Hey folks, need to top up my steering fluid. No Mobil ATF320 PAS fluid any where. Can I use Dexron III? It seems Mobile ATF320 is exactly that.

Edit: Replied to wrong thread...sorry!

 

Worth investigating why you need to top it up. Mine was low and I got a slight vibration in steering in icy cold weather. Turned out the power steering pump was leaking - replaced on warranty. Apparently not an unusual problem (same with the coolant pump apparently).

Owner's manual suggests a Dexron III can be used if the Mobil isn't available
