It typically does this when the car is warmed up (oil temp 230-240), but I'm really surprised no one has determined the cause of this yet! I'm taking the Z into Nissan tomorrow to have them investigate this problem so hopefully I can get some sort of answer..

Definitely take it in. They likely wont' do anything (ECU reflash if you're LUCKY, but that probably won't fix it). But they need to know about it. If this ever gets resolved, I'll buy another one =)

I'm gonna do my best to make sure everyone that needs to know at Nissan hears what I have to say. It's unfair that I have to deal with an ECU that puts my car in limp mode purely from daily driving. Hopefully when this is all said and done... OIL COOLERS FOR EVERYONE!

Just picked my car up from the dealership after an oil change and maintenance check up. I drove across the street to Wendy's and my clutch won't come back up after I press it down to put it in gear.... WTF! Dealership is about to come pick my car up and tow it back so they can see what's going on. My car has 10,600 miles on it. Anyone know what this could be? They also said that the delayed throttle response is due to the ECU and that's just how it's programmed. Not much help

Master and/or CSC failure... had mine replaced as well. Master tech also says it has to be ECU programming and mentions emissions compliance. It pretty much kills the fun factor.

Thanks Digi. I'm pretty bummed about this whole situation. I really want to bring this situation up to Nissan, but at this point it seems as though you guys have been at this for a while with no results. Should I just get an oil cooler? This clutch issue caught me way off guard though, just icing on the cake I guess.

Yes... it really stinks. This is your chance to get a better CSC because the new OEM one is no different. Mine was replaced a year ago. It leaked fluid inside the bell housing. I'm currently running the ZSpeed HD CSC. It seems to work well and feels stock. With a new clutch, it does judder every once in awhile. In fact, the car would judder out of the box so it's nothing new. It has been a month and 1700 miles, and my car is a daily driver.

If you plan to track or drive spiritedly and experience over 220F on average, definitely get an oil cooler. You can see if some N/A owners can chime in about their experience. I had mine installed with the turbo kit, so on average I see no more than 210F on a hot day. With temps in the 70s, It is around 190-200. What's really funny is that the fans from running the A/C cools down the oil temps as well.
