One of my older cars (2006) did trip the check engine light for oil changes IIRC. I could be mistaken though.

Regardless, checking the codes is always a good idea, never assume.

Don’t listen to the parts store guys, they are there to sell you parts.

Absolutely. But pulling the code is absolutely the first step to figuring out what went wrong. Sometimes it directly indicates the issue, and sometimes it trips due to another issue. I take the code, do a little research, and if I’m not confident in my own diagnosis (or it’ll be a costly repair), I’ll take it to a mechanic.

But don’t just sit on the check engine light. Figure out what it is and address it. In my state, you can’t pass emissions testing w/o having a clear check engine light (and yes, they check if you cleared it) or apply for an exemption, so we at least need to take care of it by then.
