OK, this probably has been discussed before so I'm guessing the answer is right there in front of me, but here goes;
Can different octanes of gas be mixed?
My VDub actually runs best on 91.
My most convenient stations sell 91 and 93, both for the same $$$.
What if I mixed Station B's 93 and 89 octane for an average of 91? and a cheaper overall tank? Is that useable or do they not mix?

Also, I know that the savings are hardly worth the time it would take to make two separate transactions, but still I've been considering it.
Thanks!
