I noticed there aren't many tutorials on the web on how to change the engine oil for the Nissan 350z, so here's how I do it, please follow the instructions diligently as I am not liable for damage or personal injury.
I use 5 Litres of Fully Synthetic 5W30 ACDelco + Cooper Oil Filter, although OEM one claims to have a relief valve apparently. Oil = Â£16 Filter = Â£5
Step 1: Warm up your vehicle, dirty oil comes out faster and easier when the oil is hot.
Step 2: Loosen oil filter cap and pull out the oil dip stick, this will also speed up the flowing process.
Step 3: Jack up your car using an appropriate jack and because the 350z is a very low car, its imperative that you use a jackstand and a piece of wood to block one of the wheels so the car doesn't roll off.
Step 4: Remove plastic panel that covers the bottom of the engine which is held down by screws and plastic clips.
Step 5: Remove the drain bolt and let the oil drain out completely in a oil pan.
Step 6: Install the drain bolt and make sure you use a copper drain plug gasket. (Nissan uses a special copper drain plug that is around 2 mm thick, when you tighten the bolt, the washer thins out. You can get these at your Nissan Parts Counter for about Â£1 each. Tighten drain bolt at 29.4-39.2 NM or 22-28 FT-LB using a torque wrench.
Step 7: Remove oil filter using oil filter removal tool. (see step3.jpg) You can buy the one from Nissan Part no. KV10115801, its just a simple oil filter wrench that fits perfectly on the oil filter. When installing the new filter, use your fingers and rub some new oil on the filters o-ring.Tighten the oil filter.
Step 8 : Wipe off visible oil on the filter and drain bolt area. Re-install plastic cover
Step 9 : Remove Jacks, Wood blocks and Jackstands.
Step 10 : Pour in 4.7 Litres of new engine oil (use a funnel it helps), turn on the car and let it run for a couple minutes. Check for leaks, add additional oil until the oil level is centered (between low and high) on the dipstick.
