If the current doesn't look bad, and pan shows nothing out of the norm, then I would run it and do a drain and fill a few weeks into the season. The gold color could be anything from a specialty fluid to a hydrastat fluid. We did a track side build once and got fluid from like 5 different people, (each was different brand) Royal Purple, B&M, Type F, Amsoil, but we gathered enough to get it full, and he raced it for 2 seasons like that.
