In manual sad DOT-3, but I can`t find it (I`m in Russia, Saint-Petersburg), thats why I`m interested may I add DOT-4??

Anyway, Ranger -thanks

Dot 3 is original factory spec, dot4 has a higher boiling point and you should not have a problem using it, personally in my 93 seville (came with dot3) I flushed the system and am running 4...no ill effects

Make sure you flush the system of the old DOT 3 though...clear it out completely before refilling...they don't mix together well.
