Im a new owner, and Im eventually trying to do all the fluids.

Its nice to know you have fresh fluid and the piece of mind that goes with it.

air filter
oil/filter change
trans fluid - honda mtf II
Diff fluid
coolant/check hoses/etc
clutch fluid
check tire pressure,etc.
check battery levels -top it up if need be
check spark plug condition
check belts for cracks/fraying/etc

theres really not too much that this car needs aside from fluids

 

Bro, replace all your fluids look at your brake pads if worn replace them.

The only thing i wouldnt run to replac eif it test good is your coolant.

 

All fluids unless you're certain that the previous owner took care of them (from what you've stated it doesn't sound like you can). Check other wear items and replace as needed.

As someone has already stated there's no telling (probably not much except for tranny and diff) but you want a known point of reference for future maintenance. Unless you're going to assume that all the fluids were fresh at the time of purchase (I seriously doubt it) and start the counter for everything at zero.

Replace all the fluids. "Feel" is of very limited use in these cases.
