Oil temp questions
 

I went out today for a bit to run some errands, the temp today is 90 degrees and sunny. I know that people with the 370 have oil temp issues, but I thought I would ask after doing a search for what "normal" oil temps are, I found a bunch of different answers.

I will put it this way... most of the driving was on back roads at 50 mph, and some town driving... even on the 50 mph roads with the cruise on the car was running about 210 degrees.

When I got back I called my local dealer and I told them about the airbag light not going off when my Fiancee gets in the car, and that the oil temps seemed very high for the kind of driving I was doing. I mean I didn't even go over 3k rpms... it's a little ridiculous. I said " I guess you all will have to put another oil cooler in the car or something because i'm not paying for an aftermarket one.

I am almost willing to bet they blame it on the car not being broken in... either way though, what is "normal" for our cars?

I have an appointment on Tuesday to have it looked at.

210 is totally normal for average operating conditions given current MD weather.

:iagree:

210. Just be glad it's not 215. Kidding. Your more than fine. I run 215 around town with an oil cooler at those temps.

oh ok cool... I just figured without getting on the car or anything 210 seemed a bit high.

After my morning commute (~80 degrees out) oil temp is ~225. You really have nothing to worry about there. :tup:

The airbag thing is pretty weird though...

yeah, lots of people are having that issue it seems.

Ok all, went out to run some errands again today. 90-95 degrees (car said 95, phone said 90) and NORMAL driving... no getting on it at all... driving the speed limit everywhere 30-55 a lot of backroad driving. Oil temp 220 degrees. That seems quite excessive for this kind of driving IMO.

Going to email Nissan right now.

Again, totally normal. Don't waste your time fretting about it. 220 is a temp we've all seen in warm weather.

That is the response you will get.
Honestly, if you start seeing 240-250 under those driving conditions then you might have something to say, but 220 is completely normal.

so do those who run synthetic seem to have lower temperatures?

I see slightly lower temps (~10*) with German castrol vs ester oil.

Just for info sake I was just running oil temps of 200 at 94 degrees in stop and go traffic. That's with a 34 row cooler.

Edit. I forgot to mention I still have my block off plate on. It's covering about 3 inches still. I really could remove it completly with these temps where having. Reason being is in the mornings it's still about 75 degrees and my oil temps only hit about 170

Hmmmm, that just seems really high... is that what your typical car runs? My last 2 Evo's didn't have an oil temp gauge (I don't know why... seems kind of stupid to me for a turbo'd car) so I don't have any old cars to compare it to.

What would you feel to be a 'comfortable' range then?

Oil is "rated" at 212*.

oh I really have no idea to be honest... that's why i'm asking if it's just the car... or are these typical temperatures for most cars these days?

In Texas during last summer I saw 230 during heavy traffic, but the moment I moved it dropped down to 215 fairly quickly.

I am about the change the oil in my car soon and then ... once I decide what to get.. will go the intake route as my first mod, which will likely be the drop-ins with the post maf tubes... perhaps that will help bring the temps down a bit more.

Only thing that will bring your oil temps is an oil cooler.

You could always ride around with the hood off.

My oil temp hit 240F driving on the interstate at 70-80mph in 6th gear. Ambient temp was 100-104F. That has been the highest I've seen the oil temp to date. I'm at 2800 miles and have not changed the oil yet but will at 3k.

The area I live in doesn't allow me to drive 70-80 so I can't compare. I wouldn't drive that fast anyway... burns to much gas ... which has gone up this week for some reason after it came down quite a bit for a while.

Driving 70-80 doesn't really burn much gas IMO. I usaually get 21-24 miles on avg. at those speeds. As long as the road is flat.

It doesn't burn less lol. My last tank was 25.6 average with only 1500 miles on the car. I do realize that some places you pretty much have to drive 70-80 mph or you'll get run over.

^ great point. Lol. But you knew what I trying to say. I don't drive many highway miles. Can't wait to see what a tank can do.

Austin hit 104 today. On the drive home from work, I noticed a peak oil temp at 240. 1800 miles to date, no oil change yet. How much does an oil cooler reduce the temp?

When you add this, your good to go. Your basically addding a radiator for your oil along with the extra oil capacity.

Do you have a thermostatic plate installed? I got the GTM 34 row installed with one a few days ago and now I'm having a hard time getting to 180 with normal driving even when it's fairly hot outside. I remember reading that some of the oil still has to run through the cooler with the plate installed but I'm just wondering if it's time I build a block off plate?

Yes I have it installed. It can be hard to hit 180. Even mine was 175 today at 89 degrees with my block off plate covering about 4 inches. But that's the beauty of it. That was not in traffic. That's a different story. Check out my block plate design in my sig below. Rep if you like.:tup:

Adding an Oil Cooler was one of the best mods I've done. I should of done this when I first bought the car.

Here in Socal it's been hot lately driving on the freeway with no traffic cruising about 75 my oil temps go no higher then 95 -100.

That's actually really bad...way too cold. Operating temps should be 180-200.

not to mention the stock oil temp gauge starts at 140...

i was out by palm springs last weekend, 106 degrees outside temp and i was pushing 230 - 240 on oil temp and i kept it below 3000 rpm for a good stretch. i plan on getting a oil cooler

:rofl2: yeah...maybe he's talking about Celsius?

Oh guys my bad, I meant 180-195 sorry heh...

Oil Temp
 

I agree, 220 is perfectly normal. But I want to add that my dealer used a dufferent synthetic my last oil change, was cheaper too , than ester oil, and my temp seems lower by 5-10 degrees. Also, highway driving has a lower temperature than under normal street conditions. Its all normal if you read the manual.:iagree:

I was curious so I looked at the manual:

After I installed my oil cooler my temperatures never go above 210

good, but 210-220 is normal and a bit above
:driving:
