TIL that synthetic oil changes should happen every 7500 miles (though my owner's manual says 5k). Went to a Popular Oil Change place today and the sticker they gave me was 3k (which is correct for conventional oil). Synthetic oil is expensive. They're actively ripping you off if you go by the sticker mileage. Question everything.
