Review on 🔧 Auto-RX Plus: All-Natural Metal Cleaner for Transmissions, Engines, Differentials, and Power Steering. Expertly Cleans Internal Components. (AutoRx Amazon) by Justin Guldin

This product was used on a vintage Jeep engine years ago with amazing results. Eliminates oil leakage under the rear oil seal and timing case cover. A minor problem with oil burning also stopped. Inspected the engine after the initial treatment, the sludge is gone, it is bright and shiny. After the second revolution, the engine became significantly quieter and began to run more smoothly. After processing this time with slight variations in the instructions and on a different car, it wasn't impressive. The little sludge that was left never softened the crankshaft seals or valve guide seals so the leaks continued. Something has changed! I'm not sure I want more of this.
