Just meant more engine wear from sub 170 degree than 210+ (OPs concern).
Yes I used to block the air cooler in AK winters with an aluminum plate. I was never as concerned about low temps engine wear, though there is a lot of internet data out there on that subject. I don’t necessarily buy it all. As per mpg, nothing I could care about less

Here is that original thread:


It got a little contentious but ended with Kumbaya.

There was a lot of info in that thread but everything is summarized well here above. @Patriot says run synthetic and leave your high temp worries behind. Very true. The summer/hauling EOT that a BPD air-to-oil delivers is well within the range of synthetic. Follow his lead on this.

@jetjock15 @kcoyner and @ChrisSki all mention not falling into the trap of believing that perpetually low oil temp is good. There have been people on here bragging that their oil temp never gets above 140F. Don't be that guy. A consistently achieved EOT of 200 or more is a good thing for oil health. If it isn't happening due to cold ambient conditions, make it happen. It's not difficult.

...and @wyowolf 's observation is good for planning purposes.

That is pretty much the whole deal, IMHO.
