oil cooler

Oil coolers cause problems on the street. Now GM has an oil-cooler that uses the coolant to regulate oil temp. It lives by the oil-pan and has no fins, etc. It simply moves the coolant and oil near each other to keep them roughly the same temp.

A lot of Z06 owners from previous years are only hitting 135-155* on the highway oil-temp. My car runs 185-200* on the highway, depending on ambient temp.

So MUCH BETTER for the car.

I would suggest you take a note from GM who REMOVED an oil-cooler like the one you want to install and developed a different one that won't cause as much issue.

There's actually a lot about this I agree with.

A lot of Z owners jumped on the bandwagon, feeling the need to install an oil cooler on the car. It's simply not necessary for most users, and many street-driven cars won't get the oil up to proper operating temps with an oil cooler installed.

I've seen plenty of users bragging that their oil temps stay below 170 with their cooler. At that temp, most oils aren't properly protecting your engine. Ideally, you want temps of around 190 during commuting, and most synthetics these days work best between 220-250*, which is where you want to be during hardcore driving.

I'm one of the owners not jumping on the bandwagon.
I've spent considerable time driving at high RPMs in 90°+ temps in traffic, on the highway and driving in the mountains. I might even be one of those obnoxious drivers that downshifts for no reason... although I think that the noise produced by SRM and a FI TDX CBE is a pretty good reason.
In all of these situations, I've only once witnessed my oil temperature get up to 230°. Most of the time it's right at 220°.

I don't think an oil cooler is necessary for a street driven car that doesn't go to the track.
I also think we wouldn't be having these discussions if we didn't have oil temperature gauge. Given the varying testimonials on what oil temperatures people are experiencing, I question the gauge's accuracy to begin with.
