Product Description

CERA TEC is a high-tech ceramic wear protection product for all motor oils. CERA TEC reduces friction and wear due to ceramic compounds that withstand extremely high chemical and thermal loads. Prevents direct metal-to-metal contact, thus increasing the engine service life. The low-friction effect reduces fuel consumption in gasoline and diesel engines. CERA TEC provides wear protection for engines, transmissions, pumps and compressors. CERA TEC should be added to the oil and is self-mixing. Sufficient for 5 liters of motor oil. Provides protection up to 50,000 km. Not suitable for use with wet clutches.

Easily confused with a protein milkshake. So be careful to not leave it on the morning breakfast table like I did. Added a can to an emergency situation. Someone ran the oil dipstick dry and started complaining of a 'knocking' sound in the engine. UGH. After dumping 3 quarts of oil in the engine, I chased it down with a can of LiquiMoly Cera Tec the next day. I'll run it until the next oil change in about 3 mos. After I dumped the LiquiMoly into the engine, I started the car. The idle started to slowly creep to a crawl, to the point that I thought the vehicle was going to stall! But she kept silently purring. This stuff is either snake oil or a magic potion.

Excelente producto!, nunca había utilizado aditivos en mis vehículos, sin embargo al probar Ceratec de Liqui Moly se siente una gran diferencia en la suavidad de marcha del motor, así como la reducción en el consumo de combustible.
