To balance out the last spectacular tank, which I have a suspicion didn't fill all the way.

I really think my gas tank has some sort of back flow valve which automatically cuts at 10.4 gal or there abouts because its a very common number I am seeing when I fill up.
I really really need to get a scanguage.
I had my stock airfilter back in for the drive home today, don't think that could have made the difference on the drive to the gas station.
K+N is sitting in the garage re-oiled and will be going in asap.

I don't know if this tank corresponds directly to the recently cleaned air filter... (it was probably overdue)
I'll see what the next few tanks bring.

I guess I'll just anticipate and put 45% instead."
