Your idea of getting on it shouldnt bake the oil to 280 and pretty much everyone has accepted that. but if your cruising down the highway at 80mph and your oil hits 230-240 then theres a problem. And again, as many people have said in many many many many many many threads, that some poeple have it worse than others.

just with me in traffic when i first got it it would hover at 240. it was 105 at the base of a mountain i do some carving on. started at 235 and within a minute i was at 250. well put man well put! I wonder what nissan's explanation is on the varying problems if there is any.

Also was forewarned by other 350 enthusiasts that if I was going to purchase and modify it the first thing would be to get a oil cooler. Wasn't a mystery in the 350 and is more obivious in the 370. If you think 220-240 is ok for normal oil temp then more power to ya.

You know most oils are designed to be run in the 220-250 range, right?

^ What he said. If you're getting up around 230-250 in the hardest settings (type of driving, weather) you plan to drive your car in, it's really ok. You might eek out a few extra horsepower by keeping everything slightly cooler, but meh. For me the breaking point is 260 on the oil temp dial in track conditions. If I can't stay stably under 260, I'd upgrade my cooler. I expect this will be the case early next summer, so I have all winter to think about my options for upgrading from the 19 row Setrab

I talked to a speed shop in torrance and the guy said it only takes off about 10 degrees of heat. My 34 takes off about 40-50 with it being over 100 outside and thats with no mocal thermo plate, just the kit from nissan. I definitely recommend the kit from Z1. If you plan on hopping your car up, the 34 is worth its money in gold. Or you can just buy the smaller cooler and ad a second one from the kit at gtm.

So answer me this then. Why is it, that when i ran my car with my oil cooler and it was 95 outside and i did a total of 30 mins hard drving that when i got home and pulled the stick, my oil smelt burnt. AND IT WAS NISSANS ESTER BASED OIL. Fresh testing from the dealership, not even 100 miles on the oil before the mountain driving. Oil temps never exceeded 225. So I honestly think, and this is my opinion that your idea of 220-250 normal range is false information.

im just saying

wstar · 08-29-2011, 04:04 PM

And this is based on hard oil science, or you deciding it "smelled burnt?"

225 isn't going to hurt any reasonable motor oil.

roy'sz · 08-29-2011, 04:06 PM

slight color change and the smell sold me. Just because the oil isn't black doesn't mean it isn't burnt.

Cool,thanks.

What exactly do you mean by burnt (other than a smell)? Typically, burnt oil means it has hardened/glazed to a varnish. All oil changes color and smell as it gets used, that's completely normal. I guess I'm struggling with the subjectivity. In any case, the real issue with oil temps in the Z isn't the breakdown of the oil itself (many synthetics will remain stable up to 400 F); the issue is the bearings that are internal to the engine. Years ago, Nissan switched to a softer metal that is more susceptible to warping under high temps. That's why high oil temps -- even if the oil itself is okay -- are bad for this engine. Indeed, it's probably why these cars have a limp mode.
Do a Google search on "370z oil temps bearings" and the very first hit will take you to an article that explains all this in detail. The second link explains it as well.

i have one of these. unless its 80 degrees outside it actually works TOO well while driving normaly. if its kinda chilly outside, and im driving on the highway at 80mph it wont even get above the lowest reading on the guage "140" i think.

but at the track, ive never seen it above 210 with the kit, using royal purple. and thats going balls to the wall for multi lap.

downside imo is that it cost me 1100 with installation........

You should really put a blockoff plate on your cooler in those conditions. Driving around on too-cold oil is bad for the engine, too, especially if you push it hard at those temps. I usually shoot for a 180 minimum before I ask the car to work very hard, and I don't think I'd be comfortable even on a low RPM highway cruise if I couldn't sustain at least 160. If you're off the bottom of the gauge who knows how cold it is really.

Hi all..New to the forum. I understand that the 2012 370's have a "small" oil cooler adjoining the oil filter. this arrangement is found on other Nissan models. Any one know of this & could it be "retro'd" to my 2011? Thanks roddyracer
