ATTENTION!
DO NOT MIX ATF TYPE T AND TYPE T-IV (JWS 3309).
(when switching to ATF T-IV, do only a complete oil change in the automatic transmission)
Toyota recommends using Toyota ATF Type T-IV automatic transmission oil where the use of earlier types of oil - Toyota Type T-II and T-III is recommended.
It can be seen from the table that it is permissible to use the next generation of ATF, that is, everything that is higher in class. Reverse substitution in the direction of lowering the class is unacceptable. Dexron III replaces Dexron II / Type T-IV replaces T-II
The latest generation of gear oils - TOYOTA ATF WS (JWS 3324)
Fully synthetic low viscosity fluid, mandatory for use in vehicles for which it is indicated in the Owner's Manual, should not be used in the absence of such a recommendation. Not interchangeable with other types of fluids TOYOTA ATF Type T-IV, Dexron. Since this type of oil absorbs moisture, it can damage the transmission. Therefore, it is recommended to use an open container only once.
General principles for changing oil in automatic transmissions.
Do not mix oils of different grades. All settings of modern automatic transmissions (after 2003) take into account the specifics of the work of OEM oils. And these are not only those characteristics that are described in the specifications, but also how these characteristics change during heating and "aging". After all, with oil contamination, the lubricating, heat-removing and frictional properties of the oil change. If you are not sure about the type of old ATF oil filled in the automatic transmission, do a complete oil change.
Universal gear oil AISIN AFW+
Universal automatic transmission fluid (ATF) from the Japanese company AISIN SEIKI CO., LTD, which is part of the TOYOTA concern. AISIN is the largest developer and manufacturer of automatic transmissions and CVTs Based on its experience and the most advanced technologies, AISIN has developed a series of specialized ATF and CVTF fluids for the service market.
The manufacturer recommends changing Aisin oil in automatic transmissions at least once every 20,000 km or once every 2 years, whichever comes first. In this case, priority is given to a complete oil change in the automatic transmission using a special installation.

Each automobile concern is trying to ensure that technical fluids do not harm the units. In the event of a breakdown, it will be difficult to prove to consumers that the manufacturer is not at fault.
In this case, the reputation of the brand will be irreparably damaged. For this, there are specifications and approvals, as well as oils produced under the name of auto concerns: such as Toyota ATF WS.
Automobile manufacturers do not have to open oil refineries. You can simply order the required product from recognized masters.
Toyota has signed a contract with the American oil producer Exxon Mobil Corporation. The plant that produces lubricants for Toyota is located in Japan.
Destination Toyota Genuine ATF WS
The transmission fluid was developed jointly by Japanese and American engineers for Toyota, Lexus, as well as other models produced on these platforms.
The composition of the oil works perfectly in Japanese-made automatic transmissions: Aisin. There are restrictions on the year of manufacture: Toyota factory approval only applies to models manufactured after 2004.
In addition to automatic transmissions, Toyota ATF WS oil is used in CVTs. This type of transmission is found in most Toyota hybrid vehicles, such as the Prius.
This fluid is successfully used in Toyota sequential gearboxes, although this is not the main purpose. It's just that the operating conditions of automatic transmission units are similar to the loads in sequential mechanisms.
Since the abbreviation WS stands for World Standard, this transmission fluid can be poured into automatic transmissions and CVTs on all Toyotas and Lexuses, regardless of the production market.
Japanese, European, North American and African versions are equally compatible with ATF WS. In addition, the transmission can be used in other brands of cars if the oil characteristics match.
Positive properties of Toyota ATF WS
The main virtue of this oil is its long service life. Potentially, many users perceive the transmission as irreplaceable.
If you purchased a used car, or are going to operate the car for longer than 100-150 thousand km, the fluid in the automatic transmission or variator must be changed.
Important! Even if your engine does not have a traditional dipstick in the gearbox, there is still a way to replace it.
- the oil can work for a long time under conditions of high load on the gearbox: frequent and abrupt shifts practically do not change the characteristics of the fluid;
- switching is smooth, without a negative impact on the mechanisms, regardless of the type of gearbox (automatic transmission, variator, sequential);
- a set of special additives that reduce friction and wear of the metal parts of the shift mechanism;
- universal temperature regime: practically has no restrictions on the climatic zones of the Russian Federation;
- manufacturers managed to combine various qualities that are usually antipodes: low viscosity and high adhesion;
- balanced content of esters reduce friction loads and reduce wear of gear teeth;
- creation of an effective package of additives based on phosphorus and boron allows saving on production costs;
- calcium is present in the lubricant: the transmission fluid has good detergent properties;
- low ability to internal oxidation and protection against corrosion of parts of the gearbox.
The form of release can also be attributed to the positive qualities. The most popular packaging is a 4L tin can. Article Toyota ATF WS 08886-02305. 
By purchasing such oil, the buyer can be almost 100% sure of its authenticity.
Basic characteristics and tolerances
- the base is pure synthetics;
- viscosity index = 171;
- kinematic viscosity measured at 40°C = 23.7;
- kinematic viscosity measured at 100°C = 5.4;
- loss of viscosity characteristics at low temperature (pour) = -44°C;
- dynamic viscosity according to Brookfield at the beginning of operation (test temperature: - 40 ° C) = 9070;
- impact on non-ferrous metals is below average;
- sulfur content of the composition is less than 0.06%;
- content in additives (mass fraction): phosphorus = 271;
- content in additives (mass fraction): boron = 62;
- content in additives (mass fraction): calcium = 114.
