This is a report from a friends Traverse. They didn't have time to take it to the dealer to get the oil changed so they had me do it. This is the AC/Delco dexos oil that the dealer has been installing in their Traverse. This oil has 5k miles on it and had the AC PF 63 oil filter on it. The oil level was also low by about a qt. I don't know anything else about the vehicle other than they drive it a ton and it does a lot of country back road running since they live way out in the country. This is also one of the Wix tests that I got off Amazon for $7 a while back. I picked up 5 of them at the time. My biggest complaint is that it takes forever to get the results. They keep telling me that the sample didn't make it to the lab when I call, but I know it did since I sent it Priority USPS and from here to Atlanta is only 400 miles.
