I have no way of measuring since I do not drive by gauges. I just wait long enough to feel comfortable that everything is up to temperature. This means that in cold weather I don't play on the ramp when I start my commute. Now, since if it is that cold out then even my snow tires are to firm for much fun anyway. I am never sure where all these people that start hooning right out of their driveway live and drive. If I start hitting red line anyplace within about 10 minutes of home or work I am going to either smash into the back of somebody stuck in traffic or have frequent conversations with the nice police officers.

There is no replacement for an oil temp gauge. I’d even forfeit water temp for oil temp if I had to.

Cool. My 860 has both, and I almost never leave that screen.

Well fine then. :P

You know actually if I had to list the improvements on the 2017+ in order I would list them like this:
FD
Oil Temp
Tail Lights
5HP


Hahaha

I wonder if you (or anyone) has graphed oil temperature and water temperature as a function of time, in warming up a FA20 engine?

(yes, I realize that might depend on air temperature and RPMs)

Tons of threads and logs out there. Oil temp always lags by a good margin. I'm familiar enough with my oil pressure-vs-temp profile that I can estimate oil temp within a few degrees.


Without an oil cooler, just give it a few minutes after the water comes up to temp. That's all it really needs.

You'd be surprised at how little ambient air temp comes into play. At least until the thermostat opens that is.

Are you suggesting that I ?

So, are you going to share that profile?

The reason I ask is that what I'm now going by is that I figure the oil temperature is up enough when I can feel the warm air from the heater on my feet -

Yep, If I have to hear the toddler watch the movie "Frozen" one more time - I'm ah gonna completely lose it.

I just went through a few of my logs and found one that starts with the coolant at 114F and oil at 94F. About 6 minutes into the drive the coolant plateaued at 190F. When the coolant first reached 190F the oil was at 158.5F. It took an additional 3 minutes for the oil to stabilize at 185.46F. So in this case it took me 8mins total to reach normal oil temps. But this isn't from a completely cold start. Also IAT was around 78F so this wasn't in cold weather, even for Florida.

Tomorrow morning I will do a log from being completely cold and post the results.

One other thing, I feel like I've read that the water temp gauge on this car climbs up and then stopped just before the middle mark and from there it stops moving even though the temp hasn't reached 190. The gauge only moves above the midpoint if the coolant goes way over 190. When I do my log tomorrow I will take a timestamp when the needle first hits the 1/4 mark and another timestamp right when it hits it's normal resting place and then compare these timestamps to the real data.

That's a little early for the Italian tune-up. Watch the water temp gauge. Give it a few minutes after it stabilizes.


I don't have much choice because I hit I-5 so quickly in my commute. I just short shift and apologize to my engine until I cross the river.

There is a WRX near my office that is always trying to race me on the way home. I run on my lunch break so I know where he works. It takes a lot of self control not to give in and race this guy but you know damn well his oil is cold too because he works just down the road from me. I guess he doesn't care. Hahaha

I haven't logged it, but playing with my P3 gauge in the mornings I see basically what you describe.

Sounds like you need an oil warmer - rather that an oil cooler -
