Using a combination of ceramic compounds, this oil additive reduces friction and wear by forming a protective film that cuts down on direct metal to metal contact. This both extends the engines service life and reduces fuel consumption in both gasoline and diesel engines. Specially formulated to adhere to the internal engine's metal surfaces, which makes this great for vehicles with high pressure, cam-driven fuel pumps and engines that make excessive noise on start up.

Let engine run on idle speed for 10 minutes. Drain oil, change oil filter and re-fill with fresh high quality oil. Pro-Line Engine Flush is a development product based on highly effective state-of-the-art additive technology. These highly effective detergent and dispersant additives, in association with the carrier fluid, have been tested in the laboratory and in practical field trials for their ability to dissolve sludge and lacquer formers. All types of oil-soluble and oil-insoluble residues are brought into suspension and removed during the next oil change. An engine which has been cleaned of deposits and contamination and which is then filled with fresh oil not contaminated with old impurities can develop its full performance characteristics. Properties: Gentle and rapid cleaning Neutral to seals and other materials installed in the engine Compatible with catalytic converters Highly economical No additional environmental pollution Simple to use Contents sufficient for 5 liter engine oil capacity Fully compatible with all commercially available engine oils. Benefits: Removes deposits & residues Dissolves sludge & lacquer and isolates solid particles & liquid contaminants Improves the combustion process and restores full engine performance Prevents corrosion of unprotected metal surfaces Recovers oil lubricating properties Suitable for all gasoline and diesel engines. Step 2 - Cera Tec - Add in with your New Engine Oil Cera Tec is a high quality ceramic wear protection product which is safe for use in all engine oils. It reduces friction and wear due to ceramic compounds that withstand extremely high chemical and thermal loads. Cera Tec reduces direct metal-to-metal contact, thus increasing the engine service life. The low-friction effect reduces fuel consumption in gasoline and diesel engines. The chemicals in this specially-formulated product adhere to metal surfaces to reduce internal wear and friction, giving you peace-of-mind and saving you costly repairs in the future. Treats up to 5 liters of engine oil and provides up to 30,000 miles of protection under normal driving conditions. *Note: Not suitable for use with wet clutch applications or limited slip differentials.

It’s not easy to find small leaks caused by stone chipping, porous soldered connections or hairline fractures in the cooling system on all water-cooled engines – the only clue is in the reduced coolant level. Radiator Sealant seals these types of leaks completely, easily and in an instant and safeguards the combustion chamber against damage caused by coolant ingress.

Deposits in the radiator can lead to inefficient cooling or improper temperature readings. Long term exposure to high temperatures can cause internal engine components to warp or become damaged without proper cooling. This Liqui-Moly Radiator Cleaner reliably removes these deposits without adversely affecting the rest of the cooling system, allowing the cooling system to run efficiently, cooling the engine to proper operating temperatures.

The unique combination of proven PEA technology and the latest additive generation achieves maximum cleaning performance in the combustion chamber, in and around the injector tip, and in the entire fuel system. Furthermore, DIJectron stops the formation of new deposits so that complex injector systems always work at the highest efficiency. Regular use of DIJectron significantly reduces the risk of engine damage caused by Low-Speed Pre-Ignition (LSPI), optimizes exhaust gas emissions, and protects the fuel system from corrosion. LIQUI MOLY recommends DIJectron for modern 4-stroke gasoline direct injection (GDI) engines. Contents (300 mL) are sufficient for 50–70 Liters (13-18 gallons) of fuel. For the best results and long-term effect, add DIJectron to the fuel tank every 4.000 km (2400 miles). Properties cleans fuel system assures precise atomization improved driveability optimizes fuel consumption and exhaust emissions values excellent corrosion protection tested for particulate filters and catalytic converters
