Purpose and Specifications

GAT Engine Oil Stop Leak 300ml is a powerful additive that quickly stops oil leaks in petrol and diesel engines by softening and regenerating rubber and plastic gaskets, keeping them flexible to seal leaks at bearing seals and valve covers. This mid-range GAT product treats up to 7 liters of engine oil, using just 50ml per liter, and works during normal driving - drive at least 300km for best results. It reduces friction and wear, stabilizes oil thickness across temperatures from -30°C to 150°C, and prevents oil breakdown, boosting engine reliability without disassembly.

When to Use / Replace?

Use when you spot oil spots under your car or low oil levels between changes (every 10,000km or 12 months). Add the full 300ml bottle to warm engine oil via the filler cap, then drive normally. One treatment lasts up to 20,000km or 2 years; reapply if leaks return. Shelf life is 5 years unopened. Compatible with all mineral, semi-synthetic, and full synthetic oils in turbo or non-turbo engines.

• Stops leaks fast without mechanic visit
• Softens seals for lasting protection
