I’m not sure that image will show up, but one strip all the way across both oil and coolant radiators adds about 20*F to both. Often the cruise oil temperature will go up to 190*-205*F…excellent running temperatures. If it’s a bit cold, I might add part of another strip across the radiators, or even tear a little bit out if the temps have risen a bit. Many people prefer to use the aluminum tape, which works well. Duct tape can easily fly off and Gorilla Tape leaves too much glue residue in my opinion.
The danger in adding tape is restricting cooling during the critical climb out phase, so I don’t use tape above the OAT of 60*F. Watch the EGT’s so they don’t go above 1700*, and I try not to go above 1695*F. Oil temps a little above 230* don’t hurt anything, but I back off at that point to keep below that temp. Coolant temps never seem to get into the yellow or red, but I often turn on the heater, blower and air vents to drop those temps about 5*F.
Good luck and experiment to see what works for you with your climate.
