First oil change I did on my own, 19 years old, my '02 Altima 2.5 that had 103k miles at the time in November 2010. I used PYB 5W30 and a Mobil 1 filter. Before that I had never done an oil change before besides helping my dad with the Cummins in my sig. I've done literally hundreds of oil changes for family and friends since, in the past 8 years.
