the oil you use really depends on your gun. when my coker was a single trigger i started using goldcup(summer time). when winter time rolled aroudn and the weather started getting a bit nipply out the gold cup actualy thicked, almost gelled. the trigger frame and for that matter the rest of the pneumatics did NOT take well to this. PMI, in the blue bottle, is a synthetic based oil, which supposedly has some type of antifreeze or anti gel or something. in any case, it never gelled up on me. i save the gold cup for my tippman.
as for vaseline, no. just no. petroleum based products genearly eat rubber. this would be bad for your orings.
dude, do you know whats in car oril, and your gonna put that in your angel? stick to love juice, it was designed for your gun for a reson
angels raryly need oil, but a couple drops now and then of love juice in your reg isnt a bad ide
smart parts,,, you have don corning 33, ie the pink ****
i dont know anybody else who makes their own oil, but im open to hear about em'
and just remove any thoughts about vaseline and your cocker. keep it for your dick
