oil overheating unique to vq37vhr engine?

pauley · 09-04-2010, 10:04 PM

I wish i knew what it was and how to correct it without voiding my warranty. The highest oil temp i've had is 220-224 in 90+ degree heat, so not bad. It's always in the back of my mind that dreaded oil temp. It's a uncomfortable feeling

My oil temp gets to 230 pretty easily here in Texas. (Freeway driving.)

The real question is.... what temperature is "too high" and when should i be worried?

Ill be getting an oil cooler within the next few weeks.

Good idea. I am only at 220*-225* on the freeway, and am often over 250*-260* within a mile or two of spirited driving. I am having mine (oil cooler) put on Sept 20 when they replace the short block.

The Genesis coupe needs an oil cooler if you are going to track it hard. The oil temps easily climb towards 300 degrees, the main difference ... the car has no oil temp programmed limp mode - neither did the 350Z where oil temps could also hit 300 degrees on the HR engines.

If you put a oil temp gauge and a programmed limp mode of 280* then hit the track most to all cars would go into limp mode like the 370.

Not after a couple laps...

A stock s2000 will chill below 240 or so after a day on the track.

HAHA.. nice

so basically all cars overheat the oil, but nissan is the only one that bothered to protect the engine and put the limp mode there? that definitely doesn't reflect too good on the other car companies

Nissan changed the way it made bearings (dropped lead out of the formulation) and as a result saw a rise bearing failures at sustained temps over 300. 280 was the point they decided was a good place to limit to give themselves a bit of a buffer. I have no idea oif other car companies have done the same thing with their bearings.

Many vehicles see bearing failures at sustained 300+ temperatures. The oil thins out so much that it can no longer provide adequate film protection to vulnerable parts like bearings. A few weeks ago I was at a hot track event with a C5 Corvette that was continually pushing 300+, and sure enough a few sessions in he had bottom end engine failure.

Yeah... the Z gets hot really quick. The factory cooling just sucks for high performance applications.

what are your thoughts on how the mustang and 370 compare?
