Welcome to the Cadillac V-Series Forums!

What did you do to your Blackwing today?

It's always a concern to me if they use the right oil. Two times ago, there was some confusion about the "right oil". The service guy came out later and apologized and said he's new and not overly familiar with Blackwings. Last time we were good. No issues, no questions.

I always Google the correct part number before I go (as GM changes P/N's often) and double check before I leave. I figure if the P/N is right, it's on them if something happens. I like to ass-u-me the tech uses the right stuff. I mean, what's he care? He gets paid either way. I even thought about going to the local Chevy store to see if they have a "Corvette" guy and if they'd change it.

You can always ask them to hold onto the empty quart bottles to show you when you pick up the vehicle. Add it as a special request when you drop off the vehicle for service. I don't know they'll honor the request but can't hurt to ask.

When we were at the Cadillac hospitality tent at the Detroit Indy race a few years ago, the folks were there from Mobile 1 to do a tech talk. The manager of the group openly told everyone that they should ask to see the quart of oil before it goes into the car, like a fine bottle of wine. He said that the dealership that he used was sour about it at first, but got over it. It was interesting to hear the actual Mobile 1 guy say that this was necessary (sort of vindication of OCD).

Nonetheless, I did as told during the first oil change at the dealership. To hedge my bet, I asked the scheduler to note that I was going to do so when I made the appointment. Lo and behold, they brought out the quart of the Euro version. After reviewing the owners manual (pg 300 “…DexosR…”), they had to order the correct stuff in from another dealership. Afterwards, my receipt had the correct p/n listed on it.
 
I normally do my own oil changes and send outgoing oil samples in for documentation and to monitor engine health. It may be a bit overboard but after hearing warranty horror stories with Stellantis I started using this method.
 
The reason why my BW5 is and will remain in storage until spring.
