Heavy duty lube might be too thick and muck up the seals. Just my guess though.
It might not just mess up the seals, if it gets vaporized with the expansion of propane, it will get carried into the gun and tar up the inner workings of the GBB. I say strip the whole thing, clean it out, use a lighter silicone oil and see where you're at.
