Frequently Asked Questions
What does a fuel system cleaner actually do?
A fuel system cleaner is added to the tank to dissolve gum, varnish, and carbon deposits on injectors, intake valves, and throttle bodies, restoring a more efficient fuel spray pattern and smoother combustion.
What is the difference between a fuel cleaner and a power boost additive?
A fuel system cleaner focuses on removing deposits that build up over time, while a power boost or octane additive is formulated to improve combustion and throttle response on top of a clean system. Many drivers use both together for the best result.
How do I know which additive my Honda or Mazda needs?
The right product depends on whether your engine is petrol or diesel, and the symptoms you’re experiencing — rough idle, hesitation, or reduced power. Bring your vehicle to DOHC Auto and our technicians will confirm the correct fuel system cleaner or power boost additive.
