Hey, I'm currently using Amsoil Synthetic 5W-30, I'm about to go on a road trip tomorrow and need to change my oil anyway. I was wondering With the Summer heat should I be using something other than 5W-30 I have an 04 Ram 5.7 Hemi. I'm going to the desert area of Oregon and the temps have been up in the 95+ range and my truck is used to driving in Washington weather.
Any Help would be most appreciated, like I said I leave tomorrow so hopefully I can get some help before then
Thank you
