I know you should keep the rpms under 2500 untill the oil gets up to temp, but my commutes to work are a bit short (30 minutes). Unless Im in traffic the car usually only gets up to 203°F. I do make sure to get the car past 212°F on the way home. Is it okay for me to step on it when the oil temp is at 170-190°F? What is the ideal temp for having some fun!

175 + is ok

I agree 175+ is good. I noticed with my car around 110 is when the piston slap noise goes away, so I keep things real gentle until after 150.
I never really noticed the piston slap from inside the car until I install sound insulation in the doors and back of the car.

Absolutely OK! If you're seeing only 200°F under spirited driving, you're doing fine. Oil that is too cool can also cause problems. The LS7 in my C5 saw 195°-200° during freeway cruising, and rarely saw 220° during, uh, performance driving. This is with a B&M 70266 Super Cooler

It’s fine, 220-240 is probably fine, and it shouldn’t get that hot unless you’re hot lapping it. I called it quits when mine saw 260 at an HPDE, guess what, my car is fine, that was 2 years ago. I’m going to try 5-40 oil, and overfilling it a half quart at an HPDE, which I didn’t know your supposed to do, if that has no effect, oil cooler is in my future budget. Stock car, normal driving, you’re fine. I also have an auto trans with 3.73 gears and 3200 stall, plus trans cooler and I saw trans temps of 225-230 at a peak, which is fine, manual trans cars probably see 250 degrees and there fine, trans cooler would help.

moral of the story, your car is fine, keep driving those C5’s.
