Modern, high-performance engines with direct injection, suffer from an increased risk of premature ignition at low engine speeds (LSPI – low-speed pre-ignition). This can lead to engine knocking and subsequently serious engine damage. The Special Tec AA engine oils and the Special Tec DX1 engine oil were subject to an additional LSPI test for the API SN Plus+RC specification!
The Special Tex DX1 engine oil was developed specifically for the requirements of GM and Opel vehicles with gasoline engines. To some extent, other vehicle manufacturers such as Chrysler, Ford, Kia, Honda, Hyundai, Mazda, Nissan, Toyota etc., have called for a lubricant with these specifications for different types of vehicles.
The Special Tec AA engine oils are most suitable for modern Asian and American gasoline engines. They are particularly suited to long oil change intervals and high engine demands. The LIQUI MOLY Special Tec DX1 / AA Series has the following benefits:
- Reduces low-speed pre-ignition (LSPI)
- Increases engine service life
- Optimizes wear protection
- Keeps engines remarkably clean
