XADO Engine Oil Stop Leak 250ml – Seal Conditioner & Gasket Restorer for All Engine Types

Stop Oil Leaks Before They Become Expensive Repairs

Oil seeping from aging gaskets and seals is one of the most common — and most ignored — engine problems. Left untreated, even a minor leak leads to low oil levels, increased wear, and eventually a costly teardown. XADO Engine Oil Stop Leak (250 ml) is a targeted oil additive that works from the inside out: its active components penetrate and revitalize hardened rubber seals and gaskets, restoring their original elasticity and sealing performance — without any disassembly.

How It Works

The formula contains specialized seal-conditioning agents that are absorbed by rubber sealing materials under normal engine operating conditions. As the oil circulates, these agents gradually restore the flexibility and dimensional geometry of shrunken or hardened seals, improving the seal-to-metal contact and closing the gaps where oil escapes. The sealing effect is typically noticeable within 190–300 miles of normal driving.

Key Benefits

• Restores Rubber Seal Elasticity — revitalizes hardened, shrunken, or brittle gaskets and O-rings
• Stops Active Oil Leaks — seals existing leaks from the engine oil system
• Prevents Future Leaks — conditions seals before they fail, ideal as a preventive treatment
• Improves Seal-to-Metal Contact — restores proper compression and sealing geometry
• Eliminates Costly Repairs — avoids the need for gasket replacement or engine disassembly in many cases
• Turbocharger Safe — compatible with all turbocharged engines
• Universal Compatibility — works with all motor oil types: synthetic, semi-synthetic, and mineral

When to Use

• When oil spots appear under the vehicle or oil level drops unexpectedly
• Before winter — as a preventive measure ahead of sharp temperature drops that accelerate seal shrinkage
• At each oil change as a seal maintenance treatment for high-mileage engines

Compatibility

• All gasoline and diesel engines: automobiles, motorcycles, marine engines, and stationary installations
• Safe for turbocharged engines
• Compatible with all motor oil types

How to Use

1. Warm up the engine to normal operating temperature.
2. Add the entire 250 ml can directly into the engine oil.
3. Drive in normal operating mode — the sealing effect develops within 190–300 miles.
