I swear that Howes Meaner Kleaner made a big difference in the way my trucks runs. Maybe it only cleaned my injectors, but I've been using PS & MMO from day one and nothing I could notice. Then one 8oz. of Howes and I could tell the difference. I'll never use anything else, but that's not what I'm here to say. If you do use Howes, they are offering a FREE Howes pocket knife.
