The way I understand it, you want a fine balance, but it only seems to work for me on longer road trips. You want an oil temp warm enough for any moisture (H20) in the oil to evaporate and go away, but not so hot the oil loses it's lubrication & cooling properties. Apologies to Jack, but all to often, my problem with a box stock '72 S is to get the oil temp up enough to circulate through the front radiator cooler. I understand that's around 180 degrees? Going to Cambria last May, while others without the front radiator were getting nervous about oil temps? Through 95-100 degree California central valley heat? I never got past 220...
A track day, years ago, I saw 235 or so...briefly. Yep..this is blatent bragging!
