- Pour the entire contents of the 20 fl oz bottle directly into your vehicle's fuel tank.

5. Maintenance Schedule
For best results and continuous protection against deposit buildup, use one bottle of Chevron Techron Concentrate Plus Fuel System Cleaner every 3,000 miles or at every oil change interval.
This product is suitable for use in all gasoline engines, including carbureted, port fuel injected, and direct injected engines. It is also safe for catalytic converters and oxygen sensors.
6. Troubleshooting
- Rough Idle, Engine Surge, Hesitation: These symptoms are often caused by fuel system deposits. Using Techron Concentrate Plus can help reduce and eliminate these issues by cleaning the affected components.
- Poor Cold Start Performance: Deposits can hinder proper fuel atomization during cold starts. This cleaner improves cold start performance by ensuring injectors are clean.
- Reduced Fuel Economy: Clogged fuel injectors and dirty intake valves can lead to inefficient fuel combustion. Regular use of Techron Concentrate Plus helps restore lost fuel economy.
- Spark Plug Fouling: Excessive deposits can lead to spark plug fouling. This product helps prevent and reduce such fouling.
If symptoms persist after several tanks of treated fuel, consult a qualified mechanic for further diagnosis.
