Keeping your Ford Fusion’s fuel injectors clean is key to reliable performance, smooth idling, and optimal fuel economy. Whether you’re encountering hesitation, rough starts, or merely want preventative maintenance, the right injector cleaner keeps your engine in top shape. This comprehensive 1,400+ word guide explores the most effective options, usage tips, and advice tailored for Fusion owners.
Do Fuel Injector Cleaners Work?
