Wow. I'm a believer in this stuff . I wish I had some way to prove what I feel. I ordered 3 cans of the net when I found them on sale. I ran two cans through a used BMW I bought that I'm pretty sure didn't see and fuel system cleaner in it's life before me. I had a stumble/shudder on acceleration that is completely gone now after two cans
. Well worth it IMO.
