Review on 5W-30SN/GF-5 by Ada Dudek

Great oil at a very reasonable price! I take not the first time, I am extremely satisfied. Comparing it with Helix Ultra, of the same viscosity, I can say that the engine runs quieter with this oil, throughout the entire period of operation, until the change. Before the price increase, Shell cost a little more, now, the difference is 2 times. Does not fade from the word at all. Extremely happy with the oil. Auto Kia Rio 4 1.6 2022 Guards
