Here are some data of the pulls showing the higher boost figures.
Why the seasonal switch?I got both. Plan on using the 40w in Summer.
Why the seasonal switch?
Because Phoenix. I use 10w30 in the winter and 10w40 in the summer. Of course winter in Phoenix is a bit of an oxymoron.Why the seasonal switch?
There really is no a reason to switch oils with a 5W40 - the hot temp viscosity of a 30 vs. 40 weight is irrrelevent to the temp changes in most parts of the U.S. as ambient will have a nearly zero impact on the viscosity of oil at operating temps. Now a 0 vs. a 5 winter rating could have some merit if you live where its routinely below 0 for cold starts.
Can you get a higher temperature thermostat for the oil cooler?Ambients have dropped in Charlotte. Temps on the highway are only getting to 160F. I’m going to have to block off my oil cooler in the Winter for street driving.
Holy crap....160 after sustained driving? So that oil cooler does work...ahahahahaha. I have a neat plot of some data I have been collecting w/r to oil temps in my wagon...this is a IS38/Uni tune, 3 different oils I have been collecting data on. I have collected these data over a period of time on the same commute (all highway) at the same speed (70mph), at the same time (driving time since start to collect reading), and going the same direction (to handle the slope as it’s downhill to work and uphill home…a 150’ elevation difference and I do note higher temps on my return trip at the same ambient). Elevations are in the 100-250’ msl range. I’ve controlled the variables to the extent that I can. Slope is basically the same for all 3; if you went to a 30W you'd expect the lines to shift down a bit.Ambients have dropped in Charlotte. Temps on the highway are only getting to 160F.

I did not - I looked at my oil temps a few times and recall 250 or so? Maybe higher? My max speed on the back straight before my brakes died was 130mph. I think this year I'll just put on my offroad screen on the infotainment that shows oil temp so it's easy to see.Did you run data at VIR? What was your Vmax on the back and front straight?
I have a 215F thermostat internals kit that I can swap into my thermostat. Got it it for this possibility. It will help for the street. Not sure how it would impact track temps. Hopefully I have sufficient headroom built into my cooling system that it doesn’t impact track temps negatively.Can you get a higher temperature thermostat for the oil cooler?
