Hard to say, itbdoesnt say the weight of the oil (the thickness)
For basics one would use a light weigh oil for adding to their propane. For gbb and gbbr lubrication of moving parts I personally use ultra slick synthetic. But there are many options.

The top one for your propane or for the blow back unit and such. And the ultra slick comes from crappy tire.
