My thoughts exactly. I was just going to post this!!!! I was told by my dealer that 75-140 would be a GREAT choice for use in my 2004. 5 4x2 3. 73. I explained that I do lots of towing, and he said that would be a good weight to use. A friend of mine just had his truck serviced by the dealer themselves and that is the weight they put in it! I am hoping more people chime in here on this one... I want opinions too!! Please post away!!! AMSOIL also confirmed that the 140 would be best!! I had rear end rebuilt at 2200 miles and would like to keep it working nicely. I have a small noise now, and hoping the AMSOIL 140 will take care of that last little bit of it!!
