Just bought a high mileage Nissan 4 cylinder 4X4.
Everything is OK (as far as known) with the 4WD driveline, except for some slop in the shafts coming out of the transfer case. No leaks of any consequence.
Manual calls for GL-4 in the trans...GL-5 in the transfer case and diffs.
Questions or opinions...
* can I use GL-5 in the trans too...and why not? Can I find GL-4?
* wanted to use Mobil 1 synth...but they only want $9 per qt now....so I might want to use Valvoline semi-synth or regular gear oil...and change it out more often.
* with the dino gear oil...I'd like to use a good additive...prefer moly...but maybe Militec or similar?
Maybe Lubegard's gear oil additive?
* talking about 9 quarts overall
** wanting better mileage and duriability...on and off road...
Any help appreciated.....
