No specific numbers, but I have friend who uses thick impasto style with oil paints. At one point he was trying out cheap and expensive oils and had a studio visit with the owner of a major gallery.
The first thing the gallerist did was point out every painting that used the cheap oil paint. Now he exclusively uses Old Holland brand oils. some of which list for 300-500 USD for 225ml.