The tolerance is practically the same, it comes from the name: Toyota ATF WS. All other specifications from Toyota do not fit.
Toyota ATF WS gear oil analogues
Of course, almost all manufacturers of technical fluids produce similar compositions, we list the main ones:
- Aisin ATF AFW+
- ZIC ATF MULTI
- Castrol ATF Multivehicle
- Liqui Moly Top Tec ATF 1200
- Petro-Canada DuraDrive MV Synthetic ATF
- Idemitsu ATF Type-TLS
However, Toyota ATF type T IV transmission fluid is closest in performance. In fact, this is the predecessor of ATF WS, which was produced for filling in gearboxes and CVTs of previous generations of Toyota and Lexus (until 2004). 
Despite the similarity of the parameters, Toyota ATF T IV does not have ATF WS approvals, but continues to be produced to this day. Given the survivability of Toyota and Lexus cars, this transmission will be in demand for a long time to come.
Toyota WS is used as a CVT oil in many Toyota and Lexus hybrids such as the Prius.
Toyota ATF WS transmission oil has a long service life, sometimes it is interpreted as a lifetime. However, like any oil product, the liquid oxidizes, which leads to an increase in its viscosity, and as a result, to an increase in fuel consumption. The oxidized liquid is not able to withstand high-temperature deposits. Toyota ATF WS can be replaced even when there is no pin on the box, which is usually interpreted as "non-maintenance" of the automatic transmission.
The name Toyota WS stands for World Standard, i.е. world standard automatic transmission fluid. The global trend in automatic transmissions is to reduce the viscosity of the working fluid, which reduces internal friction losses and leads to a reduction in fuel consumption by the car. In this regard, the viscosity of Toyota ATF WS is lower than that of fluids from previous classes from Toyota and is about 6 cSt in working condition (1 cSt is the viscosity of water).
Toyota ATF WS automatic transmission oil meets Toyota ATF WS specification
This fluid is manufactured by Exxon Mobil in Japan.
Foreign cars of Japanese production drive on the roads of the country. Toyota fell in love with the inhabitants of Russia, and also Toyota ATF transmission lubricant consistency.
Lubricating fluid is bought for pouring into automatic transmission crankcases. It has become a rule for lubricant manufacturers to color the fluid green or red. The coloring is done deliberately so that drivers can distinguish the product from motor counterparts and other lubricants.
The use of ATF in Japanese cars is subject to some requirements from car factories.
- In particular, this kind of oily liquid is necessary for the valve system;
- It is optimal in viscosity during the operation of the brakes and the conversion of the torque of the gears;
- Pour fluid into the steering system, articulated with a hydraulic booster.
Useful Chemical Additives
The oil purchased by import in the molecular structure contains material inclusions, which make it possible to provide important operational parameters. Such iconic characteristics of Toyota ATF WS brand include additives that provide:
- long-term operation of rubbing parts and assemblies;
- barrier to the appearance of chemical corrosion reactions;
- increase in viscosity indexes;
- increasing the speed of vehicles;
- thickening of the lubricating consistency in the hot season.
The produced oil is characterized by the fact that it is produced personally for each model of the Japanese car manufacturer. The specifications attached to the product give customers a complete information picture about the use of the lubricant.
Replacement frequency
During the operation of the car, the lubricant loses its original properties. The oil is saturated with microscopic metal dust. The wrong lubricating fluid poured into the crankcases leads to damage to the gearbox components, the transmission as a whole. For the normal operation of foreign-made cars, it is necessary to regularly replace the lubricant. For filling, lubricants are used, which are indicated in the specialization specifically for this type of car. Replacement is made after the car has run 80,000 kilometers.
Allows partial replacement after a vehicle run of 50,000 kilometers. A complete replacement is permissible with a run of 100,000 kilometers. In the latter case, motorists dispose of the old filter by installing the original new one.
Analogues of the Japanese ATF WS
In operational driving practice, many use other lubricants instead of toyota atf ws. On the forums you can read a lot of positive reviews praising analogues.
- In particular, the multi ATF lubricant received flattering characteristics. The term multi means that the oil is suitable for use in vehicles equipped with automatic transmissions.
Laboratory studies have shown the promise of use. Lubricant analogues have shown the same qualities as the original lubricant. The lubrication eliminated the loss of energy used to transfer torque from one gear to another. This is noticeable when the car is moving, especially on rough terrain.
There was an increase in the efficiency of flowing energy transmitted from the power plant to the transmission units. The used multi substitutes demonstrated excellent vehicle dynamics when driving. Considerable fuel economy has been noted.
At cold start of engines, analogues behaved just as nobly as original lubricating fluids. An analysis of the protective properties of the replacement lubricants showed that the wear resistance remained in the coordinates of the required parameters.
Conclusion
The proposed Toyota lubricants of the ATF WS marking, imported to the liquid trading floors of the Russian Federation, are fully adapted to Japanese cars. The product is also certified by domestic attestation state institutions.
The price of a product is set by the market. The cost of transmission fluid is only vulnerable to fluctuations in inflation. Unfortunately, inflation in the country is in progressive development.
