Most powerful springers will diesel for a few dozen shots when they are new. It is not good for them but apparently does no real damage in that time.
Weihrauch, unsure of the spelling, used to make an air rifle with a little port which you swung out, dropped a drop of ether in, closed and it would purposely diesel. Obviously very powerful and it was made to withstand the explosion so I guess it did no damage.
WD-40 makes a good drilling fluid, but it is not a
good penetrant and it is certainly no lubricant.
PB Blaster is very good.
ATF was developed during WWII to replace whale oil
as a fine lubricant which was hard to procure.
We use a mix called Ed’s Red on our weapons.
It is one part kerosene,
one part turpentine.
one part acetone.......if for a cleaner.
one part ATF.
We also mix it with pure lanolin to make
a thicker application.
The acetone evaporates quickly anyway but is
good for loosening crud.
If using corrosive ammo, spray the barrel down
with windex before you leave the range then clean
with ed’s red with acetone,
finish with the thicker mix and you’ll be good to go.
Make it up using quart measures and a gallon lasts a
long time.
