Yellows slightly more than the cold pressed linseed oil. A good job by Grumbacher.
Today I'm ready to photo the paint tests of 1995 for an 18 year test, the best non-yellowing mediums are:
wax, damar, poppy oil, Venice Turpentine, cold pressed with damar and cold pressed linseed oil.
Stand oil didn't make the grade, maybe it wasn't made with cold pressed, they don't tell you on the label. 10-15-13, I shot the 1995-2013 oil yellow test today, it's maybe 10% more yellow.
