    Toyota V160 fluid and Toyota T-IV are both ATF in nature. They are different fluids per Toyota as you can see with part number. The reason the V160 fluid column is gray is that it is the standard per the OEM guidelines therefore every other fluid is a challenger.

    Gotcha. Was hoping you can post the part # of the Toyota V160 so we know for sure which fluid to get (vs goin to the stealership and the guy telling me "oh ya this is the right one" and giving me the T-IV instead).

    See the picture above. The V160 oil will come in a box plus steel can.

    Thankyou guys very much and to Doug for the GREAT breakdown analysis. Top notch

    I am actually a BIG fan of both the V160 & T-IV for their respected transmission application. I have been using both w/o complaint.

    I commend you guys for spending the time and effort, but I think this is picking fly shit out of pepper. The spec for the oil is Dexron II based on the ESSO D21065 spec provided in the New Car Features manual. John Cribb and I chased this to ground years ago thinking we'd get a barrel of the ESSO stuff and provide it to the Supra community for a lot less than what Toyota charges. John has contacts in the petroleum industry. He works for an oil company. Dexron II is nothing special, and Dexron III is considered (by all the industry people) to be a perfectly acceptable replacement for Dexron II.

    The issue with Red Line's D-4 was pretty simple. Red Line told me (many years ago) that D-4 was the preferred ATF for our application. The problem with D-4 is, it has a very light viscosity and they pushed the seal swell (yes, every ATF has seal swell in it to different amounts) to the maximum allowable for ATF to ensure their super thin oil does not leak out of old seals. I have to say, it did most assuredly stop the shift shaft leakage I'd had from the very beginning which Toyota never did fix. Anybody else's Dexron III (Red Line D-4 is NOT Dexron III) works fine for the application. Really.

    Again I commend you guys for your work, but at the end of the day, the petroleum engineers don't look at the additive packages for ATF the same way Blackstone does. Blackstone is doing mass spectrometry to determine what elements are in the oil. Tribololgists (petroleum engineers) are looking at the ratios of the additives, their carrier oils, and the base stock used to make the product. Dexron of all flavors has ranges of acceptable for the additives. If all of these oils meet (or exceed) Dexron III specs, then they're all considered acceptable replacements for Dexron II. I am certain the Toyota T-IV is not considered Dexron II or Dexron III compatible or it would have been possible to run Dexron II or Dexron III in the Supra's automatics. Using anything other than Toyota T-IV was well documented to be disastrous, so I am not nearly as convinced T-IV is an acceptable substitute for any Dex, and ESSO D21065 is undoubtedly Dexron II.

    Having been all through the gearbox myself, having replaced all the synchros (got them sitting in a box if anyone wants to see them, I can post pics) and the synchro hubs (BTW, I only did this to update them to the more common second generation pieces), all the bearings and all the seals, I can very specifically vouch for NO WEAR ISSUES related to lubrication despite running Red Line D-4 in my Getrag for a couple of years. The only reason I replaced all these parts (at a total cost of $2.2k) was because I had no idea what I was going to encounter, so I figured I'd replace anything and everything on principle. I did crack a synchro outer ring, but it was purely my fault by overly forcefully asking that little synchro to stop first gear while moving at 20 mph. This is first gear, on a scale with the weight in grams:



    This is why I never shift into first at any speed over a dead stop anymore. That and the nastly little rolled sheet metal "pins" used to hold the shifter forks on the shift shafts...but I digress. You can see the shift forks here:



    Again, thanks guys, I've spent a lot of money with Blackstone over the years (I ran the WS ATF from my IS-F through their lab to see how it was doing not too long ago) and I know a big comparo like this takes both time and money. At the end of the day, it's not nearly as exact a science as we'd like to believe it is.

    If you really want to learn about ATF and why it isn''t all black magic (and why a lot of what you've tested isn't exactly what you might think) take a look at http://www.aftonchemical.com/Solutio...nsmission.aspx

    ^ I agree there is more science to this than what I discovered. I by no means is a chemicial engineer, but am a Mech/Ind engineer by degree and profession.

    This information was just to bridge gaps that have been apparent over the last number of years.

    Thx for all testing. BUT I will never be changing my RP. 15 years and NEVER an issue, Trans shifts better, quieter, no problems. I don't need a test to tell me what has worked. So not sure what the testing was trying to accomplish aside from maybe ruling out some fluids that are way off. Sorry but the Toyota v160 fluid shifts like crap at high rpm in comparison and price is ridiculous too.

    Tony,

    Last time I checked your not the staple of the MKIV or what works and doesn't.... The purpose of this testing was clear which you failed to understand.

    ??? I never said I was...Trust me Neither are you. I appreciate the effort and the testing and results. But real world experience and mileage and abuse speaks for itself as it has for many others as to which has worked best in their situation (RP). I was just simply applying the comment of "not sure what the testing was trying to accomplish" for those who are already jumping ship and ordering V160 fluid in a panic because they are afraid to destroy their transmission.....I don't see where its needed if using RP. Its not like these transmissions are under warranty unless you have the year warranty of a brand new one. In that case run v160.

