I am getting ready to change the oil on a 2012 kia sorento with the 2.4L inline-4. It has about 150k miles and my friend who drives it goes up and down a mountain everyday. Engine was rebuilt 20k miles ago. The manual recommends 5w20 OR 5w30 for all temps. I am thinking of getting castrol edge EP and a fram ultra for a 10k OCI. This OCI will extend into the summer months this year. Are there any benefits or downsides to using 5w30 instead of 5w20? Would it run hotter or take longer to get up to operating temp?
