I'm not positive that Teflon won't clog the wicks, so I wouldn't use it in a wick situation. Tri-flow oil does leave a residue in my syringes that has to be shaken up and mixed in or it clogs the syringe. I don't know if that's the Teflon or the paraffin or some other additive though.
I'm really not a connoisseur of PJ. I bought probably my first batch of it in easily 15 years tonight and that's because I wanted squeeze tube for filling some syringes for my VM maintenance class next week. The 15 yr old tub isn't empty. Yeah, I'm lazy and I paid the surcharge for the laziness.
I think it might be worth trying to test to see how they melt comparatively and use the one that melts the most to your satisfaction.
