I've told by another well respected rotary expert that the REW is designed
to run at 203 - 212F, that oil temp should be kept below 240F, and should
never regularly go over 248F. Everywhere I go I hear different numbers for
these limits. I'm using 5-30 Castrol Synthetic.

John, 

 One aspect of the disparity is the problem of where to
measure the oil temp.  Mazda does it at the oil pan.  I
believe that Lynn is doing it at an adapter block where
the oil returns from the cooler to the rear housing.  It's
going to be cooler there - and more relevant to the temp.
at the bearings. 

Dale R.


Dale, Mazda does not measure oil temperature anywhere. The cars don't have
oil temp. gauge. Only thing in the pan is low oil level sender.
Bulent

True and false.
There is a temp sensor in the oil pan. However, it's a "low" temp sensor.
