2006, on my dads '06 Cummins which is now my truck. I was 15, didnt really know much about trucks, Ive come a very long way since then. diesel mechanic and diesel truck fanatic. i remember that oci because my dad told me to pull the plug and drain it, he walked away and went grab something. Well, when he came back, he was screaming cause I had unknowingly put a bucket too small under the pan, oil all over the driveway and my hair was completely covered in oil.(i was laying next to the bucket not paying attention) Lets just say i had to wash my hair with dawn soap about 5 times lol. first oci i did completely by myself was November 2010, on my '02 Altima, i used PYB 5W30 and a P1 filter. Dealer had changed it before, it took a 15 inch breaker bar to get the plug off and a screwdriver through the filter to get it off. I also faintly remember helping my dad change the oil in his '99 chevy back in 2002 or so. Ive probably done literally 500 oil changes since 2010.
