The one on my 80s toyota is like this
My 2005 Tacoma has one very similar to that, so apparently Toyota hasn't really changed it for a long time.The one on my 80s toyota is like this

My comment is - unless you are monitoring it and control the variables, monitor outside air temps etc. - you don't really know that.I don't have a fancy graph, but I am averaging about 5 degrees cooler overall with VW 504 0w30 over VW 502 5w40s. FWIW?

I've never thought about elevation at all b/c I'm near sea level and at most, when I go to the mountains here on the east coast, it's ~2K feet tops.VW is really good in keeping temperatures under control. Their EA888 engines warm up fairly fast (also depending on transmission. My Tiguan has coolant at operating temperature within 3 miles). But ambient temperature is not really a problem, an altitude is.
Their oil/coolant exchanger is fairly small and it shows at altitude. Aggressive driving to top of the Pikes Peak will send coolant gauge in my Tiguan to 3/4 mark in no time once I pass 10,000ft regardless of ambient temperature. It happened when ambient temperature was in 40's.
In EA888 Gen3 I think oil sump is larger so that helps for sure, but you ain't gonna see those temperatures being so consistent here.
Yep. You are fine. That is why you don’t have issues on the track. Here, no VW can do track day without CEL if ambient temperatures are above 80 degrees and no upgrades in cooling system.I've never thought about elevation at all b/c I'm near sea level and at most, when I go to the mountains here on the east coast, it's ~2K feet tops.
Anytime you have more air flow through a cooler, it's going to decrease the outlet temperature of the fluid being cooled. This is also true with coolant radiators that feed coolant-to-oil coolers since those coolers feed off the cold side of the radiator. At highway speeds vs city speeds, the engine's coolant temperature coming out the cold side of the radiator will be cooler too.Winter and summer here in mid-Florida my oil temp is around 175F around town. Interesting that on the highway at 75-80 MPH the temp drops to 165F. The water temperature is always around 185F regardless.
It won't be low enough to make much difference ... I'd like to see formal data of how much cooler, especially on a vehicle with an oil cooler. A thicker oil if a few degrees hotter will still provide better viscosity/MOFT protection between moving parts.PS: "It would be interesting to see the same data plotted for a xW-20 and xW-30 oil to see how the viscosity changes the trends when used in the same engine."
In my experience the oil temperature is always lower with thinner oils, and therefor it does not thin as much for the same load.
