Hey all. I brought home a 2025 1LS with the LS convenience pkg and driver confidence pkg. Currently have 1560 miles on it. Does the engine get louder or am I just hearing things? I have ran 87 octane in it except for one instance when the take was basically on E and I filled it with E85. After the crappy mpg on E85 decided to stick with 87 octane.

Welcome to the forums! Don't really think it becomes louder but never used E85. You do get less mpg as you stated but you get a little more HP from it if I'm not mistaken.
Welcome. If you are wanting to make it last, make sure you maintain it. For instance have you changed the oil yet? The first oil change can be the most important one and should be done early. When an engine is broken in there are tons of very fine metallic particles that get into the oil. I drained my oil at 500 miles but kept the filter and then did a full change(oil and filter) at 2000. If you are still on the original oil, don't panic. If anything I am being overly cautious BUT don't let it go till the car tells you as that is way too long for the first change. Even later the factory interval is a bit longer than it should be.
