Purpose and Specifications

Rislone High Mileage Compression Repair is a concentrated engine oil additive designed to restore lost compression and power in worn engines. This 500 ml bottle treats your engine oil to address common high-mileage problems caused by normal wear between piston rings and cylinder walls.

What it does:

• Fills scratches and grooves in cylinder walls to rebuild compression
• Frees sticky piston rings so they seal properly again
• Stops engine blow-by (gases leaking past rings into the crankcase)
• Reduces oil consumption and blue smoke from the exhaust
• Improves fuel economy and restores lost engine power
• Reduces engine noise and vibration
• Helps vehicles pass emission tests

Compatibility: Works with all petroleum-based motor oils—conventional, high-mileage, and synthetic. Safe for gasoline, diesel, and LPG engines. Not suitable for rotary (Wankel) engines.

When to Use / Replace?

Use this additive when you notice:

• Loss of engine power or sluggish acceleration
• Poor fuel economy (fewer kilometers per liter)
• Increased oil consumption between oil changes
• Blue or gray smoke from the exhaust
• Rough idle or engine noise and vibration
• Fouled spark plugs

Application: Add the entire 500 ml bottle to your engine oil. One bottle treats a typical engine oil capacity. Use with your next oil change or add to existing oil. For best results, use with conventional or synthetic motor oil in your regular maintenance schedule.

Storage: Keep in a cool, dry place. Shelf life is extended when stored properly away from extreme temperatures.

Frequently Asked Questions

Q: How long does it take to see results?
A: You may notice improved starting, smoother idle, and better power within the first few hundred kilometers of driving. Full benefits develop over several driving cycles as the additive conditions cylinder walls and frees stuck rings.

Q: Can I use this with other Rislone products?
A: Yes. Compression Repair is compatible with Rislone Engine Treatment, Engine Oil Stop Leak, Rear Main Seal Repair, and Nano Prime. If you're unsure about other additives already in your oil system, flush the engine first.

Q: Is this safe for my engine?
A: Yes. This product contains no harmful lead or metals that could damage your engine or contaminate emissions components. It's designed to work safely with all modern gasoline and diesel engines.
