I've seen several cars run mobile 1 their entire lives and they are always coated in yellow varnish, including my own 2001 galant. I'd recommend staying away from it for that reason.
Mobile 1 is factory fill for some very impressive and expensive motors. I think if it's "good enough" for Porsche, the high powered Benz AMGs, Aston, ect, ect.....it's just fine in our Audi's.
Yellow varnish? Be more interested in the life and other environments of those cars. Far from scientific methodology there.
I don't touch anything Shell, but the first most important step is to use oil that meets the required specifications of the manufacturer, not just what you like. I generally stick with Mobile 1 and Castrol if I can, and have not had to deviate yet.
