ok im going over properties list of redline mtl, royal purple synchrfomax and pennzoil synchromesh for a dodge 6 speed and i dont know whats is important. But i think viscosity index is one for po, its 208 rp196 and rl171. But viscosity at 100c changes it all to rl being best at 10.2 po at 9.08 and rp7.7 whats inmportant here po says it meets ms9224 and rp implises it does too any thoughts
