Took this sample ice cold. no oil added, headgasket changed at 55k miles. when we took this car to get the headgasket changed out, the work order said changed oil. however my supertech oil filter was still on there which possibly means they didn't do the work. I bet they just tossed some coolant tabs in there and never changed the headgasket. My newphew turns 16 in October and my sister talked about buying him a new Nissan Sentra like my dad's car. She even talked about trading her tahoe in for a pathfinder. not while I'm alive and breathing. This is our first Nissan product in the immediate family.
