Compared to the heat, pressure, torture, and continueous use that auto engines and wheel bearings are exposed to, any lube that works well in them is certainly suitable for a firearm that is used only occasionally in comparison. Now if one chooses to store their firearm in a salt barrel full of pickle juice--good luck with any product.
While my gun cleaners and lubes tend to be the choice of product at hand, I've never experienced any lubricant issue with any name brand oil or grease--regardless of if it was packaged for guns or autos, save for one WD-40 rust episode. That product no longer graces my firearms.
