oil cooler

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.

That would be great if our cars stayed in the 220-240 range, I could only do that with the AC on. Oil cooler keeps me in the 170-220 range. Are you bored yet? I am.
