The time came to think about replacing the transmission oil. There was no normal topics on our site and sorry. I had to smoke the Internet. On the Internet, there was a lot of controversial information not only which original pouring but the period of oil change (there is only 20 body). Some say that it is necessary to change through the 80t.k.p. Other than 60t.K.P. Third that after 40t.k.p. And in one place, the person recommended a change of oil through 160t.k.p. Someone with DRIVE2 wrote that, uses liquids for automatic toyota transmissions ATF WS, Toyota ATF T-IV, Toyota ATF-DIII. But elsewhere they argue that all these liquids are not compatible. Those. It is impossible to interfere. Only full replacement.
In our expensive time, the oil rose in price and besides, in our city there was no original now thinking about shift original oil on analog In addition, when replacing from the original oil to the analog you write that you must rinse the box. (i.e. full replacement with washing).
And so that I became known.


Toyota ATF WS conforms to the JWS 33232324 with the article 0888602305.
1) viscosity at 40c \u003d 23.67 - this transmission is really very economical, in conditions when the box is not yet free. Less viscosity oil is less resisting the box parts and saves fuel.
2) viscosity at 100c \u003d 5.36 - the same see the smaller viscosity when operating temperature - When the box is already a free.
3) Frozen temperature -44c is not a record of course, but quite normal for Russian winters.
4) Viscosity Dynamic Brookfield at -40С \u003d 9070 - excellent resultThis parameter is much more important than the frosted temperature.
5) corrosion on copper at 150c \u003d rating 2a - norm, 1B - is considered excellent, 2a is near ...
6) Sulfur content \u003d 0.060 - small sulfur content. That is, it is oxidized in principle there is nothing.
7) Standard additive package - a little phosphorus which is part of the anti-virus additive. Some calcium - which acts as a detergent neutralizing additive. A little boron is an anti-wear extreme pressure additive, or dispersant.
8) And most importantly, the oil contains estrices - which reduce wear and friction coefficient.
The oil is fully synthetic, has the best temperature har-kami and its service life is not 40 thousand km, but judging by the American manual, as much as 100 thousand miles, that our native kilometers is already 160 thousand km

The search for exist.ru issued a poor information. But Realparts.ru pleased with the analogues that you can buy the Yokki YCA041001P at a modest price.
In addition, in different forums, people declare that use the complete analogue of Toyota ATF WS.
IDEMITSU ATF TYPE TLS-LV, LUKOIL ATF SYNTH ASIA and LUKOIL ATF.

There is an open question.
What oils do you use? And what use the oil replacement period? There are ldi what experience you have.
From whom I heard that the prius 20 box is very capricious and does not like long replacement periods and quickly fails.
