according to several gearbox manufacturers. (industrial machinery gearboxes) they say if you use synthetic oil you can withstand 25% more torque. Better fuel economy, although that is hardly an issue. that seems enough for me...disadvantage would be the extra $20 you would spend on it. Personally I don't care about $20.
