For those of you with an OBD-II reader or other aftermarket gauge, what oil temps do you usually see?

I just got the Torque app and a good OBD-II reader a few weeks ago and was watching the trends. I have seen generally around 190F around town but on an extended highway trip on a 90 degree F day it settles around 220F.

I'll have to check mine out next time I'm in the car. Been spending a lot of time driving my wifes new QX60 lol.

AA...how did you get the oil temp to read? I don't see it in the list of Torque as a possible display...just IAT, coolant, etc.

It is an option with the Infiniti add-on in the Play Store. It is labeled something like VVEL Oil Temp.

Ahh, gotcha. I'll have to add that.

EDIT: Can you confirm the name for sure? I downloaded something called "Advanced EX for Infiniti" for $5 and it didn't have the M56 listed. Is that what you downloaded?

Here is the page: https://play.google.com/store/apps/deta ... d&hl=en_US

Yes that's it. Select the G37 VQ37HR (V on engine model is missing on app) engine series. It should still work with the 5.6 since it's likely the same PIDs.

After this step, you have to go to Settings, Mansge extra PIDs/sensors, and choose to Add Predefined Set where tou will select the Infiniti G37 option. Once added, then you can log and watch in real-time these values.

Note: does anyone have a good way to display what is logged graphically?

220 is just fine, 270+ is when you need to worry and you wont see that unless you're on a track. Even then a quality synthetic can handle it, I just wouldn't keep pushing without a cooler.

220 is not fine! you need to be around 180.

Go read the 370z forums. Hitting 220 on daily driving is too hot and one of the reasons why Nissan added a stock oil cooler. High oil temps is a con for the 3.7L. Maybe you should go read the negative car reviews online for your engine.

Read car reviews for technical info is a joke right? I know what temps matter to oil, the engine is irrelevant assuming it is a modern engine that is generally in good shape. Also, adding an oil cooler doesn't mean it was a problem, OEM's often make changes to cut down on service calls. I imagine it is partially that, as well as to satisfy owners that actually take their vehicles to the track. Just because people talk about stuff on a forum also doesn't make it a problem. Do some real research and you will see that oil should stay below 270-275 and if you hit 300 you could be in trouble. At what temp does the engine go to limp mode? that is the indication of when you should worry about the temps.

For most M owners, this is also moot because oil temps get higher based on sustained high RPM's. I would be surprised to see one on track turning hot laps. I know a couple people autocross but those quick runs aren't anything to worry about. And if you're driving hard enough on the street to get the oil temp into limp mode, well that's just unnecessary.

Just for reference, here's a video of a guy from Improved Racing that talks about oil temps and cooling. There is also a ton of info on www.bobistheoilguy.com

IIRC, the second number in the multi-viscosity oil is what the viscosity of that particular weight of oil at 100 degrees C (212F). This is probably an important number. I suspect it is a reasonable target for most auto makers to shoot for so they knew what oil weight to recommend. The difference between 5W-30 and 10W-30, for example, make no difference at operating temp if it were at 212F. The difference is the viscosity of the oil as it warms up from cold - and depending how cold it gets (are you operating from a cold start in the arctic, vs cold start in the Middle East).

Amsoil has a good tech article discussing this without going too in-depth here.

Upon my reading some other forums, BITOG, and other technical publications, I believe 220F is not bad for a daily driver. It probably is actually ideal to ensure any gasoline that entered the crankcase from blow-by and a rich-mixture start gets evaporated quickly preventing it from ruining the properties of the oil. In my totally unprofessional, loosely self-educated opinion, I believe oil temps in the ranges I asked about are perfectly fine for long intervals (I've been running 7.5k mile OCIs with Pennzoil Ultra Platinum and a Fram Synthetic filter [both are top tier products on BITOG and other reviews]). If I was racing this car on a track and keeping the oil temps up in the 250+, I would do one of two things - run a heavier weight oil (10W-40 or 20W-50) since at those temperatures it will be too thin otherwise -OR- run an oil cooler (and still probably go 0W-40 or 5W-40 oil).

212 is the target temp for the reasons listed above. The first number of the oil weight can make a difference for the operating temp since multi weight oils are basically blended to get the dual purpose, but it is tiny and nothing to worry about your super OCD or have specific engine needs.

Even at 250+ a quality synthetic 5w-30 is fine, a heavier weight will actually increase temps slightly. I run 5w-30 Redline in my track car and it was steady 300 before I put an oil cooler on, now 250. Used oil analysis didn't show any excessive breakdown in either case.

So I finally got around to using Torque to see what my car said.

It seems that at idle my car is at 199*. After some spirited driving with many high RPM down shifts and powering out of corners, I saw it reach 214* (mind you, this was not balls to the wall driving as I had my wife with me, but it was definitely a bit more aggressive than your average drive). After I got back on the highway (albeit with some Friday end of day traffic), it seemed to level off at around 203/204*. Today's temp was in the low 80's.

This is a 2011 M56x with 123kmi and has been running 0W-40 Mobil 1 every 5kmi for the last 80kmi or so.

Ilya , that's perfect -textbook temperature behaviour. And all cars can be varied in minor ways - you got a "good"one , I'm sure you know it too. If that's now, summer too ,upstate NY , got a good motor getting it's
"cool" correctly.
