How much do you warm up your Z?

No, but the oil temp is up enough to hit the hwy by the time i get to a hwy. other then that i don't drive hard near town anyway.

I used to just wait until the needle started to move, but then I installed my oil pressure gauge. The oil pressures don't start to drop to the lower operating pressures until 180+. Cooler than that, the pressures are in the 100-105 PSI range when you're around 2-3k RPM. That was enough to make me warm her up to 180F before getting sporty with my driving.

yep I think of this when I first start driving it. I think it was your thread

that pointed out how high the oil pressure gets when you push past 2k rpm and temps are <180.

How accurate is the gauge anyways? For example the other day at lunch i went to the local grocery store. It is about 2 miles down the road. By the time i got there, the needle just started to move. Parked, came out 10 mins later and the gauge was then up to 140 or 160.... it jumped a lot while parked which makes me think its slow to move in general...

Car sitting can actually warm the car up, it is just sitting static with all the heat staying around it.
Same thing happens when you drive for awhile and you get to 200 degrees and park for a bit and come out and the temp is 220+.

Gotcha, makes sense I guess...

theDreamer · 03-23-2012, 03:16 PM

Mine is usually a 5-8 minute warm up, which usually the oil temp gauge is just about to start to move. By the time I am out of my neighborhood it is around 160.
Honestly, you really do not need to wait very long, a good 60 second warm up is all you really need just do not go bouncing it off the rev limiter and you are fine.

mantella87 · 03-23-2012, 03:20 PM

180, I stay below 3k until then.

ZMan8 · 03-23-2012, 03:42 PM

Also if you have an oil cooler the gauge is off a little

I dont but im planning on getting one this year. Its been like 75 max outside and my car sits at 220 from normal driving...

This engine oil temp is what you want to see COMING OUT from the motor. In the case of the 370z and any add-on oil cooler, you are actually getting a false reading. Since the factory temp gauge reads engine oil as it exits the Oil Filter, you are actually reading the oil temp coming directly from the oil cooler. The flow pattern for engine oil on a 370z is as follows:

Pick Up Tube --> Oil Pump --> Oil Filter IN --> Oil Filter Out --> Oil Cooler --> Engine Block (Temp and Pressure gauges are located in this galley)

The temp you are reading is actually what is going back INTO the engine (which is perfect). By the time it cycles thru the engine, you can expect to see engine temps in 200 degree range.

As for the thermostatic sandwich plate, it will bypass roughly 80% of the oil back into the engine when too cold. It will still flow ~ 20% thru the oil cooler (preventing air pockets from forming).

To get a TRUE Oil Temp reading, you would need to install an inline oil temp gauge coming out from the Thermostatic Sandwich plate before the oil cooler.

Oil Coolers and Over cooling

Doesnt that contradict itself?

ZMan8 · 03-23-2012, 03:55 PM

I think what it is saying is if you want oil temps of 200, you would want that kind of temp reading on oil coming out of the engine (meaning oil in the engine is at 200). The 370z oil temps are read before going in the engine though. So if the guage shows 180 degrees, then real oil temps are probably 200

EDIT for those new to the discussion this applies to those with an oil cooler only.

haha lovely, so since I dont have a cooler, my temps are actually higher than whats being read... oh boy lol

I hope I am understanding this correctly...

They shouldn't be. Your set up doesn't allow the oil to cool off enough between when it exits the engine block and comes back in
