everything you have done to it including oil changes and regular service,this is only needed in case their is warranty work that needs to be done to it,then they cant say you didn't maintenance it well,but id keep track of everything i did,this way they cant dispute it ,and believe me they will try ,some dealers wont even want to do warranty work on it unless you bought it from them,so keep notes on all you do to it with dates and what was done,good luck with it.
