Well I just switched to Amsoil over the weekend.

Man Amsoil is the best! 75w-90 althought like 15bux a quart, but the best stuff....

I went from cheap gas station stuff to Red Line Heavy Duty Shockproof to Redline MT90 and hands down Amsoil pwns all of it. Shockproof was bad cold shifting just like the MT90, but Amsoil... is unbelieveable cold shifting was not a factor....

I just really suggest it. Most people say stay away from Royal Purple and after using their engine oils, Amsoil Signature> Amsoil > Redline > Royal Purple > Mobile 1 = Castrol GTX > Valvoline.....

Just thought you guys know since there was a couple of discussions on this.

JRas · 02-02-2009, 04:34 PM

I'll have to try it next time

I used some Redline MT-90.. wouldn't really recommend it though

clark · 02-02-2009, 04:42 PM

yeah i used redline mt-90. i'm honestly not happy with it right now.

i'm gonna try amsoil then.

thanks for the review.

420sx · 02-02-2009, 06:43 PM

wow guys. i ran mt90 for years in my track car and i LOVED it. smooth shifts, last a while. shockproof is great if you track your car. redline mt90 is one of the best out there for SR/KA trannys imho. never tried amsoil, just couldn't justify the price tag. im glad you found something you like more though

it's good when warmed up, but when cold, it could be better...

KA240SX808 · 02-02-2009, 07:03 PM

I'm using the Royal Purple Tranny oil and not real impressed w/ it, feels just like it did w/ what I had in it before, what ever that was

*slider2828* · 02-03-2009, 12:44 AM

Yah cold shifting with Redline is pure crap.... Its just too bad cause I love their engine oils, but I changed over with Amsoil, best thing for a tranny ever!

I10cruiser · 02-03-2009, 02:12 AM

how long do you guys keep royal purple in the tranny before changing it?

dex · 02-03-2009, 07:26 AM

stoopeed question... how many quarts do you need? =)

Monooxide · 02-03-2009, 07:55 AM

2.5 Quarts for SR transmission.

If you like Amsoil transmission oil so much you should try out their engine oil too.

I personally run Rotella 15W-40 Diesel oil.

dex · 02-03-2009, 07:59 AM

Thanks... but... diesel? what who why?

240trainee · 02-03-2009, 08:17 AM

It's just oil, but the weights are a good compromise between heavy and light weight automotive oils.

and I think it has less detergants and shit in it, I could be wrong.

420sx · 02-03-2009, 08:45 AM

its really cheap too

With new emissions standards oil companies have been asked to lower the amount of certain chemicals/compounds in their oils.

However the Shell Rotella has kept the highest percentage of these detergents by over 200-300% more.

- What is Triple Protection?

Heres more information on the anti-wear chemicals such as ZDDP that they still use.

Shell Rotella is one of the leading suppliers of oil for turbine engines, I know the kind of abuse they go through and it requires a very decent oil.

*slider2828* · 02-03-2009, 09:18 AM

In generally tranny oil doesn't get changed for a lot of miles. The FSM will tell you but I think like 20k miles or something if not longer. I dunno about Royal Purple, their gear oil felt just like any other oil except at a premium price. Their motor oil I would say is better than Mobil1, but has the same longevity as Mobil 1 which is liek 1500 miles on a 350HP SR.

I use Redline Egine oil which is 1 dollar more than RP and Amsoil is about 2 and Amsoil Signature is like $3.50 more than Redline. Personally Redline performs well as an ENGINE OIL. But Amsoil Tranny oil is LIQUID GOLD....

Just like this guy

Matej · 02-03-2009, 11:10 AM

Hah, I run the same oil in my transmission that I put in the motor, 10W30 synthetic motor oil.

You serious? But during certain conditions the thing will heat up and turn to water like crap... reference to tranny

Matej · 02-03-2009, 12:00 PM

Yes, it's been in there for about two years, haha.

*slider2828* · 02-03-2009, 12:30 PM

Wow livin on the edge....

