I have a bumper to bumper warranty with Nissan for 10 yrs 100,000 miles. Im tired of going to have my oil changed by brain dead grease monkeys. Last trip to get oil changed was a joke. Checked the dip stick and just had enough oil in the motor to keep the low oil light off! I can change it myself, that's no problem, but i dont want to screw up any thing with documenting my oil changes. So question is, if I start to do my oil my self what will Nissan accept for documentation that oil changes (by me)????
