Touch control fluid

Postby Big Mike » Mon Jan 29, 2018 9:07 am

I saw in the old online manual that the touch control system used SAE 10W motor oil. Is that what everyone still uses or is there a hydraulic fluid that is best for the system?

Hy-tran or compatible is preferred now.

The early manuals said 10W. Later the manuals switched to specifying Hy-Tran.

Steiner recommends 30W so if the pump seal fails it won'd dilute the engine oil. I can see where that might not perform well in very low temperatures.

Probably going to get flamed for this - mine currently has 10W30 in it.

That's the dumbest thing I've read today (not geared toward you). If you get oil in your oil it's still oil and you'll know you have a problem when the lift quits working from lack of oil. Does Steiner also recommend running oil in your cooling system in case you blow a head gasket you won't get water in your oil? :lol: :lol: :lol:

Both bad choices. Stick with Hy-Tran or equivalent. Reasons have been explained in past threads.

the 10 weight oil was supposed to be non-detergent. The older 0-rings, etc. did not like the detergent oil. HyTran or equivalent is what was called for in a few years and is a much better fluid for the touch control systems.
If you are not part of the solution,
you are part of the problem!!!
