300ZX Oil Change - Restore & Protect

With the full suspension refresh wrapped up and fresh fluids throughout the drivetrain, the 300ZX convertible was overdue for an oil change. The factory fill was long gone from the other services, but I hadn't done a proper oil and filter change yet, so it was time.



I decided to switch things up this time and go with Valvoline Restore & Protect Full Synthetic 5W-30 instead of my usual Mobil 1. Valvoline's Restore & Protect line is formulated for higher-mileage and older engines - figured it was a good fit for a 33-year-old VG30DE with only 39k on the clock. Low miles, but age takes its toll on seals and gaskets. This Z also has a bit of lifter noise - something the VG30DE is known for - and I'm hoping the Restore & Protect can help keep those tiny hydraulic lifter orifices clear.


I paired it with a Nissan OEM oil filter (15208-65Y0A) - no reason to get creative with the filter when the factory part is still readily available. Drained the old oil, swapped the filter, and filled her back up. Simple and clean.


Odometer sitting at 39,020. She's not racking up the miles, but she's getting the attention she deserves.
