I w ould say use the losi oils because when you need help on diff setups the team is basing that off losi oil. All the oils are different brand/brand. It's not a huge deal though.

At $6 it's only a few more than AE. I'm not positive but it seems like my losi tubes have more oil than AE bottles. Not 100%.
