Hello... . I have a 2004. 5 Ram 2500 Limited Slip differential 4x2. 3. 73 Gears. What is the fluid capacity for the rear differential?? I was told 4 quarts by one dealer and 2. 5 quarts by a 2nd dealer and 3 quarts by a 3rd dealer! Maybe thats why most of us had them low on fluid from the very beginning. I do know there is a full line on my diff, But need to order the fluid and want to make sure I have enough... Can someone tell me how much it will take to be at the proper level???? I am switching to the AMSOIL 75-140 because I tow quite frequently, and sometimes in high heat areas... Is this a good choice?? Please respond as soon as you can. Thanks!

OH, After talking to all three dealers, one of them said I needed the LS additive, the other said I did not. I spoke to AMSOIL and they said I did NOT need the LS additive, as it was already incorporated into the formula... . what is your take on this???
