These advanced olefin copolymers are designed to fill microscopic scratches and grooves in cylinder walls, a common issue in worn engines. Unlike generic additives, this formula focuses on rebuilding compression and restoring lost power by ensuring a tighter seal between piston rings and cylinder walls. It's formulated to meet severe passenger car and truck engine requirements, offering a targeted solution for age-related engine wear. **Ideal for Older Vehicles; Skip if Engine is Recently Rebuilt** — This product is perfect for owners of older vehicles experiencing reduced engine performance, oil consumption, or failed emission tests due to normal wear. If your engine has been recently rebuilt or is in near-new condition, this additive may not provide significant benefits and could be unnecessary. It is designed to address issues arising from accumulated mileage and wear, not for brand-new engines. ## How to use 1. Ensure your engine oil is at the correct level. This product is designed to be added during an oil change, or at any time the engine oil is at the operating level. — Prepare for Addition 2. Pour one 16.9 oz (500 ml) bottle into the engine oil filler opening. This single bottle treats 4-6 quarts (3.8-5.7 Liters) of engine oil. — Add the Product 3.
