Features and Construction
This cleaner combines several chemical compounds that work together to clean and protect your fuel system. Each ingredient has a specific role in the cleaning process.
Active Ingredient Blend
The formula includes methanol, isopropanol, and diethylene glycol monobutyl ether as solvents to dissolve varnish and carbon. Tert-butyl peroxide acts as a stabiliser, while benzotriazole provides corrosion protection for metal components inside the fuel system.
120ml Bottle Size
The cleaner is supplied in a 120ml bottle, providing enough product for one treatment per standard petrol engine. The compact size makes it easy to store and handle, and the pour spout allows controlled addition to the fuel tank.
Uses and Placement
This cleaner is intended for periodic use to maintain fuel system cleanliness and prevent performance issues caused by deposit buildup.
Maintenance Cleaning
Add the entire 120ml bottle to your fuel tank before refuelling with fresh petrol. The cleaner mixes with the fuel and passes through the injectors and combustion chamber, lifting deposits as you drive.
Engine Performance Support
Regular use can help prevent rough idling, hesitation during acceleration, and reduced fuel economy. It is suitable for use every 3,000-5,000 miles or as part of a scheduled service.
Benefits and Buying Value
Using a fuel system cleaner reduces the need for costly professional cleaning services and helps extend the life of fuel injectors and related components.
Cost-Effective Maintenance
This product provides a low-cost way to keep your fuel system clean without specialist tools or garage visits. One 120ml treatment treats a full tank of fuel.
Performance Recovery
By removing deposits, the cleaner can restore lost engine power and improve responsiveness, especially in vehicles that have been driven mainly in stop-start city traffic.
