Honestly, haven't noticed the oil temp.
But just reminds me of a story. Friend of mine in high school had a 2 door Jeep Cherokee. I think it was a four banger., Anyway, he watched his oil pressure gauge real good, and that's how he knew his oil was in good shape. Until one day when the motor seized. That was the end of that Jeep.
That story has stuck with me. So I look at my gauges, but I splash a hair of Regean on there, trust but verify.
