So then I guess I would need to find out at what temp the type of oil I use starts to break down and lubricate as well.

While each brand of oil should show some differences in exact temps, but from a couple quick searches, most conventional oils (which I assume includes Nissan Ester) starts to break down around 250°F and most synthetics appear to be rated up to around 290-300°F.

But what complicates things is that article explaining that the problem for this car isn't that the oil gets so hot that it starts to break down; the problem (according to the author) is that in an effort to be more 'green', Nissan changed the type of metal they use in their bearings, and the new metal is less durable under high heat. The claim is that even if your oil is okay at, say, 280 degrees, the bearings aren't -- they'll start to degrade. You guys know which article I'm referring to? The one by Mike Kojima?

I hope they are not using those clay bearings from the clay model they have sitting around.

It's why I installed an oil cooler. I'll tell you guys right now that I never saw temps above 250 prior to installing the cooler. But the claim made in that article had me paranoid enough that I figured better safe than sorry. And on the cooler went.

I won't link to the article itself because it's on a competing blog and it's against the rules, but I did just go find it and I'll quote the relevant passages here for you guys to read.

Oops. I missed a couple of additional paragraphs.

I agree with Semtex. I read that article awhile back and it really got me thinking about the oil temperatures in my car. To be honest I never see my oil temperature go above 220-230(but I haven't driven it hard in hotter weather yet). But, if I see temperatures substantially higher, but still not in limp mode. I may consider an oil cooler without being on the track just for the sake of ease of mind.
The biggest thing that makes no sense to me is. I'd say a VAST majority of members on this forum mod their cars. So why complain about an oil temperature problem with this car if an oil cooler is one of the cheapest mods that can be done to the car? Stop complaining and fix the problem. I'm sure the 350z had this same problem. But without an oil temperature gauge or limp mode ignorance is bliss. |

I don't know about you, but after spending $30K on a car spending >500 on an oil cooler seems like a pretty cheap mod. I plan on my car keeping value rather then imploding over that fraction of money. Especially when Exhaust systems are 3-5 times the price(some a lot more)

I think one of the issues with an oil cooler is that Nissan doesn't like us installing them. While I mod my exhaust and cats, Nissan shouldn't have any issues with something happening to my engine. If I install an oil cooler, I'm not sure of the results.

Right, but that brings you back to square one. If you're afraid to put the oil cooler in your car then don't drive it until it overheats. More or less what Nissan has said to its drivers, on the street no cooler, on the track cooler.
