BUT, depending on how thick the TR6060 likes its lube, dare I ask if better or more consistent results may occur using the Amsoil or Pennzoil due to their higher viscosity indexes than the Royal Purple Synchromax (remaining a more consistent viscosity through the temperature range)? These oils are thicker, and I'm not sure if the TR6060 prefers a thicker or thinner oil.
The Royal Purple Synchromax tests as the thinnest of all the lubes shown, does anyone know if that's what it prefers? Not trying to reinvent the wheel here, though it may seem as such. Lol  |
From what I have read, the TR6060 is designed for ATF i.e. thinner than regular gearbox oil, probably why so many people prefer RP synchromax
