Greetings, I have a Grand Cherokee 3.6 L 2018 and I had issues before with finding the right oil since I live in a very very hot climate 131F (55C) in daylight. So considering that I had limited oil choices here I was struggling to choose the best, but now I found a place that sells Amsoil 0W-20 (which the manufacturer recommends). I really don't know anything about Amsoil and I heard that it's suitable for racing cars? The option that I have are the following: 1- Amsoil OE 0W-20 2- Mopar 0W-20 (I think Shell Helix provide them) 3- Mobil 1 5W-30 ESP Formula 4- Liqy Moly Special Tec LL 5W-20 This What the manual says: What do you think about Amsoil is it worth it??
