Oil temp question

vtec to vvel

sidebar question:

the highest temp. my 09 Z has seen is right under 220. what is the safest temperature before the "danger" zone?

Most oils are good to 300 F or more. Limp mode (280 F, IIRC) will protect the engine. Keep oil temp between 210 and 260 F and you should be OK.

gotcha, I wasn't sure, as I have been hearing mixed things. I have an 09 (no stock oil cooler), and every time I see the temps near 220, i usually panic.

I've noticed, though, that if i turn on the AC, it somewhat cools the temps down?

When you turn on the A/C, the car kicks on both radiator fans.

Curious what is the upper limits for the dyno and full synthetic oil in general?

My 2010 is at around 200 - 210 during normal driving with outside temp around 80's.

My attention to detail is off... The oil cooler is there.

Texas chuck, the oil i used/use is amsoil signature series 5w30... Let me dig up that report for you

Ok so we established the 13 MY 370z came with a useless factory oil cooler. I am yet to see any major posts showing evidence that this "update/revision" reduces oil temp compared to prior Model Years.

It's really not useless, if anything it helps bring the car up to operating temperature quicker. Really it just helps keep the oil from getting too hot better than the 09-11 (though this is definitely a track band-aid). It won't really do much when your temps are between 190-220.

Ill find that damn Oil report, having to look through several usb's of mine smh

On another note, I ve decided to bypass amsoil and test redline because its more ester based oil

Looks like you may have already gotten things figured out, but FWIW, I have a 13 with the factory oil cooler. I recently added a 25 row Stillen oil cooler and am using Mobil 1 5w-30. Prior to the oil cooler, I would hit 210-230 with spirited driving in town depending on ambient temp. Now, it will stay right at 180 on the highway, 190-200 with spirited driving regardless of outside temp.

On the track, I was out for sessions of 15 minutes each. I was flooring it through all but braking/corner entrances and temps never broke 255. I actually like keeping the factory oil cooler because it helps keep coolant/oil temps consistent and actually heats the oil up to operating temp much quicker. The factory oil cooler does have one drawback, which is that it makes it very difficult to route cooler lines and the oil filter is very difficult to access compared to normal. That said, it takes maybe 1 minute to remove the oil filter whereas before it was 15 seconds. Happy with everything thus far.

4 sessions at 15 minutes each and never breaking 260 is pretty amazing. Im excited to run redline after all the good press the corvette guys give it. Im hoping it will bring temps down a bit, but an oil cooler is in my future shortly

redline is the car. Everything feels smoother and the car revs easier. Temps seem to be cooler by about 10dg more than pennzoil ultra platinum. Tonight Im going to go drive it pretty hard and see where my temp end up

slightly off topic.

All of you that added the oil cooler did you add a oil pressure gauge to monitor for leaks? I was thinking of adding one, but am I just over paranoid?

GZ3

I may have spoken too soon. Temps are significantly higher with redline oil even though redline is smoother. Pennzoil Ultra plantinum seems to keep the car 10-12 degrees cooler. I did my usual "abuse run" and the temps were 225 after it all...I would really have to punish the car to get 220ish before.
