Our new blend used since June is only the third blend in our 12-year history and the best we've ever produced. This blend was made to work with most oils, including synthetic oils. The instructions are printed below on how to use this new blend and are on our website, but, unfortunately, many people continue to follow instructions for the previous blend and do not get the savings or the benefits.
Basic Engine Cleaning
For vehicles in good condition with less than 100,000 miles. This will work for stuck rings, most stuck lifters, and many other situations that are under forced (pressurized) circulation. Not for sludge! Vehicles with more than 100,000 miles may require a second application. Click here for instructions.
Fast Track for Extreme Sludge & Extreme Oil-Burning Several factors may cause sludge or extreme oil-burning, and correcting either one is not an exact science. If you still have questions after reading our application instructions, please contact our support tech at technicalarx@gmail.com. Click here for approved oils>>
