Frequently Asked Questions

How often should I use a fuel system cleaner?

Most manufacturers recommend using a concentrated fuel system cleaner every 3,000 to 5,000 miles, or with every oil change, to keep injectors and valves free of performance-robbing deposits.

What are the signs that my fuel pump needs replacement?

Common signs include difficulty starting, sputtering or stalling at high speeds, a whining noise coming from the fuel tank area, and a noticeable drop in gas mileage or engine performance.

Is it safe to use fuel stabilizers in modern cars?

Yes, fuel stabilizers like STA-BIL are safe and highly recommended for any vehicle that will be stored for 30 days or more. They prevent fuel breakdown and protect against internal corrosion caused by ethanol blends.
