Your readings are decent.
What most probably happened is you got a little bit of heat in the rings while cranking it over.
That raised the readings.
Run it.
Getting any snow? It just started here
Small chance of snow, but not expecting any accumulation.
I had the engine warmed up good before I checked it. Let it idle a while and drove it around the yard. If anything it might have been cooling down some by the time I did the last couple readings. It's only got a couple hours run at most on the new rings(mostly idling), so will see what it does with more run time. Takes a while to break in when it doesn't leave the driveway.
