Aloha folks is power steering fluid hydroscopic as is brake fluid. I have a bottle of steering fluid that is about two years old. Is it still good if the cap is tight?
Tks Ed
 
@Ed Fenwick
Per OwnersManual, PowerSteering uses same MerconV Fluid that should be in your 5r55e Transmission;
nonsense to buy overpriced seperate bottle with unknown contents labeled "Power Steering Fluid".
Tight lids on bottles keeps moisture+dirt out, unless you're in an equatorial steam bath climate.
Every 6mths, got a routine of HandPumping ~1/2qt from PS reservoir then refill with fresh MerconV;
also HandPump ~1qt of old fluid from TrannyDipStickTube & refill with fresh MerconV,
along with the usual semi-annual EngineOil+Filter change.

Yea, I went to google (even though I don't like them) , so I went to Yahoo. One post read that power steering is just like brake fluid, it is not hydroscopic! That is why I went to you guys.
 
Literally let it run and heat up, shouldnt have any moisture buildup. I added a replaceable filter on my f250 to the return line, seems to help keep crud from recirculating.
