Actually,Tim at MAC 1 has his "secret sauce"....great for lubing bolt,o'ring,etc...I use Remington "REM Oil" for exterior barrel,receiver,etc...
Also,I run dry patches down barrel after 500 shots or so...if you use Crosman pellets,I'd clean barrel more frequently...they lead up barrel more because of some "coating" on their pellets...you can also lube pellets with Krytech very lightly in a tin to help keep barrel cleaner.....(all this info is on MAC 1 site)....
