Understanding STP Fuel Injector Cleaner

STP Fuel Injector Cleaner is a popular fuel additive designed to clean and maintain your vehicle's fuel injectors. Clogged or dirty injectors can lead to decreased fuel efficiency, rough idling, and poor engine performance. This cleaner helps restore optimal injector function. Using it correctly is key to maximizing its benefits.

When to Use STP Fuel Injector Cleaner

You might consider using STP Fuel Injector Cleaner if you experience any of the following:

Rough idling: Hesitation or shaking when the engine is at idle.
Decreased fuel economy: Noticing significantly lower gas mileage than usual.
Poor acceleration: Sluggish performance when accelerating.
Check engine light: A illuminated check engine light, especially if related to fuel system issues.
Preventive maintenance: As part of routine maintenance to keep your fuel injectors clean and working optimally.

It's important to note that if you have a persistently illuminated check engine light, you should consult a mechanic to diagnose and address the underlying problem before solely relying on a fuel injector cleaner.
