Haas VF - Bijur oil pump & what oil do you guys use?

[TwinSpool]

I recently made a purchase of some consumables from Haas for a 2012 and decided to purchase their oil and sent me a quart of lube that I believe said #2 on it. I've since discarded the container so not sure the exact verbiage on the container but it sure looked like Vactra #2. Is the replacement oil extremely similar in weight to Vactra #2 but somehow different? I've been topping it off with Vactra but will switch if there's a meaningful difference.
