Add new fluid in solidworks flow simulation

Hello,

Im looking for some help for add a new fluid in the engineering database, i had attempted this a few times but it doesnt seems to work, i want to add ISO VG 68 oil and is hard to find the proper parameters, am using this in a heat exchanger study and the thermal propeties are important. Any help would be nice.

Thank you
