Dealer keeps using 0W-20 oil instead of 0W-16
My 2024 Camry SE specifically states that OW-16 oil should be used. 6 months ago they used 0W-20 because supposedly they did not have the one I needed. The service tech stated that this would be done only once. The manual also states 0W-20 may be used once if 0W-16 is not available.
They have done this twice already, and I am sure they did it before but I wasn't paying attention. Should I make a big deal out of this or let it go. This is my first new car that I've ever bought and I plan to keep it for a long time so don't want the engine to have problems
