So what is the normal operating oil temperature of the LS1? I have done some searching and haven't really found a good answer. Some say it should be lower than coolant temp, but others say it can reach 280* during agressive driving.

Anyone have a oil temp gauge currently installed?

I am going to order a oil temp gauge and don't know to go for 100-250* or 140-300*. I will be installing it in the oil level switch location in the pan.

Corvettes have Oil temp guages. Normal Oil temp for street driven Corvettes seem to be in the 200 to 210 range. I track the car occasionally and have seen 290 temps. Have an oil cooler ready for install. One of my winter projects.

There is no way the oil temp will be less than engine coolant temp. But to answer your question, oil temps on LT1's are typically around 10-15 deg. hotter than the engine temp.

I have an oil temp autometer gauge installed on my car and it's usually at a little over 180 degrees F. It does get up to about 220 or so after a WOT run, but rarely goes over that. I also have a 160 T-stat and my car is programmed to turn the fans on at 180 degrees fwiw.

Then all LS1 Corvette oil temp guages must be innaccurate because water temps can go to 230 during the summer and the oil temp is still below 210.

Have seen temps of over 316 at VIR in Oct with redline 40wt racing oil , backed off a bit and temps came down , no engine issues have since put over 500 track miles on the car , . Have read on some of the track boards that 340 seems to be the max tolerable.

B.S. ! The oil is only cooled by the engine, or if it has an oil cooler, the engine coolant. If the engine coolant temp is 195, then the engine oil is at least 195. The engine oil is typically a little hotter than the coolant because the oil comes in direct contact with the pistons and other friction surfaces, the coolant does not. Also the oil is less dense than the coolant, therefore it has less cunductance when it comes to heat transfer. Now if you introduce an aftermarket, external oil cooler, then you could possibly see less oil temp than engine temp, but we're talking factory here right?

Well, at least you have admitted that you could have cooler Oil Temperatures than coolant temperatures.

Mine stays at about 185-195 under normal driving and takes a while to get up to that.

Same for me, with a 160 thermostat.
