My big cat machine was spec’d directly from Caterpillar corporation, to be fine with the same engine oil also used in the big hydraulic system. Had nothing to do with “counter jockeys “.

Interesting article but I'll stick with my synthetic hydraulic oil. I will say that Hydro-Gear specifies multi grade engine oil (15-40) for use in their hydrostatic drive units.

I don't have an emulsified water in the oil issue as my units stay inside when not in use and if they did get water in the hydraulic oil, I'm sure I get them hot enough during use to vaporize it anyway.

Whatever. I have a 'BIG Cat' as well in the barn, big 3406 NZ model to be exact.

You entirely missed the point of my post but that was expected.

Exactly what point did I entirely miss…that was to be expected?

My 50 year old CAT D3 dozer specified 20 weight motor oil.

I used to own a D3B

I used to own a D3B

It was a good machine and did everything I wanted but too heavy for me to transport when I ran out of work for it.

Now have a 350c I can transport and very capable but I miss the D3

Can it be used as hydraulic oil?

My CAT recommends 30 Wt Hydraulic oil, and as far as I can tell, it is just ordinary oil.

“While both oils are lubricants, engine oil and hydraulic oil are two entirely different products. Engine oil is a built-for-purpose lubricant utilized to clean and protect internal combustion engines, while hydraulic oils are non-flammable fluids employed in hydraulic systems.”

Here is a link direct from CAT that mentions substitutions only caution is not to use stationary hydraulic oil as is separates water from oil.

When I worked for Mr Choo Choo back in the last 70's all the
tie gang equipment that needed hydrolic fluid 10 W motor oil
was used. Many many years ago push lawn mowers needed the
30W non detergent
