WARM --OR RATHER HOT--, YES. IDLE, NO. TALKING ABOUT STEADY STATE EQUILIBRIUM
AFTER AT LEAST HALF AN HOUR AT 60 MPH+.

MY PRESSURE GAUGE IS A CHEAP NO-NAME BRAND AND I DO HAVE
SOME DOUBTS
ABOUT ITS CALIBRATION/ACCURACY. MY POINT, HOWEVER, IS THAT SYNTHETIC
OIL APPEARS TO HAVE A RATHER STABLE VISCOCITY. ON A COLD ENGINE, BOTH
OILS GIVE ABOUT THE SAME READING, BUT ONCE WARMED UP, SYNTEC DOESN'T
DROP AS LOW AS, SAY, 10w-40. tHIS IS NOT A CONTROLLED, SCIENTIFIC
EXPERIMENT, THOUGH.

WINTERS _DO_ GET QUITE COLD HERE. DO YOU LIVE IN A NICER CLIMATE?

HEAT SEEMS UNAVOIDABLE, THAT WHY I USE AN OIL THAT'S LIKELY TO WITHSTAND
