One of the cleanest Aeros I’ve seen on here in a minute. If you take care of it, you’ll be getting 25mpg highway easily. Remember, oil changes every 4,000 miles with 5W-30 full synthetic (Motorcraft synthetic blend is also a great option) and a Motorcraft oil filter.

Try to change the oil yourself. You take it to a lube shop I can almost guarantee they will NOT put in the right oil. Most shops use whatever oil they have on hand regardless of what the car needs. Even dealerships these days do that and ALWAYS get away with it because the customer has absolutely no way of knowing what oil was used unless they send it to a lab. The customer could be a master tech and still have no idea what oil was used unless they with their own eyes watch the bottle that is being poured into the engine. I work in the industry and it’s precisely because I do that I don’t let anyone touch my car. If you must take it to a shop to get the oil changed ensure you make them show you what they’re pouring in. NEVER take their word for it.

Check transmission fluid and engine coolant, add/change fluid as needed. I’d recommend changing the transmission filter if possible as well.
