I would just do it yourself and ask where to send the letter proving the oil you just changed on your car. 40 miles round trip plus waiting at a dealer is something I personally don't have the time for.
I agree but either way is a PITA.If you do start doing it on your own, take pics of the oil life monitor and mileage, photocopy receipt of both oil and filter. I go the extra mile and take a pic of the actual oil and filter before changing. I agree with above and the dealer will probably want you to bring it in to keep the warranty. BS in my opinion... oil changes aren't rocket science. Just keep documentation to protect yourself. Good luck.
I think if you have a moderate to major issue with your cruze having a positive relationship with dealer may be beneficial when you need them to be your advocate. My dealer will change my oil and let me bring oil in for $20. Especially when it’s cold outside, I will let them do it. Yesterday I worked 15.5 hours, I do t always want to fuss with doing an oil change.The flip side of having the dealership change your oil is you get to see how they handle the simple, routine stuff a car needs. You can also talk to the techs and service writers and build a relationship with them. These two simple things can come in real handy when you have a problem that you can't fix yourself.
