Everyone with oil temp issues

theDreamer

No offense, but I would say probably most people will never have an issue with the oil heating problem. This is a bit more of an enthusiast forum so we have a lot more people taking their car to a track and having this issue. By the claims of Nissan, this is a non-issue though since the car is not sold as a track car.

Yep

And by installing an oil cooler, they see that as a competition part, and may deny warranty coverage.

That said, I managed to get my oil temp to 250 yesterday, with some pretty hard accell/decell/accell - it was around 100F yesterday too...

I really had to get into it to get it that high, and it'd cool off pretty easily with some regular driving - in fact, I'd wager that the only time it'd get like that is if someone is REALLY pushing it on the street (much more so than what is legal), or is on a track.

Now that mine is past break-in (about 2500 miles on the car now), and I changed the oil to the Nissan esther, I seem to average between 220 and 230 with normal driving. It's in the 90's here now, and I hit 250 today with a little spirited driving, never exceeding about 5500 to 6000 RPM. I would venture to say had I pushed it a little longer time wise, and/or approached redline, I would have hit or slightly exceeded 260. I guess the 64 thousand dollar question for me is "are the internals used in the engine up to these temps for prolonged amounts of time, and what would constitute prolonged time"? I remember reading in another thread about the bearings not being as hard nor resilliant as they used to be, as a result on changes in the metalurgy brought about by environmental standards. I would love an engine expert to chime in or be consulted as to just how high of temps this engine will tolerate and for what length of time. That would answer alot of questions for those of us that don't track the car, but still enjoy driving it the way it was meant to be driven, and live in hot climates.

If you are very concern, change to Amsoil synthetic, you should see a slightly lower temp. They also tolerate heat much better than dino oil and are capable of 250-280F easily

Thanks. I was actually much more concerned with the engines internals at higher temps than the ability of the oil to hold up to those temps. I'm going to stick with the Nissan Esther for the time being. Changing at 3750, I doubt it will be experiencing serious breakdown at that mileage.

I'm definitely not an expert, but the threads that claim 'soft metals' often list those to be 1) aluminum, 2) zinc and 3) tin. I looked up the melting point of these metals and aluminum was >600C, zinc >400C and tin just over 200C. I'd be amazed to hear any internal engine components are made nearly entirely of tin. Thus, any component deemed 'soft' by these threads is really not at any risk of melting at engine temps under 300C. I doubt they'd be very deformable so far from their melting points as well.

Some people have a maturity level that exceeds a 5yr old, and don't take comments on the internet seriously...

This isn't my350Z.com dude, takes a lot to incite a riot over here