    When I need a good read, I can sit on the shitter, look up at walls at my degrees, and read through all this....I see the point and totally understand...BUT 100K miles , shifting at 9500 banging gears for over 15 years using RP absolutely is a standard and a test environment I can go by. Might want to get out and try it sometime. Anyhow...as i said thx for testing.

    Where did I say I was? You obvious have a complex when someone comments on your arrogance.

    Been there, done than...I am at 92k and not too far off your 1/4 mile record with far less HP running OEM fluid...

    This may seem like a silly question, but what colour is the Toyota V160?

    My tranny is leaking red fluid and I'm trying to figure out which fluid the previous owner used. I'm also pretty certain the leak is not from the shifter seal.

    So the oils that were tested are "virgin" oils correct? Is there going to be a part two coming soon with samples that were used in real world conditions? Data is data but it would be nice to see how the oils break down over time.

    Thanks to all that contributed. I agree with Silver Bullet -- in the real world, RP has performed better for me in both of my 6sp Supras vs OEM V160 fluid.

    1993 Supra TT 6sp Hardtop -- 1115WHP -- 190MPH 1/2 mile
    2009 Corvette ZR1 -- 640WHP -- 10.12 @ 138.3MPH
    2007 Corvette coupe -- 500WHP -- Procharger P1SC
    2013 Infiniti G37x
    2010 Escalade ESV

    Formerly:
    1994 Supra TT 6sp BPU -- 11.8 @ 118MPH
    1997 Supra TT Auto BPU -- 12.0 @ 122MPH
    1994 Supra 6sp -- 72mm, VPC/AFC, stock longblock -- 722WHP & 10.36 @ 139.5MPH
    1993.5 Supra TT Auto BPU

    again thanks for all of those who contributed. I am so greatful to be part of a comunity that people still are putting time efford and money for r&d ect into a car that hasnt been produced in the us for 16 years. In all honestly some of these lambos and such are amazing but there isnt a car i would take over an mkiv supra.

    Op i have a question what would you call high amounts of torque? ive been back and forth some time now over what fluid to run in my trans and now its time to make a decioion so i can put this thing in the car. orignally i was just gonna suck it up and go the v160 fluid but ultimately it may be available now but no gaurentees it will be next time im ready for a fluid change so i just asume change it up now and im not sure what will be my best alternative. im unsure of the milage on my trans as i recieved it out of a car but did have 2 past owners say that it worked great with no noises and or grinds. i know before i got it it did have rp inside. i wont be doing any road racing but the car will see some strip and dig racing aswell as roll racing. ill be around the 750ft lbs of torque this go round and will be shifting at a higher rpm over stock. is that would you would consiter a high torque level? i need to see what is going to be the best alternative fluid for me the castrol toyota t-iv or the rp.

    I believe all automatic transmission fluids are dyed red to help differentiate them from other fluids, for leak detection and minimize the risk of filling with the wrong fluid.

AS an aside: They just made ATE recall 100% of their DOT Super Blue brake fluid because brake fluid must be clear to amber to be DOT approved. http://hooniverse.com/2013/08/16/bra...-distribution/
    Several years ago, I made the somewhat audacious statement that the V160 fluid was nothing special. https://www.supraforums.com/forum/sho...160&highlight= I said then, that V160 is most likely just standard Dexron II. I still stand by that. Just because it comes in a nice shiny can, inside a box and it cost $35/liter doesn't mean its special. It just allows Toyota to make more profit off the fluid. This is no different than the 'o'ring that Toyota sells for $3 in an individual bag which you can get bulk for $0.05. Even Kalrez 'o'rings (Perfluoroelastomer) do not cost anywhere near what Toyota charges for a regular old viton or nitrile 'o'ring. On the V160 oil not being special, don't just take my word for it, think about the math and the economics. What petroleum products company is going to develop a specially formulated oil for a production run of less than 200-300 barrels which would more than meet the needs over the full lifetime of the vehicle? The V160 is not that much different from any other manual tranny, an assembly of gears, syncros, rod, shift forks and some seals. The 'o' rings and other seals are either standard nitrile or Viton (unlikely but possibly Polyacrylate) which will react to petroleum fluids in a predictable way. I have been on this forum a long time and I have only heard of one documented case where the transmission fluid caused a failure. That was the shift return bushing swell problem associated with Redline D-4 which contained a high level of seal swell additive. It has since created lots of paranoia but little based upon scientific evidence. I still wish to pass my appreciation onto the group for doing the test. It's still an interesting topic. BTW: The latest recommended fluid for Getrag and BMW transmissions (1997 on) is Pentosin MTF 2. If you check the spec sheet it is almost identical in every category to Royal Purple SyncroMax. hmmmmm Pentosin produces OEM fluids (manual transmission, power steering, brake, etc.) for Porsche, Audi, BMW..... including the very expensive Porsche PDK double clutch auto/manual.

    Great thread and thanks to all who contributed to this test. I can't help but wonder how Toyota's new pricey fluid, World Standard, would compare to all these?

