This is my second time using this product so their is no explanation it's freaking awesome
It's really good with increase if performance and Engine speed as well..
My car got smoother and a slight increase in acceleration too. Must have soo much better than renault oil.
Best oil for vw tdi. Switched from liqui moly toptec to meguin this time. I don't observe much difference as both are essentially the same oils. But it is definitely better than castrol. Gives better NVH levels and smoothness. Fast shipment and quality packing.
Very good engine oil, used in my 2016 polo. Very smooth and good performance
