Sort of. I mixed up a batch of Mobil 1, Mobil 1 ATF and a bit of STP years ago and am still using it on most anything. It makes a good cleaner too. For 1911s though, I like to use a bit of SlideGlide on the rails. I sometimes do that on CZs too, but for handguns, I mostly just use the Mobil 1 concoction. For ARs, I like Slip2000.
