I have a 2013 verano premium that needs an oil change. Should I get full or blended synthetic dexos1 oil? Does oil filter matter as long as it fits? Do I need any special tools like a new filter wrench etc.?
3,500 mile oil changes are a waste of money, Todays oils are much better than back in the 50's and 60's. Any oil that meets the Dexos1 Gen 2 spec will make the 7000 - 7500 mile avg of the OLM standing on its head.
