I'd be curious as well. That can be had locally here and is a decent amount cheaper too.
I have no experience with that MT fluid, but I believe the one in the white bottle is semi-synthetic and not sure about the fluid in the black bottle. It has good reviews on Amazon
Pretty positive that the white is full synthetic
On Amazon the bottle says Semi-Synthetic, the black bottle doesn't specify
Makes me miss the warmer Southern Utah winters. I moved to Northern Utah last year and have to deal with 20-30 degree colder winters and this horrible white powdery stuff... I'm hoping the summers will be cool enough to make it all worth it, but we'll see.
I used a Synchromesh... I think it was a GM product in the past. It was good once the car warmed up but it was a thicker oil (75w-90 I think) and the cold winter's in upstate NY make it virtually impossible to shift in the RSX I had at the time for several minutes after startup. I didn't notice it's warm performance to be any better than the Amsoil, and the Amsoil was good to go even at -15F.
Good to know! yes it is a GM product. I think ill be going with the amsoil then. I store her in the winter but i rather have it just in case.
There isnt anything long term gained other then you feeling the car shift better. If you feel the car shifts fine as is now. Then dont worry about it. But if you feel the crunchy feeling most people on this thread are talking about then getting a better oil in the gearbox is gonna help
I understand that, and to be honest, so far, I do not feel any issues in our 2018 Si, and have been driving MT for quite a few decades !!
I don't know, I can't find to much information on it except that it is equivalent to 10W30. It has a lower viscosity than Amsoil at 100 degree C (7.5 cSt @100 degree C/212 F, Amsoil is 10.1). It is probably not synthetic, but I don't know for sure
