does it make a difference when installing new gears to use fluids such as Redline opposed to valvoline or others. Ive seen products that say they reduce temps, etc.
is it all just advertisment or does it actual make some differerance?
It's not like running the best versus the worst will make your car seem 10 times faster or something, but reduced friction is reduced friction, period. Any full synthetic fluid (mobil 1, royal purple, redline, amsoil, etc) will provide outstanding protection, and will last longer than regular conventional fluid normally would.
