Car Jack Oil - Ok to replace SAE-10 with ISO-68?

[mtbvfr]

Hi Folks,

I have a Car Jack that is rated for 1500 kgs and the specified Oil is SAE-10.

It needs topping up.

Would it be ok to use an ISO-68 oil if I can't find ISO-32 nor SAE-10?

Thanks, MTB.

According to the SDS linked on this STP, it's 32CSt ar 40C, so if you need ISO32, this should be the right viscosity.

I've seen jack oil the cheapest at Walmart. It is on a shelf around the floor jacks I think, not where spray lubes and auto chems are.
I would never use 1/2 of the quart bottle from Auto Zone the rest of my life. I'd get the smaller bottle

Robot or human?

This only thing about that is if you look at the SDS, it's apparently only ISO12.

ISO 32

Are you indicating, then, that ISO-68 should NOT be used in an hydraulic jack when ISO-32 (SAE-10) is the specified viscosity.

What would be the outcome if someone attempted to use the ISO-68?

harder/slower to jack up and slower to drop... might not drop at all without weight on it if it's a bit cold
