VP has a high pop-off rate (ie., unstable). I've had Sunoco laying around from one year to the next with no issues.

I think many of the 'new' names in the fuel business are offshoots from when the Torco empire crashed. I found Torco to be very similar to Sunoco. Good fuel, and stable.

Remember when testing different fuels you may need to change your jetting. Different fuels can have different sized fuel molecules, changing your mixture.
