yeah that is my major concern. I research A LOT before I buy every car I own. Has Nissan come out and said the safe range for the oil temperature (what is normal and what is considered high). Thanks for the help by the way. I just drove a 370z for the first time two days ago and LOVED it. I felt like I was in a rocket when I pressed the gas

I've had my '09 Z for 2.5 years now and the oil temp has never been an issue. I never track my car, just drive it in all kinds of settings, sometimes with spirit. The oil temp has never risen to the level of concern. Unless you track your car, I consider the whole issue overblown and actually a tempest in a teapot. Other than a minor adjustment to my ambient temperature sensor, my car has been perfect since showroom---no problems at all.

For just spirited driving you should be fine without getting an oil cooler. If you take it to the track you will need one.

The oil issue is only for those concerned with the track. I've done many spirited driving sessions on mountain roads and while Oil rose to about 240, it was totally fine. For quick DDing there's no issues.

If you're headed to the track you'll want one. Not a issue big enough to not buy an amazing car.

Go test drive a Z!

You only need a oil cooler if you plan to track your car. For street driving there is no need for it. I had my share of spirited driving and my car never went into limp mode.

I am glad the community has learned about the oil cooler and properly giving advice about it! there was just too much hysteria about oil temp issues and daily driving!

The Z does not need one unless you track your car case point!

Happy Driving!

I've been saying this for three years. Talk about being flamed when it all started. Some people still can't let go of the "260F oil temp will melt your bearings." Ain't so anymore with today's oil formulations.

Amen brotha! Some people jus can't evolve with the times. Higher performing engines = higher temperatures = normal! Much better synthetic oils with higher temperature tolerances. 260 ain't nothing!

For people who have installed oil coolers, did you do the install yourself or take it to a shop? How much do shops typically charge?
