It's an engine oil flush. When we change engine oil, only 75% is drained. Remaining 25% sticks on the Valves, Oil -lifter, Oil-chamber and other inner parts in the form of: Glazed oil, Gum and Sludge. Ru-OC Engine Flush removes these harmful residues completely without opening engine.
Thus, Ru-OC saves engine from internal damage, prolongs engine's life, improves lubrication, enhances performance and increases fuel efficiency.
