I used to be an avid Shell user, but after trying Liquid Moly oil as a friend's recommendation, I won't go back to Shell. I had a hard time finding a great motor oil to use on my 2022 Audi RS4 that could handle the high demands of a motor notorious for burning oil. After the oil change, I drove around town for a couple of days without any spirited driving, just to make sure everything was properly lubricated. I checked the oil every time I stopped, nice that my oil was still full and in great condition. The transition from Shell to Liquid Moli was made at 133 thousand km, after washing the engine. The engine began to run quieter, maslozhor significantly decreased.
