Best Liqui Moly Fuel Additives in 2026

Product 1: Mixable with all commercially available motor oils

Product 1: Stable even under high thermal and dynamic permanent loads

Product 1: No deposits and absolutely compatible with all commonly used filter systems

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

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

Prevents gelling down to -40°

Removes water and helps prevent corrosion in the fuel system

Lowers Cold Filter Plugging Point (CFPP) as much as 36 degrees

Contains one application of oil and fuel system UV leak detection dye

For use in engine oil transmissions power steering systems and gas and diesel fuel systems

Compatible with all weights of petroleum based lubricant

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.

Rebuilds worn metal and protects against future wear for 62,000 miles.

Reduces fuel consumption (up to 30% at idle, up to 15% under normal driving); Increases oil pressure in the system to the nominal value.

Levels and increases compression in cylinders. Increases engine power and improves acceleration.
