Actually there is reasons to run them at those temps, for one it keeps water out of the oil better and water is a direct chemical byproduct of burning gasoline. Also helps MPG a tiny bit.



All you need to worry about is that the oil temp hits 212 or higher to evaporate the water out of the oil! All the other mumbo jumbo is so the MFG. can hit their quotas. 190 stat will do that down here in the south!!
