275F indicated is reportedly 255F at the sump. This is just no big deal for any decent 30-weight synthetic, and if you want higher pressure than what that gives just run 40-weight. Honestly at 235F indicated I'd probably just run 0W20 street or track all year.
These cars have had engine failures with and without oil coolers. Some are so fixated on it that one guy with a cooler and 235F oil temps had a failure, and was desperate to get oil temp lower still for the rebuild! It wasn't the oil being too hot that caused failure...

I stand by what I said and as far as I can tell it's a correct statement.
Have you seen this thread ? I find more and more people trying to keep the oil cool. Running high oil temps might not been an issue but I still can't wrap my head around wanting to run higher oil temps just cause.
