Auto-Rx Customers Questions & Answers

Not all sludge is created equal. Some motors have very hard deposits, resembling charcoal, while others can have a soft, gooey, black paste appearance. Sludge can form from a variety of reasons and will clean up at different rates based on how it was formed in the first place. A motor in the condition pictured above would warrant a 3-bottle purchase. You have already used up 2 bottles in the first phase of the Auto-Rx Plus Fast Track application You can use the third bottle to  incrementally use the third bottle for what we call the maintenance dose. The maintenance dose is merely adding 3 fluid ounces (one-fourth of a bottle) with each oil change to maintain engine oiling system cleanliness.
