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.
