Since '15 it's been Sunoco. I assume it will continue to be Sunoco next year. Sunoco branded, anyway.
Makes sense. Ya I wouldn't think you could go into a Sunoco station and pick up a gallon of nitromethane or Green E15.
Is it still true that the Sunoco stuff is ~$1428 for a 42gal drum but the same 42gsl drum from Don Schumacher is $1008? I had to dig the find an article about the prices from earlier this year.
