I'd like to only buy one grade of oil for my four vehicles, two take 5w-20 and two take 5w-30. Our newest vehicle uses 5w-30 Dexos oil (2014 Chevy Sonic), so would it be wise to switch to ST 5w-30 Dexos synthetic for all of them?
Currently none of my vehicles except the Sonic run synthetic oil.
Thanks
