OK, I have read all the threads about changing the power steering, engine fan and brake assist oil in the engine compartment hydraulic system reservoir to Rykon or Hondo HDZ as it is now known. I have looked at the cost of the new fluid, the oil replacement procedure and read the comments about the minor improvement that resulted and have decided to change the filters, drain the reservoir and refill - but with WHAT ? ? ?
My 2006 owner's manual says Valvoline power steering fluid, but somewhere along the way since I bought the coach in October 2005 I have crossed out the Valvoline power steering fluid and written in 15W40 oil.
The 4-5 gallons I drained out of the reservoir does not look or smell like power steering fliud but them I'm not entirely sure it's 15W40 oil either! !
It is a translucent, slightly brown oil that certainly LOOKS, FEELS and SMELLS more like motor oil than PS fluid.
And to make matters worse someone told me they may have used ATF. I have lots of ATF but it is a reddish color.
Now that I am suitably worried about the compatibility issue I'm not sure what to add.
