2008 Infiniti G35 Q&A
2008 Infiniti G35 Question: what service should be done @ 50,000 miles? tune ups? belt changes?
If you have about 50,000 miles just change the spark plugs and air filters and see what happens. If you are due for an oil change then do that too. Also, can't hurt to change the fuel filter at this time as well. Belts should be okay but, apply belt conditioner spray to them so they don't start drying out and cracking. - csubak30
