Chevron Techron High Mileage Fuel System Cleaner, 12 oz, Pack of 1

Nice and clean aesthetic, Love it. Replace that PCV valve and inspect the PCV hose to make sure it's not cracked (if it's cracked, obviously replace it too). The PCV is CHEAP and easy to replace. Use fuel system cleaner for two back-to-back fuel tank fill-ups to make sure your fuel injectors are clean and spraying good patterns. Again, this is relatively cheap to do.
