WRONG OIL USED FOR TURBO
Why would they use the wrong oil?
Incompetent, don't care, don't have the right stuff, wanted to charge more for the syn....pick your poison. My experiences would lean towards incompetent.

Could this damage the turbo/engine?

How would you or anyone else know w/o a teardown to have a look see at the internals? If you weren't constantly hammering on the engine, I wouldn't think a one time mistake would be an issue, but, the stuff they put in is water thin. Continued use of the wrong oil however, would be a different story.

Will it affect the warranty?

It certainly could give Mazda an excuse not to cover any engine lube related damage should you need the warranty in the future. Suzuki dealers would ask for all OC receipts before they did a teardown if they suspected internal issues. If you didn't produce receipts showing regular and proper OCIs, they wouldn't even go any further until you agreed that you were paying for the work. (dealers get burned all the time by the manufacturers for warranty work payment). If OCI receipts checked out, dealer would tear it down after getting approval from ASMC. They'd locate the issue and then contact ASMC again with the findings and for approval to continue at ASMC's expense. Regardless, if ASMC denied the claim, you were on your own negotiating (or fighting) w/ the dealer that did the work over who was paying for the teardown (already done), the repair, and reassembly. Now you're in to the 'how good is your relationship w/ your dealer' phase of negotiations and how forthright are they as a business. I'd certainly hold on to that receipt just in case. Depending upon how the
Service Manager reacts to your asking why they used the wrong oil, you then may want to consider contacting Mazda directly and opening a case directly w/ them yourself so they are aware that one of their dealers used the wrong oil in their engine that is still under their factory warranty.
