So my car is almost reaching 105k and thats around the time that i need to get an oil change. Now as far as i know this car has never been serviced. I could be wrong.

What is the best step to take to keep my car running at its best?

 

get a tuneup from any local shop have them check everything out. even taking it to nissan for the tuneup might be a good idea because the rear plugs are hard to get to.

 

What would that replace?

 

Oil Change
Coolant Flush
Seafoam
PCV replacement
In cabin filter replacement
Transmission fluid change
Clean throttle body
Chevron Techron
Spark Plugs
Air filter

 

In a 5.5 they are, not in a 5th

 

read the schedule in your owners manual

 

I'm like 10 miles away from hitting 105k, and that's the point where I need an oil change too!
