Hey all,

After checking the level I'd like to add some gear oil to my 8 3/4" 3.23:1 Sure-Grip rear end. I purchased a quart of Valvoline 75W-90 Gear Oil. On the label it says "Limited Slip". Does this mean I do not need any additive for the sure-grip? The 3 guys at the Auto-Zone each had a differing opinion. Attached is the label from the bottle. Any guidance is, as always, appreciated.
