Review on Synthetic Engine Oil LIQUI MOLY Top Tec 4600 5W-30, 5 l by Adam Kardasz ᠌

Opel Astra H 2022 Z16XER. There was a problem with the phase shifter pulleys. The petals that open and close the access of oil over time began to knock and made a sound like a diesel engine. At that moment, the original GM oil was poured and the car's mileage was about 110k-120k. The pulleys were replaced and switched to this oil (Liqui Moly Top Tec 4600 5W-30). And they began to fill in Shell 95 V-power (with detergent additives). After 70 thousand km, the "head" of the cylinder block was removed. There was a little dirt in the cracks, but in general everything was "virgin". The service explained that for 180k-190k km the condition is good. Now the mileage is 245k. There are no pulley problems. Oil change every 6-8 thousand with original oil filter or MANN-FILTER company. I continue to pour Shell 95 V-power. I use DENSO IK16 iridium spark plugs. Everything is okay.
