I use VP C85 instead of pump, and love it.

Most of the problems with pump 85 have been solved using the C85.

Has lube, and corrosion inhibitors in it, draws less water, and is consistently blended. Only down side is it's twice the cost of pump, but half the cost of a good race fuel.

Typically I burn less than a half gallon per pass accounting for warm up, and to and from the lines in total for the day.
