conventional (non-synthetic) oil
Just curious....this is from the owners manual. I notice a lot of you are putting synthetic diff oil in. Why would nissan recommend this and why are most all of you ignoring it....just asking because i want to do the right thing for my vehicle. What would it hurt to put a synthetic oil ( im asking because this is what i have available in my garage) instead of convention in my Z sport?
Thanks in advance!

I would disregard this manufacturers recommendation as any quality synthetic API GL-5 differential fluid will suffice for our application. A 75W90 gear oil is a suitable replacement for a differential calling for an 80W90 or SAE 90 gear oil. I recommend 75W90 synthetic Redline gear oil or equivalent.
