Looks like a nice oil other then the ash is at 1%... 0.8% or less is the sweet spot. Too bad, I expect ignorance from someone off the street but from the service department of the company selling the product...unacceptable under any circumstance. If you're not 100% confident, ask someone else who is or take the time to make a call/look something up....Like we've all doneSo I went in for my 7500 mile oil change and the dealer recommended Mobil Delvac 1 ESP as the synthetic oil for my car.
They were very understanding and used my Mobil 1 ESP 5w30. Seems the education still isn't getting through.
I was also told by one employee that I would void my warranty if I used a non-Dexos 2 oil. Not really confidence inspiring but they were willing to listen to my concerns.
I hope they get this figured out. Officially there is no listed synthetic oil for the Cruze in the GM parts manual.
