Your next thermostat won’t last near as long.   My original was 25 when replaced, the new one only lasted 5-years.

So Thursday night driving home doing about 65 I see the oil temp climb from its usual 180-190 making it to 240 in about 10 minutes. I also see the oil pressure dropping to ~35psi. Slowed down and cooled down some. Get home check things out, the oil cooler is cold. It appears the oil cooler thermostat failed. Job for this weekend! Anyway, without gauges I never would have known.
