Vp is really good, and they've been around a long time...so I'm sure extensive testing has gone into it before they decided to go ahead and announce they're gonna sell it.
I'm sure it's gonna have a shelf life of some kind, though they haven't mentioned that yet...it can only be good for so long, so I'm just guessing, but I'm thinking it'll need to be used within a week or so after purchase.
Though I have to run 75% c-12 in my 500, I still don't go through a 5gal bucket that quick...I typically go through one every month...so it probably won't be good for me.
But again...we'll see how it does once it's been out for a while, and see what riders say/think about it 1st.
