Review on LIQUI MOLY Hydro-Stossel-Additiv, 0.3 L by Petar Atanasov-robi ᠌

The car has 185,000 km. Helps with the knock of hydraulic lifters. The service advised how to try as an option, and if it doesn’t help, then change the hydraulics. Filled in both fresh oil and used oil. But fresh is better, as they say. The clatter when you press the gas disappeared and at the start in the morning. This additive increases the viscosity and is excellent for pouring in the summer.
