Yeah, that's what I said. Just think of what it could do for a machine gun.
But, my foty doesn't have a filter.I really doubt that the internals of your gun will be subjected to the constant high temps/acid levels and particulate contamination that your crankcase sees. Just sayin'...
I lost two $850 hydraulic pumps to Mibile1 on my ExMark mowers. It was recommended by the factory. Switched to Amsoil and haven't had an issue sense.
I use sand. I seems to work well.
I may have overlooked it, but I have never seen either Royal Purple or Amsoil at my local Walmart, or Auto Parts Store.
Advance Auto carries Royal Purple. It's $10/quart there but that should last the average person for years. I think I saw it at the NAPA store near me, too.
You can order it online from Jegs for less than $8/quart with free shipping and handling if your order is $30 or more. I buy it from Jegs by the case and it usually shows up a day or two later.
I agree with you, though. For the average gun, any type of synthetic motor oil should be plenty good enough. Even synthetic blends like Havoline should be good enough.
I use Mobile 1, but recently have been told that atf (automatic transmission fluid) works better. I haven't tried it yet.

The Citgo is probably hydrocracked mineral oil (Group III). Group III is not a true synthetic. Mostly just marketing fluff. High-end stuff like Amsoil and Royal Purple are true synthetics consisting of Group IV (PAO) and/or Group V (Esters), with better viscosity index and low volatility compared to non-synthetics. Low volatility is why your bike didn't burn off the Amsoil.
Probably because Mobile 1 changed from Group IV PAO to Group III mineral oil the better part of ten years ago. I change the oil on four vehicles and noticed the difference right away. Instead of draining out thin but dirty, it drained out thicker and reeked just like ordinary, low-rent mineral oil. I switched to Amsoil SSO and then to Royal Purple a couple of years later. I have nothing bad to say about Amsoil SSO.
The Specialist "Long Term Corrosion Inhibitor" label.
I dont suggest any of it for internals or for moving exterior surfaces. Its just for static externals.
Do you slather it all over your big Johnson?
