If you want to replace a genuine product, try to go to a larger 4S store to replace it. The price of Mobil 1 is about more than 100 to more than 200 per liter. I used it after my previous car was out of warranty. I have exchanged Mobil 1 for expensive and cheap ones, but later I did not dare to change it anymore. There were too many fakes, which cost about 6,000 to 7,000 yuan, and I had to replace it every time around 7,000 to 8,000 yuan. Later, I was afraid of buying fake ones. The oil damaged the engine, so I replaced it with German GT oil. The main thing I liked about this oil was that it was not fake, and it can run 13,000 kilometers once replaced. The price/performance ratio is really good.
