... recently purchased a used 2011 Impala from a dealer, 3.5L V-6 LZE, 52448 miles at delivery
... unknown oil and filter, OLI is now at 49% after ~ 3000 miles
... naturally manual calls for 5W-30 dexos 1 oil, and O'Reilly locally has AC Delco dexos 1 oil for ~ $6 a quart
So here is the question ... I am nostalgic as [censored] ... I would really like to use a "classic" oil, perhaps Trop Artic, Gulf, Sinclair, etc ... anyone see a problem with these oils??? I don't. To me the VOA's look fine. I drive 80 miles round trip daily, highway miles. And plan on a 5000 mile OCI
