One bottle is specifically designed to clean the fuel injectors, removing deposits. The second bottle is formulated to help reduce smoke emissions by ensuring a cleaner and more complete combustion process.

When used as directed for petrol engines, this product is safe for your fuel system and engine. It is formulated to remove harmful deposits without causing damage.

Results can vary. You may notice improvements in engine smoothness and performance within a few hundred miles of driving after application. Smoke reduction may also become apparent during this period.

It is generally not recommended to mix multiple fuel additives simultaneously, as their interactions can be unpredictable. Use this product on its own.

Ensure the product was added to a sufficient amount of fuel (at least a quarter tank). Multiple treatments may be required for heavily fouled injectors. If problems persist, consult a mechanic as there might be a mechanical issue.

Confirm the product is being used in a petrol engine. Some types of smoke may be caused by issues other than fuel delivery or combustion, such as worn piston rings or valve seals. Consult a mechanic for diagnosis.

This can sometimes occur as deposits are being dislodged. Drive the vehicle for at least 20-30 miles. If the issue continues or worsens, cease use and have the fuel system inspected.
