It might be because you are using a higher viscosity oil. Were you
using 80 last year? Changing from 50 to 80 will definitely cause a
noticeable increase in oil temp. The rings in the new cylinders
might have slightly higher friction and you don't say how many hours
you have on the new rings - after a few hours, though, I would expect
this effect to have gone away. I can't remember if these engines
have an external oil cooler or not, but this is another source of
problems as they do eventually plug. If it has a vernatherm that
would be the first place to look.

I was using Aeroshell 100 last summer - started using multigrade in the fall
and changed to the Aeroshell 80 (April) mineral because of the cylinder
work. Now have 26 hours since the cylinder work. I would have expected the
rings to seat by now. This 0300D doesn't have an oil cooler. Not sure what a
vernatherm might be.
Thanks
Gary

I have an O-200 and my AP had me run mineral for the first 50 hours. The
temps did come down after about 40hr. He said it takes at least that long
for the rings to really seat.
