I tried, probably more accurately misused, Wilson Combat Oil, Universal and Grease.... ....some of those are not even intended for pistols.... ....I'm moving back toward the Lucas Gun Oil... Still using WC Oil on the pistol barrels and barrel bushings...
hmmm, in most cases, no... ...but, most quality firearms, the type and quality of lubrication is not that critical, just as long as it has some lubrication.... ...then yes, I'll agree with your point... i.e. a good pistol will run just as well, with the finest and worst oil, as long as it applied properly...
The guy that posted a pic of a can of Crisco Lard, I almost quoted it and challenge someone to try it, would you be surprised a good quality pistol lubed with Crisco Lard ran all day at the range just fine? I wouldn't.....
