You may not have varnish. Some oils tend to "stain" the bright metal surfaces with an amber tint. I think this is a product of the dyes and additives use in the oil. Mobil 1 Tri-Synthetic seemed to do this in my cars.
Varnish, on the other hand, will be a definite coating on the metal parts, not just a color change.
