I had by heater core (Matrix) changed because of the dreaded Silica Bag blocking the Core so the heater was not working 71,000miles I then started looking at my engine oil temperatures wondering if the oil cooler might also be blocked? Water Temp normal and steady at 90C after about 10mins driving. The oil temp rises much slower which is normal to about 90 to 102 around town with outside temps now in the 5c to 10c range If i go onto the motorway and drive to the speed limit (ish!!) within 20 to 30 mins its up to 115c to 120c range . This is with no additional load other than me the driver. In the summer I drive to France with 4 golf buddies with suit cases and golf clubs in a roof box. What can I expect ? is this already too high. Research online does not really give full ranges of oil temps fully loaded driving a speed. Advise anyone
