I've had a look on here and people say any old one, but having a look on the Halfords website (not sure if this will work) Halfords There seems to be a massive selection and surely there must be something I'm looking for?

Thanks

 

Dexron II automatic transmission fluid (think there is a Dexron III but not sure of suitability)

 

Subaru's wk shop manual recomends Dexron III

 

I have an owners manual (classic) that says Dexron II or Dexron II E i wonder why the workshop manual says III.
Wonder why they say different numbers?
What is the actual difference?

 

Things change I suppose, Dexron II is quite an old spec oil & has now been superceeded by the later spec III.

Not even sure if you can still get hold of II ?
