Look for cleaners that specifically mention:
* PEA (Polyetheramine): This is a highly effective cleaning agent found in many premium fuel injector cleaners.
* Compatibility with your fuel type: Ensure it's designed for gasoline engines. (Your Lincoln LS uses gasoline.)
Recommended Brands (check for current formulations):
* Chevron Techron Concentrate: Widely considered one of the best.
* BG 44K: Another highly reputable option, known for its cleaning power.
* Red Line SI-1 Fuel System Cleaner: A strong contender, often praised for its effectiveness.
Important Considerations:
* Follow the instructions carefully. Each product has specific usage instructions regarding the amount to add and the frequency of use. Overusing it won't necessarily yield better results and could even be harmful.
* Consider a professional cleaning. For severe fuel injector issues, a professional fuel injector cleaning at a reputable auto repair shop might be necessary. A cleaner is preventative maintenance and for less serious issues.
Don't solely rely on the cleaner to solve a major performance problem. If your Lincoln LS is experiencing significant issues like rough idling, poor fuel economy, or misfires, a thorough inspection by a mechanic is recommended to determine the root cause before using a fuel injector cleaner.
