Alan, thx for the correction, you are absolutely right! So using 20W50 Synthetic in my 2005 should be just fine. I can't figure out where all this varying info comes from but I will call all the dealers in my area and see what they say. In the mean time, 75W140 Synthetic is going in the rear and 20W50 in the engine now that I have about 10,500 on it. If anyone would like to add to this discussion, please do so.
