Which type and how much butane do you use to make BHO?

[Gemdaddy54]

When making BHO what type of butane do you use, how many times has it been refined, and how many ounces?

Is triple refined good enough, or do I need to find a more refined one?

I saw a 12 pack of 3 oz cans of colibri premium butane for $75. Seems pricey to me but I don't know how much it usually should go for. Plus if I need to use 3 or 4 cans I don't think it would really be worth it.

I would use Vector..it's 5X purified and is the bomb..Works well. 5 bucks a can
