Yes, OEM is used in millions of vehicles but it is by no means the best. There are superior lubricants. I would not say any are a 'lifetime' fluid.
Let's rephrase this quote and look at your signature block:The oem oil does the job, and approved by the engineers that designed the gearbox itself.
orThe oem dogbone mount does the job, and approved by the engineers that designed the suspension itself.
orThe oem tune does the job, and approved by the engineers that designed the ECU itself.
The oem flywheel does the job, and approved by the engineers that designed the transmission itself.
Actually not true. Many other products on the market have far better lubricating properties both while cold, and at operating temperatures, which is of course what is most important. The OEM oil is designed to work in all temperatures without major issues; it is not designed to be the best in any particular geographic region, or best when cold, etc.if you compare oem to amsoil or another top brand the lubrication properties are so minuscule that the extra wear and tear wouldn't be noticeable if you drove the car for another 20 years.
Well I Chose the amsoil due to its flashpoint and viscosity. Wanted something that'll hopefully work well on cold morning starts here in central florida, and also the high heat
So far, SMOOTH. Smooth shifts, like butta. Also the clutch peddle feel is better? Feels like it releases faster, similar to when i first had my HS RSR Clutch installed. Not sure if gear oil would even make difference in that.

People "upgrade" to aftermarket products for a variety of reasons, not the least of which is cost and/or quality. The OEM fluid does the job, but it is not the best quality, even at the same/similar price-point.
