Best Liqui Moly Diesel Additives in 2026

Dissolves and clean fuel deposits and sticky residues from gas and diesel fuel injectors, carburetors, and combustion chambers

Package dimensions :5.0" L x5.0" W x8.25" H

Does NOT have harsh detergent or abrasive chemicals that can harm your engine

Motor oil additive - Liqui Moly MoS2 anti-friction (300 ml. Can).Fit Type: Universal

Forms High load-bearing film of lubricant on all friction surfaces

You will be surprised at how much better your engine sounds and how controlled it will be even at very high RPM

EXTEND THE LIFE OF YOUR VEHICLE: zMAX Engine & Fuel formulas are simple and easy to use. Micro-lubrication soaks into metal surfaces, which improves lubricity and reduces carbon deposit build-up while boosting performance and protecting vital vehicle parts.

ENGINE EFFICIENCY: Add zMAX Engine Formula to gain efficient combustion resulting in more power. Use the engine treatment at your routine oil change or every 6k miles to reduce engine wear, lower emissions and keep your engine running smoothly.

FUEL CONDITIONER: Pour zMAX Fuel Formula in the fuel tank to lubricate and maintain a clean fuel injector system. It improves fuel efficiency and performance and conditions the pumps and nozzles reducing carbon residue from the valves or pistons.

Improves Power – Original Stiction Eliminator restores lost engine power and compression by removing sludge and varnish deposits from engine components, and neutralizing harmful acids that cause corrosion

Protects Engine Components – Original Stiction Eliminator reduces engine wear and cures and prevents symptoms of stiction and low-quality engine oil including failing HEUI injectors, black smoke, hard starts, and weak turbo boost

Cleans Fuel System – Diesel Extreme deeply cleans any diesel fuel system, safely removes and prevents diesel injector deposits, and boosts cetane

GROUNDBREAKING: Made in the USA – TriboTEX is a revolutionary engine oil additive. It contains synthetic nanoparticles developed with funding from the U.S. Department of Energy, NASA, & the National Science Foundation.

QUIETER & SMOOTHER PERFORMANCE: Reverses wear in bearings by building a diamond-like carbon coating.

UNIVERSAL: Compatible with all types of motor oil and can be used in gas or diesel engines. Use for both old and new cars. It is an excellent engine booster.

Suitable for all commercial motor oils in gasoline and diesel engines with and without diesel particulate filter (DPF).

Tested safe with catalytic converters and turbochargers.

The MoS2 low-viscosity engine oil creates a heavy-duty lubricant film on all frictioning and sliding metal surfaces.

Highly effective additive that reduces the build-up of particulates and thus increases the service life of the diesel particle filter

Suitable for diesel vehicles with diesel particle filters, provided these have not already been equipped with an electronically controlled additive tank system for filter regeneration (as used by Citroen and Peugeot, for example)

Add the diesel particle filter protector to the fuel immediately before filling up after every 2,000 km

Special combination of additives for cleaning and removal of sediments and typical impurities in the intake system and combustion
