LIQUI MOLY – LIQUI MOLY Special Tec Motor Oils - Quarts and Small Sizes, including Special Tec AA Motor Oil SAE 0W16, 0W20, 5W20 and 5W30, Special Tec V SAE 0W20, Special Tec LL SAE 5W30, Special Tec B FE SAE 5W30, and Special Tec LR SAE 0W20. Picking a modern engine oil is less about brand loyalty than about matching the approval printed in the service book, and this shelf is arranged to make that easy in single-fill sizes. Special Tec AA is built for Asian petrol engines, spanning ultra-low viscosity 0W16 and 0W20 grades for the tightest modern tolerances up through 5W20 and 5W30 for slightly older designs. Special Tec V SAE 0W20 and Special Tec LL SAE 5W30 address European requirements, with the long-life formulation aimed at extended drain intervals and aftertreatment compatibility. Special Tec B FE targets low-friction fuel economy specifications, and Special Tec LR SAE 0W20 serves applications calling for that particular approval. Sticking to the specified grade also protects timing chain tensioners and variable valve timing hardware, both of which depend on stable oil pressure and clean, low-ash chemistry.
