I have noticed my newer engine is running hotter oil temp than the older one. Used to be 190-200 max. now its going up to 220-230.
Anyone can say for sure what max norm opr and also max safe temp should be? Charlie Heathco

You did not mention which engine you have? Most engine manufactures
recommend 245 - 250 Deg F as the Max point. This is also the accepted point by oil
manufactures as well.
You are correct you will be seeing higher oil and CHT's with a new engine, it
is breaking in. Keep your climbs shallow, air speed high and the RPMs high
also. Don't baby the engine, oil consumption should stabilize in 50 hours or a
little less. Change your oil after the first 10 hours and then at 20 hour
intervals until oil consumption is stabilized
Your 220 - 230 Deg F is quite normal especially for this time of year.

A PS to my previous post...
You did not mention what the CHT were. If yo have a gage keep them LOW ...
Lycoming use to say 500 Deg F, they recently went down to 450 Deg F, I have my
limit of No Higher than 435 Deg F.

Is this with the same oil temp sender and indicator as the old engine? Has the oil temp indication system been calibrated so you are sure it is telling you the truth?
