Hi all,
After 14 months of waiting for my '23 CT5-V Blackwing and 2 months to break it in over 1,500 miles, I took it to my Cadillac dealer on Monday for its first oil change. 20 miles later (mostly highway) I found out that they only used ~5.5qts to refill rather than the 9-10 it is supposed to take. It literally took 4.5qts added to get oil level to the top of the dipstick operating range.
Obviously I am livid and sick to my stomach, and trying to get the dealer to cover an extended warranty from GM. However even if I succeed, I am worried about any long-term damage or added wear and tear. How concerned should I be about that? Someone on another forum mentioned that 5.5qts should be enough to keep it lubricated, and that the extra capacity beyond that is more for thermal capacity when tracking - sort of makes some sense to me but that may be overly optimistic. It's a wet sump in the Blackwing, btw.
The car exhibited no ill effects, and I didn't really get on the gas too much on that trip home (no revs above 4.5k). I keep an eye on oil temp in general and it didn't seem notably off, and while I didn't specifically monitor the oil pressure on that drive, that readout is right beneath the oil temp in the cluster so I feel like I would've noticed if pressure was way low.
How worried should I be? This is a car I intend(ed?) to keep for 10, 15, heck maybe 20 years so to have this happen at this juncture makes me way to cry.
