5 gal of Swepco was given to me by a Porsche shop in Denver 15 years ago. Before that synchos would last from one to five races max in our GT-2 Rx-7. After the switch, we never had any more problems, and replacement was only at overhaul, when necessary of the tranie. Porsche people really like it, to a point of Swepco, or park it. As to the type, well I put it in to smaller cans, and dumped the orginal can. Sorry. Talk to Swepco. I'm sure they know what the racers use. Its like that black lube that Ford used to sell for Detroit Lockers. Nothing else worked as good and now Ford quit selling it. I'm sure Swepco could cover it though.