    “Toyota Gear Oil V160” by Castrol and “Nissan Mission Oil BNR34 Special” are specially formulated V160 Gear OILS… they’re not Dexron II or Dexron III... and IF it was, it’s not anymore. The color red doesn’t prove V160 gear oil is Dexron II or III... Marvel Mystery Oil is also red and the fact that they are “oils” proves they are NOT Dexron II or III. If anything is or contains DexronII... it will have the word “DexronII” somewhere on the label.

    The color of automotive fluids in the USA is tightly controlled by the DOT. AS an aside: They just made ATE recall 100% of their DOT Super Blue brake fluid because brake fluid must be clear to amber to be DOT approved. http://hooniverse.com/2013/08/16/bra...-distribution/
    If USA DOT is so tightly controlled... then why did it take them 15 years to finally ban it from our shelves? That’s another topic... we’re talking about gear oil. “Gear Oil” is not a “Fluid” it is an “OIL”. American Petroleum Institute (API) sets the classification for OILS, not the Department of Transportation (DOT)

    Several years ago, I made the somewhat audacious statement that the V160 fluid was nothing special. https://www.supraforums.com/forum/sho...160&highlight= I said then, that V160 is most likely just standard Dexron II. I still stand by that.
    Then you’re an idiot... again DexronII is an ATF... Automatic Transmission Fluid is not an oil, it is a hydraulic fluid. ATF is not formulated to perform as an “oil”, otherwise it would be labeled as an “oil”.

    Just because it comes in a nice shiny can, inside a box and it cost $35/liter doesn't mean its special. It just allows Toyota to make more profit off the fluid. This is no different than the 'o'ring that Toyota sells for $3 in an individual bag which you can get bulk for $0.05. Even Kalrez 'o'rings (Perfluoroelastomer) do not cost anywhere near what Toyota charges for a regular old viton or nitrile 'o'ring. On the V160 oil not being special, don't just take my word for it, think about the math and the economics.
    In Japan, ALL BRANDS and TYPES of OILS are only sold in metal cans (some w/boxes), there’s nothing special about it... it’s law and that’s just the way it is. Packaging this way is very expensive and not a profitable scheme to make more money... that’s what plastic bottles are for.

    What petroleum products company is going to develop a specially formulated oil for a production run of less than 200-300 barrels which would more than meet the needs over the full lifetime of the vehicle?
    How many years do you consider a “full lifetime” of a vehicle? 10years? 50 years? 100years?
    I’m assured in the begining, all the major petroleum companies had the opportunity to develop a special, low production V160 gear oil. To answer your question, obviously Toyota picked Castrol and Nissan chose Esso. So far, I haven’t had any problems purchasing V160 gear oil from Toyota... and when I do, I will purchase Royal Purple MaxGear 75W-90, which is specially formulated to meet or exceed the specifications of Toyota #08885-01306 V160 gear oil.

That was the shift return bushing swell problem associated with Redline D-4 which contained a high level of seal swell additive. It has since created lots of paranoia but little based upon scientific evidence.
    The V160/161 is a low production specially prepared Getrag 6spd manual synchromesh gear transmission found in the Toyota Supras (JZA80) and a limited number of Nissan GTRs (BNR34). (Not all GTR’s, just a special edition… I don’t know which edition.) If this Getrag V160 was no different than other manual transmissions, why didn’t Toyota and Nissan just make their own?

    The fact is, the V160/V161 6-spd transmission continues to be one of the best manual transmissions in the world to come equipped in any production vehicle... and apparently capable of withstanding failures when using the wrong oil/fluids.

    I still wish to pass my appreciation onto the group for doing the test. It's still an interesting topic.
    What test? There were no tests performed for oil degradation or ageing rate and there were no results!
    Dexron II/III, Toyota TIV, Mobil1 ATF, etc… are fluids, not oil. ATF cannot be tested as an “oil”… Blackstone Lab stated their process was,…NOT PERFORMED.

    “Total Base Numbers (TBN) analysis was not performed, as it is inaccurate for assessing ATF fluids as compared to engine oils.”

    BTW: The latest recommended fluid for Getrag and BMW transmissions (1997 on) is Pentosin MTF 2. If you check the spec sheet it is almost identical in every category to Royal Purple SyncroMax. hmmmmm Pentosin produces OEM fluids (manual transmission, power steering, brake, etc.) for Porsche, Audi, BMW..... including the very expensive Porsche PDK double clutch auto.
    Other than the Toyota and Nissan V160 gear oils, the latest recommended gear oil for the V160 is Royal Purple “MaxGear 75W-90”. Royal Purple does NOT recommend their “SynchroMax” for the V160, therefore the PentosinMTF2 won’t be on my list, IF what you are saying is correct. PentosinMTF2 is also a European Oil...

    “ACEA standards recognize that European engines differ from US (style) engines in both their design and operating conditions and that the demands on their oils are also different. This requires the oils used in European engines to be unique and consequently, the classification system for them also needs to be unique. For this reason it is difficult to compare the common API classification and ACEA standards, as the test sequences for them are quite different.”

    Very simple… If you are using ATF… remove it. Oil is Oil… ATF is ATF… It is, what it is.
