Hey, does the amount of oil in the differential really make a diffrence? I only ask this because I am looking to upgrade my cover and have looked at all the covers and found most have around 5 quart capacity compared to the 4 quart of the stock. But the Mag hytec claims to hold 8 QUARTS ! Anyone comment on this? thanks
