Oil temps: 335 comparitive observation.

Mitco39

By an engineering standpoint as long as you have a good conductive paste between the oil pan and the fins this would actually work quite well. No different than an electrical heat sink.

I should also point out that before my trip in the mountians I had the plastic undershroud off the car and it would run down in the 180s that way. I might pull it back off to see if there is a correlation between running with it off and cooler temps. I would imagine there would be significantly more airflow around the engine with it removed.

Jordo!

I thought about adding a vent to the undershroud (and I believe there is a modshack DIY for that on here), but I don't remember what the final verdict was on what other effects occur -- poorer MPG by being a bit less slippery to air under the car or changing how air flows over the radiator, for example.

I think it remains an open question without further testing...

The only ill-effect I noticed was that the front bumper wasn't as rigid as it was before. Next time I change my oil ill leave it off again just to observe the oil temps.

It's a shame that our cars cant operate normally at the same oil temps as other modern performance or everyday cars. embarassing even. but there isn't much we can do aside from prolonging our enjoyment by investing in oil to air oil coolers.

I've had my belly shield off for a while before and to be honest, if there was a difference it wasn't noticeable. The front bumper is definitely not as rigidly held in place but i've gone for months with no shield and i spend a fair amount of time on motorways. Ever since i realised i could do any oil change just by popping the rear screws off the shield and folding it back, i havent removed the shield except when it had to come off.

Thanks for the heads up about the stick on heatsinks. You can buy Arctic Silver thermal compound adhesive from computer parts shops. It's an epoxy type glue. You can also buy the adhesive pads from some computer parts suppliers but i haven't seen any that would hold up to the elements. Speaking of which, computer heatsinks are really cheap.

How many Toyota Camrys or Honda Civics come with an oil temp gauge? These cars can and do overheat their oil when driving under severe conditions (city driving, spirited driving, etc). The only difference is they don't know they are doing it, ignorance is bliss.

Please don't start gluing computer heatsinks to the car.

In my opinion, the high oil temps don't bother me, it's the fact the car could go into limp mode due to the inability to control temps while being run hard. While the minority, this is a sports car and there will be people that track it and/or just drive it hard. That's where I feel Nissan missed the ball. I'm sure many cars run high oil temps, and the drivers have no idea, but they aren't going into limp mode otherwise you'd hear about it. They also aren't driven as hard as a 370z.

And as a side note, My 2008 Altima with the VQ35DE had an oil cooler. Same one Nissan probably threw on the 2012+ 370z
