Yes! Unless your tank is not completely dry when you fill up!!!

My plan is to drive down with enough gas in the tank to have 1gal to spare. That should get me to about E68.

Why does this matters in your case?
It matters (sort of) for a few reasons:

I would prefer to have an high enough E on the first fill-up to get full HP. (Yeah, just personal preference.)

I also believe the PCU will do some learning on the first tank of Exx. I have no hard evidence, but I would expect the PCU will watch, adjust and remember. (Maybe I'm expecting too much.)

If I could get a very high E (like E85 for real) I can cut it with Sunoco 100 I get at the pump locally, I figure that would a very convenient way to make a nice and safe race fuel. (And relatively CHEAP, the way I like it! :ROFLMAO:)

I don't like to dance close to limits, if I need 65%, I aim for 70. (Yeah, I know...)

Thanks for the link to the calculator, just this morning I made a xel spreadsheet to do just that! :) :ROFLMAO:
