Why Liqui Moly?

Liqui Moly is known for precision-engineered formulas that target real-world problems. Whether it’s cleaning sensitive components or protecting internal parts, these products are designed to work effectively without overcomplicating your maintenance routine.

Featured Products and How to Use Them

Liqui Moly Hydraulic Lifter Additive

If your engine has developed a ticking or tapping noise, especially on startup, this is often caused by dirty or sticking hydraulic lifters.

What it does:
Cleans and frees up lifters, helping to restore smooth and quiet engine operation.

How to use it:

1. Add the full contents to your engine oil (make sure the oil level is correct).
2. Drive as normal, no need to change your oil immediately.
3. Results typically improve over a few hundred miles.

Top tip:
Use this before your next oil change to help clean internal components and get more out of fresh oil. Always read and follow instructions on item carefully.

Liqui Moly Air Flow Sensor Cleaner

Modern engines rely heavily on accurate air intake readings. A dirty mass air flow (MAF) sensor can lead to poor fuel economy, rough idling, or sluggish acceleration.

What it does:
Quickly removes dirt and residue from sensitive sensor components without causing damage.

How to use it:

1. Locate the MAF sensor (usually between the air filter and intake).
2. Disconnect the sensor carefully.
3. Spray the cleaner directly onto the sensor element, do not touch it.
4. Allow it to dry completely before reinstalling.

Top tip:
Clean your MAF sensor every 10,000–15,000 miles to maintain optimal performance and efficiency. Always read and follow instructions on item carefully.

Liqui Moly Diesel Purge

Diesel engines can suffer from clogged injectors and inefficient fuel combustion over time, especially with short journeys or lower-quality fuel.

What it does:
Deep cleans the fuel system, improving injector performance and restoring power.

How to use it (two methods):

Quick method:

• Add directly to your fuel tank and drive as normal.

Intensive clean (advanced DIY):

1. Disconnect the fuel lines from the tank.
2. Run the engine directly on the Diesel Purge using a suitable setup.
3. Allow it to cycle through the system for a thorough clean.

Top tip:
If your diesel feels sluggish or smokes more than usual, a full system clean can make a noticeable difference. Always read and follow instructions on item carefully.

Practical DIY Tips for Better Results

• Consistency matters: Regular use of quality additives prevents buildup rather than just fixing it.
• Start with a clean baseline: Combine products like Diesel Purge with a fresh fuel fill or oil change for maximum effect.
• Don’t ignore early signs: Small issues like rough idling or engine noise are often easy to fix if addressed early.
• Use the right product for the job: Targeted solutions deliver better results than general-purpose treatments.
