Need help now my walmart has every brand 0w-20 I like and I'm changing my 2014 altima sl 4cyl oil tomorrow. What's worse is all the same price. Mobil1 advance fuel, mobil1 ep, Carstrol edge, all $25.17 now currently run afe with no complaints but if ep is same price and let's me run longer oci why not right? But it doesn't specify fuel economy either like afe does? And last the Carstrol I noticed a lot of users here really liked some favored so I'm torn. I know they are all great but on paper since they cost the same is one better spec wise and or would one be more suitable for my motor? Help appreciated.
