Purpose and Specifications

STP Petrol Treatment is a powerful fuel additive designed to clean your gasoline engine's fuel system, fighting carbon, gum, and varnish deposits that build up over time. This 200ml bottle treats up to 132 liters of petrol, using high-quality jet fuel as a carrier to deliver active ingredients deep into injectors and intake valves for smoother performance and better fuel economy.

• Cleans fuel injectors and valves: Removes harmful deposits to restore smooth acceleration and reduce rough idling.
• Improves fuel quality: Enhances petrol efficiency, helping you save gas and extend engine life.
• Prevents issues: Inhibits corrosion, reduces friction, and stops ethanol deposits for reliable operation in everyday driving.
• Easy to use: Pour the entire contents into your tank before or after fueling; safe for all petrol engines including capless fuel systems.

Shelf life is typically 3-5 years when stored in a cool, dry place away from direct sunlight (0°C to 30°C optimal).

When to Use / Replace?

Use STP Petrol Treatment every time you fill up your tank or every 5,000 km for maintenance to keep your engine running clean and efficient. Ideal if you notice rough idling, hesitation during acceleration, or dropping fuel economy—add it right away for quick results. Replace or re-treat every 3-6 months or 10,000 km, depending on driving conditions like short trips or stop-and-go traffic.
