Whatever you use, make sure you've got a GL4 oil for your gearbox and a GL5 for the diff. Personally I like Redline MT90 as it stands up to a lot of track days, but can be a bit thick in Winter. MTL is good for street-use. Didn't rate the Nulon stuff and currently running Castrol Syntrans, which isn't too bad but I haven't been using it for very long.

I have a 1.5-way diff so I use Motul competition oil, 75w130 weight or something.

I have change my Manual box oil recently. You can try Motul Gear 300. It can be used for both box. I was recommended Royal Purple for my gearbox, by this autobarn guy, as they ran out of Motul. I can say not totally happy with the purple. It's works ok after a few km during early morning cold start, but during the 1st set of traffic lights I pull up. Always have difficulty put it into 1st gear, sometimes 2nd gear too. After the oil has warm up, then It do feels very smooth. I have yet to change my Diff oil, so I guess you can try some other and we'll see how. The purple does seems to be much thicker than the old oil I took out. Quite a lot of metal filing can be seen from my old oil, but maybe the oil got so old that it has thin out. It's recommended by nissan to putting 75W-80 for gearbox and 80W-90 for Diff. The Royal Purple and Motul are both 75W-90.

Thanks for the fast reply guys,

i changed the motor oil as soon as i got the car few weeks ago but never even thought of doing diff and trans till i spoke with a fellow SAUer last friday. I drive maybe 10kms per day if that, pretty clean run with barely any stop/start but id rather be safe then sorry :)

Now regardless if your a Nulon fan or not,

this is a good guide to use: http://www.datateck.com.au/lube/NulonAus/default.asp

Just specify car, nissan, then i went for 350z and it lists in categories ie motor, trans etc which oil you should use.

      Do not ever trust ChatGPT with anything math related. They can't do math. They have no idea what it is. With enough data we can fit a decent equation in Excel, or if the available fits in Excel aren't good enough, a Matlab clone.

      You could check/calibrate that with a thermometer, we have long glass thermometers at work which go from -10 to +150°c, they are pretty cheap too I believe,  as monkey fisted soldiers tend to break them, and getting new ones don't seem to send red flags to the people that hold the purse strings Edit: after a google they apparently cost about $80, but, digital ones seem to be much cheaper at around $40

      I should have prefaced all of this with "I'd really like to not pull anything out of the car for this"

      Me, I would happly spend some more coin on better tyres for my street car  Will they work, yes, of course, but why substitute some dry grip/braking distance, and wet weather grip/braking distance on what is really old tech to save some coin on your "precious" street car In the end it might not be you that farks up, it's the thousands of other idiots on the street that you need to worry about  For a street car that gets some "fun time", I have found that a quality tyre that can handle dry, wet, cold (Canberra gets pretty cold) and hot conditions, which may costs a little more, is great insurance  From my experience with them (driving around Goulburn in the winter) the RE003's are pretty poor in cold and/or wet conditions on the street If RS4's didn't hate gripping in the cold I would be running them always on the street,  great in the dry, OK in the wet, but, they do hate the cold, with a passion, I run PS5's year round now, basically, I've found the PS5 to be a great year round street tyre for all conditions, they last well, and are mid range pricing wise TL;DR. Tyre choice is probably like what brand and grade oil you should use, ask 10 people, and get 10 different answers... LOL
