best oil for 2010 nismo Z?

VCuomo

Care to elaborate? I tried not be in depth in oder to avoid another oil thread as a search was already suggested...maybe some actual advice as opposed to a facepalm might help the OP?

The oil doesn't have to be synthetic. There have been many threads with tons of posts about what types of oil can be used in the Z - that's why I used the facepalm. The key is to use an API or ILSAC approved oil with the correct viscosity for the vehicle's operating conditions.

BTW, Nissan's ester oil is not a synthetic oil (it's supposedly a dino oil with ester additives).

This is the reason why so many threads exist on one topic... everybody here is an engineer. I am hoping no one comes across this thread looking for basic information as it looks like EVERYONE knows API or ILSAC approved oils are key for optimal performance in the 370Z. Thanks for the info.

All oils are not created equal. You have to take into account their shear resistance, how their weights and protective properties are affected by temperatures and high RPM applications, and their detergent properties. There are some crappy synthetic oils out there that can be so bad that they thin out at operating temperature or at high rpms and the molecules start shearing which is when your engine will not be protected adequately.

A quality synthetic oil will resist shearing, have longer life, will not be affected by the demands of high rpm, and will be developed to protect the engines at any condition.