Dousan_PG · 02-03-2009, 12:33 PM

not really
most daily cars dont have the trans oil changed for years on end
sure it probaly should be changed but its not terrible if it hasnt been

anyways
i always use redline MT90 on my 240sx transmissions and with great success.

karl wasabi · 02-03-2009, 12:33 PM

I can never tell the difference when I change oils. I've run MT90, generic shit, Torco, and now I'm using Royal Purple. Can't tell the difference. LOL.

SoSideways · 02-03-2009, 12:39 PM

Redline MT-90 in my tranny for the last 2 changes, and the last time I changed the oil in there was.... maybe 2 years ago? hahaha

I already bought 3 qts of Amsoil tranny oil back when I was doing their "preferred customer" program, but never bought enough of their oil and stuff to justify keeping on it, so I just let it run out... haven't bought anything from them since.

But yeah, a buddy of mine put some Amsoil tranny oil in his S2000 and said it was the best stuff ever, not that he has tried other stuff, so I have no clue.

I'm about to change all my crap out though... maintenance day coming up...

coww-cho!!!!! · 02-03-2009, 12:47 PM

when i got my car it shifted horrible then i tried lucas tranny fluid and i love it so far havent tried any other

To be honest I was pretty sure my transmission was going to go out soon, it was starting to grind and sometimes wouldn't shift into 1st or reverse, plus it has a leak. So I stopped worrying about it and instead of topping it off with transmission/gear oil, I just started topping it off with motor oil since I'd always have some left over after an oil change. I assumed the transmission would be done for soon anyway.

Surprisingly, it's two years later, and my transmission functions better than ever, no grinding, and shifts perfectly, haha.

However, don't get me wrong, I didn't just decide to pour a random fluid in there. I started doing it after I found out that many transmission fluids are 10W30 or close, and even some race cars are running motor oil in their transmissions, so I'm guessing it can't be all that bad.

g6civcx · 02-03-2009, 12:54 PM

Borg-Warner T5 calls for gear oil or ATF. I run ATF.

Om1kron · 02-03-2009, 02:28 PM

i'll give amsoil a try on my fluid change.

DeadlyZ33 · 02-03-2009, 02:41 PM

I highly recommend Motul transmission fluid, some of the most expensive I think but I noticed an improvement switching from mobil1. It is supposed to be good for smoothing out notchy feeling trannys like the z33 has, shifts like butter now. I also believe its recommended by subie owners because their trannys are notchy too.
Plus nissan uses it in all their race cars so what the hell.

racepar1 · 02-03-2009, 02:41 PM

I use neo 75w90HD or neo 75w90RHD. The HD is about $40/gallon or so and the RHD is about $80/gallon or so. I LOVED the RHD, I have the HD in it right now and I don't like it so much. I'm gunna switch back. The royal purple tranny oil is quite good as well. My buddy switched from the NEO to the royal purple in his trans on his XB and he said that it shifted a bit smoother. The royal purple synchromax fluid is dope if your trans calls for low weight fluid, like ATF.

As for motor oils the diesel oils are the best, especially for motor break-in. They have a LOT more detergents and suspend particles much better. For break-in I would run a 15w40 non-synthetic diesel oil and after that I would run a 10w30 synthetic oil. Synthetic oil stands up to high temps MUCH better than natural oil. Since I track my car regularly that is VERY important to me. I like royal purple, but I wanna try some different stuff. I run royal purple 20w50 generally because my motor is so old and has so many miles on it. Right now I am running some 10w30 castrol syntec that I got for free and I am not very impressed. The motor seems even louder and clunkier than it was with the royal purple. I may try some royal purple 5w20 racing oil that I also got for free for my next event this saturday. It should free up a bit of power.

mobil1 transmission fluid blows ass so hard it's not even funny, it would be no surprise that motul ran better, whilst also being a shitty tranny fluid.

Mobil one is the WORST tranny fluid you can put in our trannies. I tried it once. The trans ground like shit once it got hot. I changed the shitty mobil one crap out with some cheap ass regular gear oil the SECOND I got home.

Mobil one makes you and your trans ghey, it's the troof!
