This was at NCM in late spring. Not even sure I want to be on the track in the next couple months it'll be so hot. This is why they require the 5w50 no doubt. Even some 10w60 would be beneficial at these temps.
Would be interesting to know what temperature the thermostat is fully closed (or open) but I'd bet it's much lower than 250 since oil will not live long at that temperature. There is no operational reason for the oil to be above 200 even. The oil cooler is marginally sized for this application it seems.
I don't think the oil cooler is on a thermostat, because the oil stays quite cool when the ambient temperatures are cold. I've run my car thousands of miles with the oil never reaching 200 degrees.
Huh, it doesn't do much to keep engine oil temperatures constant. If it's cool outside the engine oil stays very cold. If it's warm the oil gets hot quickly.
With an ambient air temp of ~95F I was also hitting 250F on the oil temp gauge. I was trying to vary the speed for break in and do some strong pulls in 2nd, 3rd, 4th, 5th so (going +10 speed limit to -10 speed limit, over and over).
Got an oil cooler. I'd expect the temperature to drop at highway speeds. Are you seeing 220 on the highway?
Good point! I forgot all the GT350s had oil coolers stock. I wonder if the GT350R or TP cars have the same specs for the oil coolers. The range of oil temps seems to be wide and if all the cars have the same oil cooling capability, I don't understand that. You can only drive so hard on the street.
