Purpose and Specifications

GAT Nano Engine Protect & Seal 300ml is a powerful additive that stops engine oil leaks by keeping O-rings and shaft seals soft and flexible. It forms a tough nano anti-friction layer on metal parts, slashing wear by up to 50% in high-heat conditions over 100°C, while fighting rust, gunk buildup, and acid damage for smoother running.

Perfect for all petrol and diesel engines, including turbos, common rails, and those with catalytic converters or particulate filters. One 300ml bottle treats up to 5 liters of new oil (60ml per liter) after every oil change, every 10,000-15,000 km or 12 months. Also works in gearboxes, differentials, and power steering at 1:10 ratio. Shelf life is 3-5 years unopened.

When to Use / Replace?

• Use after oil changes or when noticing oil spots under your car, higher oil use, or rough idling – add to warm engine for instant protection.
• Ideal for engines over 100,000 km, high-mileage vehicles, or extreme temps from -30°C to 150°C.
• Replace with every oil change; one bottle lasts a full service interval up to 15,000 km.
