What is the typical temperature range of motor oil in day to driving with a H/C, (baby cam)- LT headers, LS1 suppose to be? When it is 65* outside temperature, my coolant temperature stays solid at 194.* My motor oil temp varies dramatically between 210* to 222,* is this normal?
Oil temp fluctuates a lot more than coolant temps do. It all depends on how hard you're running the car. 250+ isn't unheard of, and still falls in the "normal" range.
Synthetic oils are stable to about 300, but if you find you're consistently running over 250, it's time to invest in an oil cooler.
