Quick answer: Liqui Moly is a German brand with an oil family for every type of car. For modern Japanese, Korean and American cars choose Special Tec AA. For European cars that require approvals such as VW 504/507 or MB 229.51 choose the right Top Tec. For a strong all-round synthetic with extra friction protection, Molygen New Generation is an excellent choice. Most importantly, match the viscosity and approval in your owner's manual.

How to choose the right Liqui Moly oil
- Open your owner's manual and note the viscosity (e.g. 0W-20 or 5W-30) and approval (API SP, ILSAC GF-6, ACEA C3, VW 504 00...).
- Modern Japanese or Korean car: Special Tec AA in the same viscosity.
- European car with a DPF or GPF: Top Tec or Molygen DPF with the required approval.
- High-mileage older engine: Leichtlauf 10W-40 or Molygen 5W-40 if the manual allows it.
Molygen or Top Tec?
Molygen focuses on reducing friction and protecting the engine and suits many cars. Top Tec focuses on meeting European OEM approvals and protecting exhaust filters, so if your car is European and requires a specific approval, Top Tec is the right pick. Both are fully synthetic.
