Recently, I decided to try Liqui Moly Lifter Additive, and here’s my detailed guide based on my experience and research to help you decide if it’s the right product for your vehicle.
What Is Liqui Moly Lifter Additive?
Liqui Moly Lifter Additive is a specialized engine treatment designed to reduce noise from hydraulic lifters and improve overall engine smoothness. It works by cleaning and protecting the valve train components, which can help resolve ticking or knocking noises caused by worn or dirty lifters.
Why I Chose Liqui Moly Lifter Additive
I chose this product because of Liqui Moly’s strong reputation in the automotive industry and the positive feedback from other car enthusiasts. My engine had started making a noticeable ticking noise, and I wanted a cost-effective solution before considering any expensive repairs.
Key Benefits I Noticed
- Noise Reduction: After using the additive as instructed, I noticed a significant decrease in the lifter noise within a few hundred miles.
- Engine Smoothness: The engine felt smoother overall, with less vibration during idling.
- Easy Application: The additive comes in a convenient bottle that I could pour directly into the oil filler neck without any hassle.
- Compatibility: It’s compatible with both petrol and diesel engines, which made it versatile for my needs.
How to Use Liqui Moly Lifter Additive
I followed these simple steps:
- Warm up the engine to operating temperature.
- Turn off the engine and add the additive to the engine oil through the filler neck.
- Run the engine for at least 15 minutes to allow the additive to circulate.
- For best results, I used it during an oil change or added it to fresh oil.
Things to Keep in Mind
- Not a Fix-All: While the additive helped reduce noise, it’s not a substitute for mechanical repairs if the lifters are severely worn.
- Regular Maintenance: I still recommend regular oil changes and engine checks to maintain optimal performance.
- Dosage: Use the recommended amount as per the instructions to avoid any adverse effects.
