Frequently Asked Questions

How often should I use a fuel system cleaner?

For routine maintenance and to prevent deposit buildup, it is generally recommended to use a fuel system cleaner every 3,000 to 5,000 miles, or roughly every oil change interval. For vehicles experiencing performance issues, a high-concentration 'shock treatment' may be used immediately.

Are fuel system cleaners safe for turbocharged or direct-injection engines?

Yes, high-quality fuel system cleaners (especially those containing PEA) are highly recommended for modern direct-injection (GDI) and turbocharged engines. GDI engines are particularly prone to carbon buildup on intake valves, and regular cleaning is crucial for maintaining performance.

Will a fuel system cleaner improve my gas mileage?

If your engine has accumulated significant deposits, cleaning the fuel system can restore the proper fuel spray pattern and combustion efficiency. This often results in a noticeable improvement in fuel economy, restoring it to factory specifications.

What is the difference between a fuel treatment and a fuel system cleaner?

A fuel system cleaner is formulated with high concentrations of detergents (like PEA) to actively remove heavy deposits. A standard fuel treatment or stabilizer is typically used for lubrication, moisture removal, or fuel stabilization during storage, and generally contains fewer aggressive cleaning agents.
