Stealers are selling Dex V1, in place of Dex 11, power steering fluid for my tractor. Is this OK? :-/
TIA
-
Dexron VI supercedes previous versions and is fully backward compatible.

Thanks a bunch KW :y :y :y

There are some documents on the web that suggest that Dexron VI superceded Dexron III as of 2006 (?) for use as ATF.

I can't see anything that suggests that it is also now the recommended PSF, although I have heard it said that ATF can be used as PSF.

It's the same stuff.
Some manufacturers have their own dedicated oil for power steering so you have to ensure you use that fluid, but that is not a problem on the Omega.

It was interesting to hear my stealer parts man saying that they don't use GM ATF, but buy in drums of equivalent from Comma. So much for OEM!!!
-
That's because GM ATF (which is made by someone else obviously) is very expensive compared to Comma.
Often the bolt on 'masterfit' type outlets at the side of the dealers will use cheaper alternatives then genuine.

This was a VX dealer!!! :(

Just to be clear,
dexron 11 is for pas
dexron 111 is for atf
do NOT mix thier applications,
the above are approved and issue free, the fluids that supereceed these are not proven in the omega so far.

There is no problem in mixing if you are putting in an oil that exceeds the minimum spec (eg, putting Dexron III in the PAS that only needs Dexron II), it will however be a problem if you (say) put Dexron II in your gearbox when it needs a minimum of Dexron III.
Dexron VI meets & exceeds the specs of anything before it, and was designed from the off to be fully backward compatible with lesser spec oil.

FFS, pas was changes from 3 to 2 due to problems with power steering pipes leaking acvording to info on here i believe. The recomended fluid is issue free why introduce other variables?

Was it proven that the use of Dex III was the sole cause?
If so, I'd imagine that opens the floodgates for a lawsuit as GM dropped all licensing for anything other than Dex VI, and now only offer said Dex VI as the alternative.

Don't be silly, he is all knowing, and will never be wrong, in anything ;D

mentioned in this link but does not mention the reasons why, cant remember where i gut the leaking pas pipes from but i'm 90% cretain thats why, doesnt really matter and i cant be arsed to find the relevant page. All you need to know is in the link.
I'm sure the op will make up his own mind.

Automatic Transmission Fluid (ATF)
Vauxhall say: Automatic transmission oil change is required every 60,000 miles or six years, but only under ‘extreme’ operating conditions i.e. when towing of when using the car as a taxi.
We say: change fluid anyway at 40,000 to 60,000 miles / six years, regardless of operating conditions.
Also, a change of transmission fluid (and either cleaning or replacing the filter) is the first port of call when dealing with ANY sort of automatic transmission problems – you will be surprised how many boxes were revived by this simple measure after having been written-off by main dealers…
Vauxhall own ATF is quite expensive, you can use any good-brand full-synthetic ATF but it MUST be to Dexron III spec.
Power assisted Steering (PAS) Fluid
There is no scheduled interval for PAS fluid change, but if it needs topping up then the correct fluid is ATF Dexron II. For some reason Vauxhall say that Dexron III should NOT be used for PAS, only Dexron II.
From TIS : Field Remedy 1570
TIS 2000 indicates that the power steering oil specification for Vivaro is
Dexron III. This is now incorrect.
The original fluid was Dexron III (PN 90 510 269, Cat-No. 19 40 763) which
was used to service certain power steering and automatic transmission fluids
(ATF).
This oil is no longer available so a new version of oil Dexron III has been
specified for the affected ATF (PN 93 160 372, Cat-No. 19 40 712) however
this oil is not compatible with power steering systems and should not be
used for this function because this may result in leakages.
To service the power steering system the oil now specified has reverted back
to Dexron II (PN 90 350 342, Cat-No. 19 40 700).
This should prevent any confusion when trying to select the correct oil for
the correct application.
NOTE: This information is valid for all models except Sintra (partnumber
90 513 486, Cat: 19 40 707) and Astra-G/Zafira/Vectra-C/Signum (partnumber
93 160 458, Cat: 19 40 715).

Fixed link, thanks Entwood.

Thanks a lot guys. However, I have now topped up with Dex V1. I'll let you know :-?
-
one of these days KW you'll allow someone to tell you something...
I don't have a problem with being told something Chris.
What I have a problem with however is when somebody says something, admits they "heard" it somewhere, and can't follow it up with definitive proof.

so next time i'll sit still keep quiet and allow you to tell someone to damage their car? i'm quite sure the only definative proof lies in a safe at gm hq or some other cloud of intrege, however this is a very well covered subject that i've quoted on several times and frankly cant be arsed as i know it to be correct.
To be fair to you though your logic is sound it seems to me, and i do wonder what we'll use if dexron 2 or 3 really does become hard to find.

If you read the GM info carefully it seems that they introduced a new Dex III that was found to be incompatible with PAS systems:
This oil is no longer available so a new version of oil Dexron III has been
specified for the affected ATF (PN 93 160 372, Cat-No. 19 40 712) however
this oil is not compatible with power steering systems and should not be
used for this function because this may result in leakages.
I also recall reading (probably somewhere in TIS - more hope of finding a virgin in a brothel than locating it again!) that it was due to incompatibility with hoses or seals.
Whether that would apply to all Dex III products on the market of just that one specific GM product who can tell? In principle the specs are "backward compatible" but given that PAS fluid really doesn't get worked hard anyway, I'd use Dex II if available and avoid risking it. There's no advantage to using a higher spec fuid (apart from having some left over following a gearbox fluid change).
