think it is great that before and after photographs are being displayed so that we can see if Kreen is really effective or not in cleaning an engine. How many people do this? I can remember waiting it seems like forever for people to provide before and after photographs for another engine cleaner that I once believed in. And Kreen is about half the price of that product.
 
He threw a fit in an arx thread because there were none...

No before valve train pics.

No after valve train pics.

No compression readings before/after.

Why the different standards?

You are doing a great job electrolover. I have not seen photographic proof for an engine cleaner here too often. Before and after photographs, compression testing, and UOAs and VOAs are pretty much what we have to demonstrate that an oil supplement or an engine cleaner really works.

It seemed like I waited years in the case of another engine cleaner for the photographic proof to appear. And I never saw any real evidence that engine cleaner really worked.

Soon enough we should have adequate proof for some of these products.
