Amsoil VS Redline MT-90
Which one should I get for my 4th gen. I have a B&M shifter and I am going to have Jeff @ Maximum Tuning, install a Spec1 clutch kit w/ a Fidanza Flywheel. Which tranny fluid should I get? All opinions welcome!!! Thanks

Shifter doesn't care about the fluid. Fluid doesn't care about the shifter.
If you buy the Amsoil, get the MTG 75w-90. It's a true GL-4.
It's also equivalent to Redline MT-90, which makes this poll kinda pointless.

I'm currently using Mobil1 gear oil (sorry, I forget the weight) and it works very well. Nice feel and smooth shifts. Goes into first gear easier. I disagree with dgeesaman. I notice a different feel with better quality fluid, especially in cold weather. In Chicago winters I couldn't get my previous cars to shift when cold on dyno fluid. Synthetic makes it easier. Not really a concern in SoCal, but there is a more fluid (punn intended) feel to the shifter. Mobil1 is not GL-4 though so some day soon I'll switch to a GL-4. Remember GL-5 is not better simply because it has a higher number. If you can, get a true GL-4.

The smell of the oil? You can only smell if it the oil leaking. The smell is mostly from the EP additives. The interior of my car smells a little like gear oil, but only because I haul around trannys and tranny parts in my car. You can't smell anything normally.

where do you gte amsoil from i have redline mt90 and sometimes its alil ruff to get into gears i want a gear oil that easy to go into gears cold or hot any info would be greatly appreciated thanks

i just recently changed over to amsoil from redline...
with redline the shifts are easy and hardly notchy till about 20-30k miles and then it starts to stiffen up, becoming more notchy as time goes on.
with amsoil things are notchy from the start. depending on how short your shifter is, shifting can be alittle more challenging with this fluid.
i've read (in the stickies) the amsoil protects better so i'm sticking with them. hope this helps...

Yes, MT-90 is ideal for that tranny.
Ethnic6, yes, manual transmission use gear oil. It should be changed every 60k or so. If your maxima manual tranny has high mileage I'd suggest even every 30k, since they see so much bearing wear.

what about lsd limited slip trannys they used a different oil? or the same?
75W90 Gear Oil - the preferred product in nearly all car and light truck differentials, both conventional and limited-slip. 75W90 is preferred for most racing applications. It contains friction modifier which is recommended for limited-slip units. 75W90 Gear Oil can be used in many transmissions and transaxles; however, other Red Line lubricants have better frictional properties for rapid synchronization. Exceeds API GL-5.
In racing applications, the lighter fluid will allow for less drivetrain power loss, but requires more frequent changes. For racecars doing a lot of high rpm launches, diff abuse or wanting longer change intervals we recommend the Red Line Heavyduty Shockproof Oil.

i was just at a site that sells redlin oil they have 2 types
RED LINE MT-90 is designed to provide excellent protection and improved shiftability for manual transmissions and transaxles. MT-90 has cured the problem of hard shifting in numerous transmissions which have notoriously difficult shifting. The secret to its success is two-fold. First, it has the appropriate coefficient of friction for most manual transmission synchronizers. Many gear oils, engine oils, and ATFs are too slippery for proper synchro engagement. Secondly, the viscosity characteristics of MT-90 allows proper shifting over the entire temperature range which the transmission will experience. The synthetic base oils used have a very high viscosity index which provides relatively constant viscosity as temperature changes. MT-90 is a thicker 75W90 version of MTL. The shear stability and oxidation stability of the MT-90 oil is excellent, thus the physical characteristics will change little with use.
MT-90 is a 75W90 GL-4 and also satisfies motor oil viscosities SAE 10W/15W/40. The additive chemistry used is non-corrosive, so even though they will provide GL-4 performance, they will not corrode synchros or bushings.

I had Mt90, and switched to MTG. They are both pretty thin, but the amsoil is thinner, at least it pours thinner. I cant comment on feel because I swapped trannies. I have also mixxed mt 90 with MTL (which is thinner) and it was pretty good for cold climates.

kinda late in the thread bu i know what you mean by the horrible smell, when i was trying to find out wtf was wrong with my car, later finding that my transmission blew, all i could smell is that nasty gear oil smell. After a while of it being all over you, you learn to love it.

I find that the pour of gear oils depends greatly on temperature - if you're doing it on a day where the temp is any less than 70F, it helps greatly to get that oil warm to 70-80F or more.

i love the smell of mt-90 and i will swear by it. i know that immediatly in both my maxs i noticed really smooth shifting, and i was able to downshift into first without too much force at 25mph vs 5mph. now im sure thats hard as hell on the synchros so i dont do it, but thats one thing i noticed
