My Buying Guides on Liqui Moly Lifter Additive Review

When I first heard about Liqui Moly Lifter Additive, I was curious if it could really help with the ticking noises and rough idling my car was experiencing. After trying it out and doing some research, I want to share my experience and what I learned to help you decide if this product is right for your vehicle. Here’s my detailed buying guide to make the process easier for you.

What Is Liqui Moly Lifter Additive?

From my understanding, Liqui Moly Lifter Additive is an oil additive designed specifically to clean and lubricate hydraulic valve lifters. These lifters can sometimes get noisy or stuck due to sludge or deposits forming inside. This additive helps restore smooth operation and reduce engine noise without the need for expensive mechanical repairs.

Why Did I Choose Liqui Moly Lifter Additive?

I chose this product because Liqui Moly is a well-known brand in automotive care, and their lifter additive has great reviews for improving engine lifter performance. It promised a simple solution to quiet down my engine noises and improve overall engine smoothness, which was exactly what I needed.

Key Features I Considered

  • Compatibility: I checked that the additive works with my engine type and oil grade. It’s suitable for both gasoline and diesel engines, which gave me confidence.
  • Ease of Use: The product is very user-friendly — just add it to the engine oil before an oil change. I appreciated not having to disassemble anything.
  • Effectiveness: I looked for evidence from other users and tests showing noise reduction and cleaner lifters.
  • Quantity: Each bottle treats up to 6 liters of engine oil, which matched my car’s oil capacity.
  • Brand Reputation: Liqui Moly’s long-standing reputation for quality additives influenced my decision.

How I Used Liqui Moly Lifter Additive

I added the entire bottle to my engine oil right before my scheduled oil change. It’s important to add it to warm oil for best results, so I ran the engine for a few minutes beforehand. After adding the additive and topping off with fresh oil, I drove normally and monitored the engine sound.

Results I Noticed

Within a few hundred miles, the ticking noises from the lifters noticeably decreased. The engine ran smoother at idle, and I felt more confident that the lifters were properly lubricated and cleaned. While it’s not an instant fix, consistent use over time brought positive changes.

Things to Keep in Mind Before Buying

  • Not a Miracle Cure: If your lifters are severely worn or damaged, this additive won’t replace mechanical repairs.
  • Regular Maintenance Needed: Using this additive periodically can help maintain lifter health, but it’s no substitute for regular oil changes and engine care.
  • Follow Instructions: Make sure to use the correct dosage and add it to warm oil for best performance.
  • Check Compatibility: Always verify that the additive suits your engine type and oil specifications.

Where to Buy and Pricing

I found Liqui Moly Lifter Additive easily available online and at automotive stores. Prices vary slightly, but it’s generally affordable given the potential benefits. Look for authorized sellers to avoid counterfeit products.

Final Thoughts from My Experience

If you’re experiencing lifter noise or want to proactively maintain your engine’s valve train, Liqui Moly Lifter Additive is worth considering. From my experience, it’s an effective, simple, and affordable way to improve lifter performance and reduce annoying engine noises. Just remember it’s part of a broader maintenance routine, not a one-time fix.
