hydraulic oil????

Anonymous-0 · Aug 3, 2009

Hey folks,
trying to avoid taking out a loan to buy hydraulic oil to change mine.... Couple of years ago the neighbor dumped in motor oil (10w40). I've got a couple of seals leaking and thought I'd just change the oil while I'm at it. The local dealer wants about 8 bucks a liter for hydraulic oil,but I remember in the military vehicles I worked on with hydraulics, we just used 10wt motor oil. Is there a difference in the tractors, or will the 10w40 the neighbor dumped in not harm anything (hasn't so far unless it caused the leaks)?

Thanks, Dave

Morning Dave , or is that after noon almost for you?
On that same subject i remember running 30 weight oil mixed with gas to run our 2 stroke motorcycles back in the 70s. Worked okay.
I would say that old equipment could take whatever ya gave them. Better than watered down old worn hyd. oil???? Probably.
Why the heck is oil 8 bucks a quart. I thought 8 buck a gallon was bad.
What would it cost to ship 5 gallons to ya?

The term, (hydraulic oil), is very generic. Depending on the application, some of it IS 10 weight, some of it is closer to 20 weight, but hydraulic oil IS NOT motor oil, and YOUR tractor needs the hydraulic oil that the engineers desingned the system to use. You do not necessarily need to use the brand name that the tractor manufacturer recommends, but the brand you choose does need to meet or exceed the specifications for your tractor.

No telling what can be expensive here....... Shipping would eat up the savings. If it's just normal oil, I can buy it on post for a couple bucks a qt. Just found in the shop manual for the tractor to use SAE 20 hydraulic oil. Wonder if that's the same as SAE 20 motor oil?

hydraulic oil IS NOT motor oil, .[/quote]

Guess I'll just get off the bucks and put the right stuff in then. It's more than likely a one time deal anyway.

Thanks, Dave

In the Ferguson Group. We've been recommending 10W-40 for years for improved winter operation. This oil is of the same viscosity as the GL-1 90wt gear lube orgionally recommend.

So you will be fine.

What kind of equipment? 8 bucks a quart sounds awful steep.

a few months ago i was quoted by JD dealer that a 5 gal bucket of 303 hyd oil was $70. i called NAPA auto parts and the generic oil that meets all major specs was $35 for hyd oil. JD dealer said there is no difference in oil, just brand names and bucket color. difference is JD is shafting everyone.

use the manufacture recommended hydraulic oil to help keep repair cost low. I just had to replace the PTO clutch pack in a John Deere 2240 because of using cheap hydraulic oil. The repair cost $2,000.00 or the JD oil less than $200.00 for 10 gal.

Probably depends upon what you use it for. I think hydraulic oil is formulated to hold up under heat and high pressure better than motor oil. If you parked your tractor with a big bale hanging in the air from the loader, I'd suspect it might not hold as long as with hyd. oil.

You didn't say what you are using it on but for occasional loader or 3 point use, motor oil is ok, after all, it has worked for the last 2 years.

If it is running a backhoe or loader 8 hours a day, 5 days a week, then I'd use the recommended hydraulic oil.

I don't think the motor oil made the seals leak. Unless cold temps is a concern, you could go to straight 20 or 30 wt. or even a 15w40 used in a lot of diesels.

Here in East Texas both the NAPA and Bumper to Bumper part stores have genaric tractor/trans fluid in a 5 gal pale for $19.50. Even last year it didn't get above $25.00.

i went down that 'aftermarket' parts road. never again. oil is one thing, but foreign manufactured 'will fit' parts are something else.

VICKERS, the largest manufacturer of hydraulics
in the world, used to specify, in their catalog,
10-30, MS, SE, motor oil.
(I haven't seen a catalog since 2002, and know
that the MS-SE specs have changed)

Yeah, Deere sells their oil for about $50 per 5 gallon bucket around here. You're paying for the name.

buickanddeere · Aug 5, 2009

Drop by your friendly local Cat, CIH or Agco dealer. And price their trans/hydraulic oil. You may be heading back to the JD dealer for the lower cost material.

Hydraulic oil isn't all the same. Ask the guys who have replaced transmission gears or set clutch/brakes.
There is plain hydraulic oil for use in log splitters where there are no gears requiring lube or wet clutches.
There is trans/hydraulic oil with pressure additives to prevent gear wear in transmissions/diffs.
And there is trans/hydraulic oil with pressure additives and is wet clutch compatable.
What is going to happen to a tractor transmission with wet clutches/brakes when a low grade oil is added?
