oil cooler

ImportConvert

Ok, let me put this more on your level.

Plate cooler gets oil too cold.
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?

Ok, once again, youre trying to relate GM to the Z. GM had problems with oil coolers and redesigned their crap, [sarcasm] SOOOOOO every oil cooler must be crap and therefore not used until it matches GMs far superior engineering. [/sarcasm]

220+ degree oil temps in a Z is not healthy for an engine, IMO. From an engineering standpoint it might be fine. Either way, I DONT GIVE A F*** about GMs experiences with oil coolers on Vettes.

-220* oil temps are just fine.

-This is a discussion about engines and oil and manufacturer names are just incidental.

-Plate style coolers tend to over-cool the oil. Further, unless you install a bypass for them, they aren't the safest setup. 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.

Dark Sarcasm

maybe, but installing an oil cooler to keep temps at 200 is fine also

no, its not incedental, you placed GM into this thread as if no one should use oil coolers b/c of GMs crap.

^ NOW THAT ^ would be a great post that brings a good technical point to the thread. And yet it had nothing to do with Corvette ********.

ok

Well noone gives a damn that Nissan refuses to put a cooler in the car. I figured if I introduced the fact that another company actually spent R&D money to REMOVE one half a decade into the production cycle, maybe people would take note. Nah. People still want to buy a damn oil-cooler when the needle crests 220*.

You can turn this into a brand-war all you want. I really don't care. I provided you with a real-world example of a manufacturer changing production 5-years in, and spending money to do it. You want to make it a pissing contest? Have at it. Everyone else can take the point as it was meant.

THAT is who my post was aimed at. The OP.

If you track your Z, by all means, I think it should have an oil-cooler. One with a bypass and thermostat.

If you don't track it, and aren't hitting limp mode, don't get one.

My posts in this thread have been about people who want an oil-cooler "just because they think...". Not people who actually tap the limp-mode.

As to GM and their engineers, there is a reason Ferrari and a lot of others pay GM royalties for the technologies they have developed. Say whatever you want, but Nissan had to rent their engine technology from Ford. Ferrari gets their active suspension from GM, and lots of others barrow from elsewhere.

oh thank you oh great Vette prophet for bestowing upon us great Chevy facts.

yes in a world like we have today, companies always borrow things from others because its cheaper, not because its the best solution.

actually im sure what he is referring to is the GTR cylinder wall tech that someone developed at Ford, which is really bad ***

Do you know how we can modify our engine blocks coolant/oil channels to achieve the same affect that GM is doing? Your "contributions" on these forums is seen as little more than trolling.

You missed the boat. I did not intend for you to undertake any such engineering. I simply posted that little-known information as a way of showing you how much issue a plate-style cooler can cause that a corporation as large as GM, after implementing it on a car for half a decade, would spend the time and money to get rid of it. That's all. Now if you want to go and add it to your Nissan because its not a GM and so no information pertaining to oil and engines that GM has is pertinent to you, go for it, man, I really don't give a damn, just trying to throw some info out there for people to ponder before they do something that they THINK is a good idea because IN THEIR OPINION 220* is TOO HOT for an engine.

Nissan put the limp-mode at 260. Probably put it at a safe point.

If you want to talk about trolling, lets talk about people encouraging others to spend money on **** they don't need because of their opinions.

Right, you didnt exactly say "design a better system" you just said "dont run a system that has some drawbracks, even though there is no alternative."

220 oil temp is safe yes, but i easily saw 240+ on the street here in NY. While the temperatures wont damage the engine, they certainly resulted in noticeable performance loss, not to mention the fact that the oil itself will thin out and wear down faster at those temperatures.

Oil gets well over 300* in the engine at certain points in its cycle. 240* in the pan isn't going to kill it. Yes, it will break down a touch faster, but with a good oil that shouldn't be an issue. It's well within the oil's designed operating parameters.

On the flip side, if you put a cooler in there, during the rest of your normal driving the oil might well be 150-170* and not protect nearly as well as it is thicker, has more resistance to flow, hurts fuel economy, and is not up to it's designed operating point.

There is a reason GM went to the trouble of preventing their cars from running around with mid 100* oil-temps.

Your "follow GM" solution holds no value here, GM did not just remove the cooler, they designed the engine in a way to keep oil temps inline. For those of us that dont want our oil temperatures in a range where it affects performance and breaks down oil faster, all we can do is run oil coolers with a thermostatic plate.

Regular 'vette has no cooler. Does just fine with oil temps 220-240 all day long, but hey, you guys blow your $$ however you want. If you feel better getting groceries with an oil-cooler, knock yourselves out.
