Do you have the
oil cooler hooked up on your SPF? That will have a lot to do with different readings. You really want your
oil to get up to 100C to help dissipate contaminates in the
oil. I usually see about a 10 degree C difference between my oil and water temps with the oil being the higher, under normal driving conditions. Under track conditions the oil will get a little hotter, but not much. Water temp usually runs 85 - 90 C no matter what the driving conditions are.
