This section answers common questions about using Bardahl petrol additives, including suitability, application and how regular use can support cleaner running and improved engine performance.
What are Bardahl petrol fuel additives and why should I use them?
Bardahl petrol additives are chemical treatments designed to clean and protect petrol fuel systems, enhance fuel quality, support combustion, protect components, and improve performance. They help prevent deposits, maintain optimal engine functions, and improve efficiency.
How does Petrol Fuel Treatment improve engine performance?
Bardahl Petrol Fuel Treatment lubricates the upper cylinders and rings, helps prevent valve and seat wear, disperses water from the fuel, improves cold starts, limits fuel overconsumption and reduces exhaust fumes, overall promoting smoother performance and longevity. It is suitable for all petrol engines including injection, carburettor and turbocharged systems.
What benefits does Octane Booster provide?
Bardahl Octane Booster is formulated to increase the octane rating of petrol fuel, which helps improve combustion efficiency, increases engine power and responsiveness, prevents pinking and auto-ignition, and protects valves and seats from wear.
What is the role of Petrol Injector Cleaner and Petrol 5 in 1 Cleaner?
Petrol Injector Cleaner targets fuel injectors and helps remove carbon deposits to restore efficient spray patterns and improve combustion.
Petrol 5 in 1 Cleaner is a multi-purpose cleaning additive that cleans the fuel injection system, injections pump, turbo, EGR valve, exhaust valves and catalytic converter, aiding performance and emissions while preventing costly repairs.
