I use my 99 sentra for gettin to and from work 35 miles ea way.
I currently have 130,000 on the engine and it is defently loosing some oomph.
I dont belive the timing chain as ever been replaced nor the tranny fluid replaced. I run Mobil 1 full syn in the engine and after 3000 miles still looking preaty clean can still see the metal threw the oil.
should the timing chain be replaced now I does it need to? I have been told chains dont need replacing untill they rattle and its not making any noise on start up. also what tranny fluid do you guys recomend in the auto
