Are you saying you don't think they'd up the thermo temp given what you were told? We've seen pics of the Nismo core, it looks larger than Stillen's. A larger core with only a 180 thermo would easily keep the car at 200-212-ish and below in any reasonable kind of driving, and then when the daily driver does his limited spurts of performance driving, the temps would hardly have the chance to get up to more than say 230 before it was over. Even at the track, you'd have to do some pretty mean warmup to get up to 250+ for the ideal temps your Nissan guy was talking about.

To me this doesn't seem to add up with his statements about how banging on the engine with colder oil (what we consider normal, 180-220-ish, with spurts to 240 perhaps under hard conditions) is more detrimental than letting it run hot (250-280-ish).

So all I'm saying is, I expect the Nismo cooler option to have a thermo, and for that thermo to be set significantly higher than 180, for any of this to make sense. 220 would be reasonable, maybe 230-240 though given what he's saying.

My gut feeling is that their thermo, if any, will be at 180 and invalidate the guy, but I could be wrong.

Just read SoCal's GTR link too. They're stating an extended oil drain interval if you keep the oil under 230, a shorter (but reasonable) one if your oil is running in the 230-266 range, and 'change as soon as possible' if you break 266. Different engine (and different recommended oil), but it's still Nissan, it's still based on the same platform, and those numbers look a lot more reasonable and normal to me than the idea that 250-280 is 'ideal' for our engines when running hard.

Would the GT-R's Turbos have anything to do with that? I know they are lubed by the oil. Too hot= coking? Just a guess. I'm just giving you the info I heard. I don't want to get flamed. I just never get why a business would want to lie to get ahead. We'll see. I'm glad you are all feeding back.

I'm with Spearfish. We're getting a warranted oil cooler. That's cool! Literally! (Oh, Spearfish, it's a Nissan Motorsports one. Is that Nismo? I'm a rookie with that brand. I'm usually Mr. Stock.)

I'm not trying to flame you, but I am saying I have reservations about the veracity of what you've heard from the guy you talked to.

Well, a bit more time and we'll have many of these answers. Don't overlook one very important piece of information TheWeatherman got for us. They are saying the Nismo Oil Cooler will be dealer installed and fully warranteed. Even if I have to pay for it out of pocket, that's a victory in itself.

Interesting that Mocal, one of the larger suppliers of Oil Contol systems makes the 180 degree thermo standard on all their thermostatic sandwich plates (what I just put on my car) Info: http://64.202.180.37/files/sp1t.pdf

Another interesting factoid: The High heat temperature that is used to calculate Viscosity in standardized oil testing is 212 degrees..
