Default How hot is too hot?

Today the air temp was 97. Coolant temp was 233, oil temp was 253. Stop and go traffic, running the A/C, and 70% oil life left.

Is 253 oil temp acceptable under these conditions?

Yes, it's completely normal under those conditions. I frequently see the same readings when going from 5,200 ft to over 7,000 ft altitude on busy tourist clogged roads through northern AZ in spring/summer.
It's scary and you did probably reduce it somewhat by turning on the a/c which activates the second fan. That helps bring the coolant temperatures down which in turn brings the oil temperatures down.
This is why we use synthetic oil/filter in our C5/Z06 cars...

I hit about 290* while on the track one day. I got off shortly thereafter though as I was getting nervous of that 300* mark in oil temps. You gotta love Mobil1.

There probably isn't a topic that hasn't been asked/answered in C5/Z06 at least a dozen times (or more)...search would save a lot of band width...

Last year in the summer, while on track 290's were common, and 305 was the high.
