Jonathan Linton has done a series of tests to see how much white oil paints will yellow over time.
He tested 40 swatches of paint from 11 different manufacturers over a two year period.
The result: some whites turned an alarming lemon or orange color. The cause, according to Mr. Linton: “The culprit seems to be the vehicle (or binder) used. Since safflower oil yellows less than linseed oil, I'm sticking with whites made with safflower oil.”

Thanks, Jonathan.
