Message	Very first time I changed the diff oil years ago,I tried RP 75W140 (someone had recommended it) and it caused a lot of drag and made the car sluggish. Drained and refilled with Amsoil AGL 80W90 and it felt night and day better. That fill was in the diff for around 60k miles or so. This time I went with Severe Gear 75W110. Only reason I asked about the Nissan oil was because of the Nissan TSB I saw. There's also a TSB stating to use 5W30 in all Nissan vehicles,but I'd never go with an oil that thin. Like I said,just curious about the rear diff TSB so I thought I'd ask here.
