I have a new 05 Ram 3.7 v6 and live in texas.My question is on the oil cap it says 5w30 and have a 7/70,000 warranty on the truck and was wandering could I use the 0w30 GC and still be safe with the warranty? And would it hold up to the Texas heat in the summer months? I'm thinking about useing this oil.I looked at a az here and they had a good supply of gc.Thanks
