The test was done on a car that was being used to test all the oil filters... so I would say the oil was pretty clean.
Last night I went out to the garage and popped open a quart of 20W-50 (which is what I am running in my Subaru Legacy) and poured a little onto a dish. I then used that lube my slide rails on my Beretta.
Very smooth... Very smooth indeed.
Wait a sec.
Not fair.
My Beretta was very smooth to start with.
I wish I still had my last Springfield 1911... it's slide was "Less than Smooth" and would have been a better test platform.
Of course the only downside to useing motor oil to lube is that you still use other products to clean... Unless your of the "Monster Garage" camp and use gas or carb cleaner to clean your guns with already... I know "PB Blaster" does good things.
Oh, PB Blaster... great for unsticking your nuts right? Well, if your working on engines and stuff and not wearing mechanics gloves... your going to get your hands and arms all greasy right? Give your hands a shot of "PBB" and rub that into the grease before you go inside. Then when you hit it with the Lava or Orange hand cleaner... all that grease just washes right off easier than anything.
One automotive lube that really sucks... it's stuff you get at Walmart in the automtive section. White Lightning. I think it's called. It's a white colored spray on grease. It's pretty worthless in my opinion. Slide rails? Don't even think about it. You'll have to use break cleaner to get that crap back off.
