oil cooler

OrangeJuice · 04-28-2011, 11:38 PM

To condense all the back and forth down to a simple few words:

Couldn't hurt, but isn't necessary.

There, that's really about it.

Oh...and apparently GM>Nissan

Anyone care to explain?????

As import pointed out, its likely the secondary electric fan that kicks on when the AC comes on. It cools the engine more, which in turn would affect the oil temperatures.

My '95 TA would shed about 20-30* on the coolant temp when those fans came on. Ran with the A/C on in traffic and it was about 190-210* vs. 220-230.

I really don't think it's necessary. If you drive "sanely". I've driven mine pretty hard in 95 degree weather in city traffic with no issues (ever).

But, to each their own.

why couldnt nissan add oil cooler from factory....

because it would have brought the cost of the car over a lot of ppl's price range..

And it just wasnt worth loosing customers over it. 98% of Z owners will never need one anyway

No, you shouldn't.

GM used to put a plate/fin style oil cooler in the Z06. They no-longer do. The ZR1 doesn't have one, either.

Oil coolers cause problems on the street. Now GM has an oil-cooler that uses the coolant to regulate oil temp. It lives by the oil-pan and has no fins, etc. It simply moves the coolant and oil near each other to keep them roughly the same temp.

A lot of Z06 owners from previous years are only hitting 135-155* on the highway oil-temp. My car runs 185-200* on the highway, depending on ambient temp.

So MUCH BETTER for the car.

I would suggest you take a note from GM who REMOVED an oil-cooler like the one you want to install and developed a different one that won't cause as much issue.

your like a baseball fan in the upper deck doing "the wave". No matter how hard you try you will never be a part of the crowd.

WTF do aftermarket 370Z oil coolers have to do with factory GM oil pan fins coolant thing-a-ma-jigs?

MY 370Z runs in the 200+ temps on 90* days. 220* is not uncommon under hard driving conditions. To the OP, a properly installed oil cooler is no more detrimental to your ride than any other aftermarket part. I would rather have it and not need it than need it and not have it.

I agree. How did the convo turn to a Z06 vette? The Z06 is an 75k car.

BLA BLA BLA-highjacker!

It turned to the corvette because the car had the exact mod (plate/fin style oil cooler up front) that people are so keen to get--and GM got rid of it. Spent a lot of money to do it, too. It is the only example I can think of regarding an oil-cooler except Nissan, whereupon Nissan refuses to install it, but that logic wasn't good enough for most people, so I went out of my way to post about a company PURPOSEFULLY getting rid of that type of oil-cooler.

Just thought there might be a reason for it and all that. 150-160* oil is bad. You want it 180-220 for normal driving, and if it spikes up to 260-280 on a track day, no big deal as long as it doesn't sit there all day. Of course, with the Z, it goes into limp mode at 260, so you are protected.

Then some people turned it into a GM vs. Nissan thing because that's what fanboi's do when someone mentions another brand.

If you are tooling around the highway in 6th gear at 65MPH and your oil temps are hitting 230° you may want an oil cooler.

My car unfortunately does this. I can make it hit 260 with a short 2 minute run in the twisties where other Zs don't go over 220.

If your car runs hot buy one. If your car runs cool don't.

My Oil Cooler is coming with my supercharger.

I think there is a very logical explanation for this. Your license plate covers what, 30% of the air intake area for the radiator? Get it off there. (assuming your avatar is a picture of your car)

I thought of that also. Moved it over 4 inches, no change. Then took the plate off, no change...

I have one of the cars that runs hot. Nissan

me, but at least I can put in an oil cooler...

So your suggestion is for us to not use oil coolers because GM doesn't, and come up with a custom system similar to what GM uses. Great, we'll get right on that.

Manufacturer got rid of plate system and spent time/money to develop a cooler that would not make oil cold.
If oil not too hot, don't make oil too cold because of imagined problem.
Learn from big corporation. When big company spend money, usually viewed as a necessity.
Better?

Because the last 5 years have taught us that big companies will definitely spend money where they deem it necessary for the regular ol consumer.... yeah....

You can of course install a thermostat or buy a plate cooler with a thermostat in it, but the point remains that you are doing this because in your mind 220* oil temps are too hot.

-Check your "IMO" at the door IMO is worthless in a technical thread. For once try to support your emotionally charged BS with fact instead of Fanboi nonsense.

before your hashpoint of telling him to keep his IMO out (bolded for you), you simply stated your own opinion as well. Except for you didnt add "IMO". Otherwise as you told him, support your "tend" to statement.

Although I am sure that there are bad oil cooler setups out there. Same way there are situations where an oil cooler is also needed.

Since you seem to be so passionate and informed regarding that style cooler, why not develop it yourself? sell it to everyone and make a killing on it? That is unless, its not gonna be easy to develop, take too much time and money, isnt worth it. And so we are left with the options presented to the OP in the first place.. a 19 or 25 row with a thermostatic plate.

Yah its funny that we should follow in GM's footsteps.. since they obviously employee the best engineers in the world. Definitely better than BMW, who does use a oil cooler on their cars instead of a "lets put coolant near oil!" box.

There's actually a lot about this I agree with.

A lot of Z owners jumped on the bandwagon, feeling the need to install an oil cooler on the car. It's simply not necessary for most users, and many street-driven cars won't get the oil up to proper operating temps with an oil cooler installed.

I've seen plenty of users bragging that their oil temps stay below 170 with their cooler. At that temp, most oils aren't properly protecting your engine. Ideally, you want temps of around 190 during commuting, and most synthetics these days work best between 220-250*, which is where you want to be during hardcore driving.

I'm one of the owners not jumping on the bandwagon.
I've spent considerable time driving at high RPMs in 90°+ temps in traffic, on the highway and driving in the mountains. I might even be one of those obnoxious drivers that downshifts for no reason... although I think that the noise produced by SRM and a FI TDX CBE is a pretty good reason.
In all of these situations, I've only once witnessed my oil temperature get up to 230°. Most of the time it's right at 220°.

I don't think an oil cooler is necessary for a street driven car that doesn't go to the track.
I also think we wouldn't be having these discussions if we didn't have oil temperature gauge. Given the varying testimonials on what oil temperatures people are experiencing, I question the gauge's accuracy to begin with.
