Hi,
I second Ron's comment about making best power at 210 degrees. I ran my Pontiac's 10's of thousands of miles at 210 with no appreciable cylinder wear. I wouldn't be concerned and would actually want my engine to run near 200.
Remember if your
oil doesn't get somewhat over 212 degrees, the water won't crack out of it and you will accumulate moisture in your
oil. Not good for engines that don't get run everyday.
