Cera Tec by Liqui Moly features a high-tech anti-wear additive, making it suitable for most 4-stroke engines (including those with turbochargers) as well as manual transmissions and compressors. It reduces friction and wear, thanks to a unique combination of ceramic compounds and chemical anti-wear agents that prevent direct metal-to-metal contact. Liqui Moly Cera Tec provides miscibility with most commercially available motor oils and is safe for catalytic converters and particulate filters (GPF/DPF), as well as belt-in-oil systems.
