Z Oil Change: Miles or Time?

370Z Purist

Typically a heavier weight oil is better suited for warmer or hot climates. A few people who drive in colder weather will convert to 0W-20 or 5W-20. I personally run 5W-30 since it's the recommendation, and since I typically warm the car and the oil to at least 180 until driving harder (keeping RPM under 3000, etc.)

There's no real need to change that oil immediately, since you're apparently in Israel and I'm guessing it stays pretty warm there.

Ester oil is nothing really special; it's any synthetic oil with an added ester base. In the Z it will reduce or eliminate valvetrain noise. It's also reputed to be more durable for higher performance engines, but proof is far and few in between.

I also noticed you started a new thread completely. The things that members have written there are good pieces of advice. Me, personally, I'd just wait 3k miles and change the oil back to 5W-30 using whatever oil you want. I'd stick with a synthetic, and this way, you don't waste your new Mobil 1 oil.
