FE Technical Forum / Re: When to pull an engine for health check and oil temps on long highway driving

220*F for oil, or water temps is just fine....but getting up there.
Many choose temps in the 160-180 range and that is not ideal for many reasons...too cool.
But even 235*F is okay for one of these engines.
Not to hijack the thread, but I have read many conflicting opinions on the 160-180 topic. Lots of people say this is too cool, many others say it's fine and that they've never had an engine wear out prematurely for running temp in that range. My engine was running in the 210-215 range with a 180 stat in the first 100 miles (90-100f southern summer days), but I altered the grill for better airflow and now it sits happy in 178-182. When I was in the 215 range, it dieseled badly on shutdown.
Just curious what your thoughts are on the 160-180 being too cool.
