best for full fluid change
 

Hi all,
I asked this on the elcova forum, but...
1) i didnt get any response
2) i cant get on elcova about 1/2 the time

I am wondering what is the best fluids to get for a full fluid change.
I dont mean brand names, I mean like types of (ie. dot3 vs dot4, and so on)
Also, when I say full fluid, I mean oil, tranny, diffs, brakes, etc etc etc.

I have 107k and I do alot of highway miles so I want to keep it up on the best

Thanks
