Product Information
Full details
Carlube Petrol Injector Cleaner is an essential maintenance solution for drivers looking to restore lost engine performance and improve fuel efficiency in petrol vehicles. Designed for both fuel-injected and carburettor systems, this formula targets and removes harmful deposits in injectors and inlet ports to ensure smoother operation. While it provides immediate benefits after a single use, it is most effective when used as part of a recurring preventative maintenance routine rather than as a permanent fix for mechanical failures.

FAQs
Can I use more than one bottle at a time?
No, you should stick to the recommended 300ml dosage per 50 litres of fuel to avoid over-concentrating the additives.
Is this product safe for catalytic converters?
Yes, Carlube Petrol Injector Cleaner is designed to be safe for use in modern exhaust systems, including those equipped with catalytic converters.
How often should I use this cleaner?
While it can be used as a one-off treatment, it is recommended to use it regularly with every tank fill for the best long-term results.
Can I use this in a diesel engine?
No, this product is specifically formulated for petrol engines. Using it in a diesel engine may cause damage.
Will this help me pass an emissions test?
By cleaning the fuel system and optimizing combustion, it can help reduce exhaust emissions, which may assist in passing an MOT or emissions inspection.
Troubleshooting
No noticeable improvement in engine performance.
If one treatment does not resolve the issue, it may indicate a mechanical fault rather than a fuel deposit issue; have the vehicle inspected by a professional mechanic.
Engine still feels sluggish after driving a full tank.
Check your air filter and spark plugs, as these components also contribute significantly to throttle response and engine power.
