Everyone with oil temp issues

lww

I thought the same thing until I went to the blog site and saw that the other cars were running R compound tires and many were heavily modified. A modified MiniCooper S with R compound tires is nearly a jet powered go kart!

There's no way a stock 370Z on OEM tires could keep up with those things in the corners and depending on how much the Mini owner has done to his turbo/SC power plant, even in the straights...

Here's the actual blog post: http://www.zcarblog.com/2009/04/15/3...l-raceway.html

I used to have a turbo'd Miata - those things are NOT slow once you put a turbo on them. They're tiny, light, and rev like crazy too. 240-ish RWHP may not sound like much, but in a car that weighs 2100lbs..

You really need to be on a track with a Miata which has had a V8 transplant. I was at VIR a few years ago with one. It was amazing!

yup ppl who talk s#!t about miatas don't really have any say in the enthusiast world. Miatas are probably one of the most potent lil boogers once it's been tuned correctly. 2100 lbs, rwd, very tossable, etc. Miatas with f20c swap = gg.

Here in Tucson, AZ. it was 97 degrees. Just cruising at 3K rpm through town my oil temp reached 240 degrees. I remember seeing some people wondering what would happen when summer heat hit, so I figured I would post up what I saw.

FYI, before today cruising oil temp was usually around 220.

thanks for checking in... manual or auto ?... pushing it towards redline or just bumping around 5-6K ?

import111

Manual. Shifting before 5K rpm. Mostly cruising with no stop lights.

Good fawkinnng game nissan. That is absolutely ridiculous....i cant wait til us socal people are sitting in traffic with hot oil on a 100+ degree weather. This should be VERY interesting. The sad reality is that 95% of the people won't even know that the engine's gone into limp mode since they won't be pushing the car enough to hit lowered rev limiter.....and they'll drive the car in 300 degree oil temp a big chunk of the car's life, essentially reducing engine life without even knowing it at all.

travisjb

there is a second limp mode... if you continue long enough at that temp it drops again - I recall 2,500 (First track experience today ! Some good, some really bad)... that'll get their attention !

Just though I would share...

I’ve had my 370Z since early January 2009 and have about 4,200 miles on it. During that time I’ve taken a couple of long trips where I’ve generally traveled about 10 miles over the posted speed limit (at least when traffic permits) which for most of the states I travel that's in the 80ish MPH range and I’ve autocrossed my car twice so far. I’ve also, as you know if your read my earlier post, taken my car to the Dragon and the Skyway recently.

<o></o>As hard as I’ve pushed my vehicle, the oil temp, according to the onboard gauge, has only reached the range of 240 up to near 250 degrees. A few days ago, I discussed this issue with the owner of Crawford Z Car in Nashville – he’s been repairing, and modifying and racing Zs in particular and Nissan’s in general for over 35 years…there are few people in the country that know more about the Z car than he and per him, if I understood him corectly, we shouldn't have to worry about oil temps until they hit the 260-280 degree range and that 220-240 is just about the range you want your oil to operate in.

<o></o>One thing that neither he nor I know is exactly “where” the onboard oil temp sensor is in the 370’s engine…if it’s in the pan, it’s going to be hotter than at other places (which is pretty normal) per him.

This pretty much puts the issue to rest for me...my feeling now is that if you are going to track your car or routinely thrash it and run it to the edge every time you are behind the wheel then get an aftermarket oil cooler installed…other than that, the oil temp should not be anything to be overly concerned about…just keep you oil changed regularly.

That's reassuring.

The Oil Temperature Sender is item number 10 in the diagram below:



It gets its reading right at the oil filter engine housing mount (I suspect at the point of entry oil channel into the oil filter). The picture is rbatton's.:

Thanks for sharing your experience and info. I feel better about the oil issue after reading your post. Change oil and filter at short intervals should provide adequate protection.

travisjb

It is reassuring that the engine temps being picked up are the hottest, I agree...

But Autocross runs are usually 1 min or so... not the best to use for gauging potential to overheat IMO

Also, this one is a 7AT - most of the problems we've seen are with the 6MTs

Robert_Nash

If I understood my racer/friend correctly, temps in the oil pan will be significantly hotter; especially when racing/tracking...if the sensor is there then I don't see this as a big problem.

It would seem to me, in fact, that the EMS is being a little "over protective" if it's kicking in at the 208 range and that temp is coming from near the pan.

I'm no mechanic so I'm certainly no expert...that's why I make friends who are...just doing a little theorizing here!

I also agree, an autocross should not significantly impact oil temps...the runs just aren't long enough even on a very hot day.
