Default High pitched noise

After the second tank of 90 oct + semi sinthetic oil I prepared a 98 oct + semi sinthetic oil mix
98 oct pump gas in my country has a strange smell, not exactly good old gasoline
Used it today going to work, and coming home the engine started a high piched noise, like something out of oil (or am I just paranoid?)
Barely audible with the engine running
Engine on and clutch pulled there is noise
Engine off and clutch pulled there is no noise
I asume it comes from the engine
Is it normal?
Is my engine dead? (hope not)
Thanks in advance
