I called the dealership and they quoted me $300 for a CVT oil change. F that. F that so hard. I'm gunna do it myself. I need Nissan ns2 oil, 5 quarts. The transmission takes 4.5 quarts. What else am I missing? I feel like it's such an easy thing to do but I feel like I'm missing something for the dealership to charge $300. Also, I'm doing my own oil changes. What engine oil viscosity should I use? 5W-30?
