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!
