Can I use 92 octane gas in my Audi A4 2.0 TFSI engine?

I recently purchased a 2018 Audi A4 with a 2.0 TFSI engine and I'm not sure if I can use 92 octane gas in it. Can someone confirm if it's safe to do so and if it will affect performance? Thanks.

Yes, you can safely use 92 octane gas in your Audi A4 with a 2.0 TFSI engine. In fact, it is recommended to use at least 91 octane for optimal performance and fuel efficiency. Using lower octane can cause knocking and potentially damage your engine.
