Were those the Winton or the Artist's Oils? I forget which one is which - but one has an even pigment grind across the spectrum of colors, while the other one has more varied grinds depending on the pigment in question (think the Winton is the chunky version while the Artist's oils are the creamy...). Anywho, point being, it will also depend on the line as well.
To the
OP, more or less, yes. Any oil paint will work for doing oil washes. So will enamels. In many ways, you do get what you pay for though - and if you are looking for very fine streaky washes, you may want to look for something that is a bit more refined to avoid any large pigment particles.
In terms of the advantages of artists versus cheapo solvents...smell is a big thing. However, the exact formulation will also vary depending on what the intent of the manufacturer is. I have found that artists odorless turps (brand is largely irrelevant) are less likely to damage underlying paint. Some of the stuff from my shop though will do a number on half cured acrylics. For the most part, they are the same...just the minute variations in formulations is enough to impact how strong of a solvent they are.
