Here in South Florida (95+) with the stock cooling setup I would regularly see 220 - 225 oil temps. After cleaning radiator of dirt/debris, flushing coolant, and adding a bottle of Redline Water Wetter the oil temps never go over 205 - 210.

that is right where you want to be. it is my poinion that guys runnung above 250 at the track are the only ones whou would benefit fron an oil cooler. oil temps in the 200 and less all the time are not what you want. once again just my poinion.

Temps you guys are seeing aree VERY low regarding the use of a LS1/LS6. You get a warning message in the DIC when you see 300 degrees. Head over to the autocross/roadracing forum and research this issue.
I typically see 285 running at Hallett, a road course. There is discussion that once you see the temps I'm seeing it might help to get a cooler. Many say it's not an issue at 285, others disagree.
The temps you're seeing are VERY acceptable. Don't waste your money if all you do is street driving.

Anyone ever run one of these?

knowing the right numbers is key.... hotter oil produces more power... too hot causes thermal breakdown and shear..too hot is 280.
if you can keep both the coolant and the oil in the sweet spot, the car runs right.
Take it or leave it....

Leave the stock thermo in the car and clean the radiator inlet and don't worry. Your temps are in the correct range and will not adversely affect your engine. I have a Ron Davis Racing Radiator in my Z with built in engine oil cooler and the stock thermostat. Before I added a thermostatically controlled oil bypass valve my coolant temps would run at 200 and oil temps would run at 230 after 40 minutes of WOT on the track on a 85+ day. With the 180 degree bypass valve which determines the amount of oil flow through the oil cooler the oil temp runs about 265 now and the coolant temp has increased about 5 degrees. The setup includes a remote mount oil filter so I am running about 8 quarts of oil when I add the extra quart for the track.
By the way when I ran the stock cooling system the coolant would hit 230 and I saw 313 on the oil (no alerts from the car) under similar situtations.

But I am hitting 270-285 oil at the track......2hrs every 5 weeks or so. I have large radiator with EOC. Should I stay with Mobil1 5-30. Should I be saving up for new engine ????
Thanks in advance for your input........
