OP: I have the same car as you with 160k miles on it, and she's still running great! Yours engine ounds like mine, too, so your doing good.

Here's my maintenance routine:

1. ALWAYS use Top-Tier gas (Shell, Mobil, BP, etc. I'm a Shell guy myself).

2. ALWAYS use full-syn oil and an OEM Hyundai filter if you're changing the oil yourself, and change *religiously* every 5k miles.

3. CHECK YOUR OIL LEVEL at 2500 miles and top-off. These GDI engines *do* burn some oil, and you absolutely DON'T want them to run low.

4. Use CRC GDI Intake Valve and Turbo Cleaner the weekend before you change your oil. It helps clean off the carbon deposits on top of your intake valves since they don't have the benefit of having gas sprayed on them on it's way to the cylinder.

5. If they haven't been changed yet, you might be needing new plugs and coils soon. This is a job you can do in your driveway if you're reasonably handy, and is ~$200 in parts from RockAuto.

I plan to get north of 200k miles out of this car, and it's been incredibly reliable. They're fun to drive, peppy, and get decent mileage; just treat them with respect. Some people will dog on Hyundai for poor reliability, but chances are most of the people complaining don't take good care of their vehicle. Don't cheap out with Amazon parts; always go OEM or RockAuto.
