Oil recommendation for light track use-but hot weather.

Volk Z

Amsoil signtature series. 5W30. You asked about weight the starting weight is just the beginning weight the 2nd number is what it goes to after its warmed up so the weight would be the recommended oil 5w30 unless you have a turbo on there then a heavier weight may be needed (I.e 5w40)
I run the K&N oil filter it has a hex head so when you take it off its super easy. I coupled that with a magnetic add on that clips to the filter to keep all metal shavings in the filter and a Greddy magnetic drain plug.

Amsoil is the first in synthetics and I use in all my cars engines, transmissions and differentials. Google amsoil vs *any oil brand* and you will see it annihilates the competition.

As for the oil cooler, I have a 2013 and its great for street use BUT I'm not sure if it could sustain heavy tracking so you could run another cooler on top of it to be safe if you are worried.

Lastly, I used to live in Rancho Santa Margarita right next to Mission Viejo! My Dad still lives there! Small world

while the "series" might change, this has been a good rule of thumb for awhile. from best to worst starting points of oils...(not all shown). oil reports will tell what "annihilates" the competition.

The best base stock is Polyol-ester (Redline & Motul)

Next best is Di-ester (Royal Purple, Amsoil, Neo)

Next is Polyolefin polyamine (Mobil 1)

Next is Hydrocracked (Syntec, Valvoline)

And finally, regular dyno oils.

Motul has a 0w40 that is specifically recommended for the 370z. It's about $60 for a 5 liter jug... (5.1 quarts) Just enough for a complete oil change (if you don't have an oil cooler). I'm trying it this weekend. Motul makes all of Nissans oil. Including the super duper Estér Oil.

ok im a little confuse now after reading all this thread hahaha!! I use Mobil1 synthetic oil 5w30 Extended Performance since I buy my Z.... I would use Amsoil or even Motul but to find those oils here in Puerto Rico is very difficult Well I use my car as my Daily Driven and some sprinted or track days sometimes... My question is... If I change now to Mobil1 0w40 they are going to work better than the 5w30 that is the one recommended for Nissan to our engines? the temps over here are arround 70+ to 95 degrees and in summer on a very hot day you can see temps on 100 degrees

Any help or recommendation are welcome... BTW the oil cooler are on my wish list as soon my new damn wheels arrive someday

Thanks!

Rusty

I run the Mobil 0W-40.No problems.
