What to add to hydraulic reservoir behind Radiator
Need to top off the hydraulic reservoir that is below the surge tank behind the radiator on my Freightliner.
Label says "Dexron III or equivalent" which I understand was standard in 2002.
Now it is 2010. Web research tells me Dexron III is no longer supported and has been replaced by Dexron VI, but still see Dexron III for sale.
Does it make any difference?
Any comments are appreciated.
