Colors of lubricants, and grease for that matter, are just dye and have no effect on the lubricants properties. In this case the blue is likely a marketing ploy for colder temps and has a higher viscosity index. (The oils ability to stay in ISO Viscosity grade over a wide temperature range) The red for higher operating temps. As a Chevron lube engineer for 28 years and now working our Lube Tek lines we get calls about these Bobcat oils regularly.
CNH skid steers use to be filled with a blue hydraulic oil from the factory. CNH Technical Help Desk even has a knowledge article about it and they mention the marketability of the blue oil and that, just the fact that it is blue, it encourages repurchase of the blue oil.
Yep, even fuels are dyed. That's how the tax man can distinguish between off road diesel and road based diesel fuels.
Thanks for keeping us up to date on these changes!
You bet!
The original is an ISO 46 highly loaded with zinc, for anti wear protection, and polymethacrelate for improved viscosity index. It is a blended mineral oil API Group III and Group II oils. Found the SDS for it.
...but where's the spec sheet?
I'd love to compare it to Mag1's offerings.
$70 for 2.5 gallons of hydraulic oil is just ridiculous.
@jasono2139 I've had better luck with accurate data coming from the SDS, as well as usually information on who actually produced the stuff. The price is a bit high, but I've got trunnions that are getting an oil that's $37/gal. Trying to talk the guys that own it to swap to a graphite powder. Would likely save around 160k a year.
@OklahomaLubeDude still many hydraulic oil producers give a product data sheet with their oil's performance specs (Lucas, Valvoline, Mobil, Mag1, etc).
The only companies that don't offer this information are the ones who likely aren't producing their own oils (John Deere, Bobcat, etc.)
Similarly... I don't get what this guy is thinking saying "don't use AW 46... stick with ISO 46"... most companies are still making "AW ISO 46" hydraulic oil's.
AW 46 was already "ISO 46"... even if they weren't calling it that.
@jasono2139 I completely agree. It gets tricky though. I k ow a couple of years ago Citgo was making and packaging grease for other big name brands, and you would never know it.
The correct viscosity for the correct temperature is the single most important factor. Also an oil sample would tell you the viscosity if unknown.
Thanks for the update!!!! I probably should change my 2018 T770 over to the cold weather hydro fluid, at some point. During the winter up here in N. ID, I just start my machine about 20 minutes before I go start plowing snow. Warms up good, and haven't had an issue yet, other than my tracks freezing to the ground!!! Thanks again, look forward to hearing your updates!!! Till next video!!
Thank you for watching!
I see Bobcat now has the original stuff on hand, "back by popular demand", so I just ordered a 2.5 gal jug. 👍
Thank you for this info, just got a new T770 and was wondering what this blue oil was. And I’m in Texas so I guess I’ll be using the red
The rem seals were designed to run on engine deasel oil I never had truble deteriating rem seals with original bobcat seals.But this days quality of the seals is questioned.
2/19/24 t550 / 1900hrs contaminated hydr oil / water ‘milky’ from hold tank ( bad design ? As too easy to get rain etc into hold tank) how flush entire system to get clear oil again ? Thanks
I have a few of those black jugs on my service truck.
I’m located in Louisiana and my work puts super s premium universal tractor hydraulic fluid, multi purpose transmission/hydraulic and wet brake lubricant. Probably why all of our machines hydraulics are going out
Awesome, so neither of the new oils fit in the temperature range of most of Midwest.
Hey CNH just switched oil manufacturers a couple years ago.
I use to be a tech for a New Holland dealership in Canada and they have a rental fleet of skid steers and I was the main skid steer tech.
The 200 series New Holland and equivalent Case skid steers came with a blue hydraulic oil from the factory when that series was new. It was known as "hydraulic excavator fluid" and it was made by Viscosity oil company.
Later on in their production run they switched the factory fill hydraulic/chain tank oil to 10W-30 engine oil.
So the blue stuff was on a hydraulic viscosity chart as a cold weather oil and the engine oil was the hot weather oil. There was also a 0W-40 diesel engine oil on that chart for a synthetic oil option.
Later on again they switched their oil supplier from Viscosity oil company to Shell and that came with a complete rebrand of the oils that the dealer stocked.
The manuals now showed the cold weather oil option as an iso 46HV and the hot weather option as a 68HV.
My dealer however stuck with Viscosity oil company as their oil supplier and the hydraulic excavator fluid was now a 46 HV and there is a 68HV option now.
I now work at the local John Deere dealer and Bobcat is one of the short line products that we deal with.
I don't think that the "avoid engine oil at all costs" thing is really true if that makes any sense. Skid steer hydraulic systems are relatively simple.
The John Deere sprayers like the 612R for example use 26 gallons of John Deere Torq-Gard Supreme™ 10W30 in the hydraulic system. And that is a very expensive and complex hydraulic/hydrostatic system with flow divider/combiner valves for traction control on the hydrostatic drive system.
Just like MacDon uses 15w-40 oil for their header drives... whatever the system is designed to run on should have similar/equivalent oils.
For how frequently manufacturers are switching their hydraulic oils... you have to wonder if what you pick really matters all that much. 🙄
My Bobcat manual calls for ISO 46 with a minimum VI of 150 (or ISO 100 with 130 VI min)... but don't even list what ISO 68 could be used (probably because they wanted the ambiguous Bobcat "all weather" oil to appear superior in all conditions.
Almost nobody cares hydraulic oil with a VI over 120... if they are willing to list it at all.
Texas, we always ran motor oil, it gets so hot, common for new or use Hydraulic lines burst
Very informative! Thanks for posting!
I'm not that old, but I hate this kind of silly change. Here in Colorado I see 100 + to occasionally -25 ish. So what the hell do I use now?
We see the same temp variance in Eastern Utah
What about using Universal Tractor Fluid in place of these new Bobcat Hydraulic oils? Every time I go to my local oil supplier, he tells me that I can use Universal Tractor Fluid in place of the expensive Bobcat brand hydraulic fluid in my Bobcat skid steer machine.
I used 15w 40 engine diesel oil was recommended by local bobcat dealer haven't had much trouble now the machine S185 has 8500 hours all the ram seales start leaking now I change the seals and only lasting two months now I will change to bobcat hydraulic oil.
It seems you are talking about the newer machines and their hydraulic fluid. I am running older machines, 700 series skid steers and E32 and E35 mini ex. And I have been running AW32. Should I change to AW46? I'm in the south. Really love your videos, keep them coming. Thanks
Thanks for Sharing ! 👍
Things that make you go Mmmm LOL thanks
I've been running AW46 for years in my T200 and many hours....no issues
well on newer mustang skidloaders 1 joystick steering -30 below days it wont steer at all until you let it warm up 35+ minutes every single day and that expensive type1 diesel seems to disappear faster than type2. for my 853 i buy non soy diesel (so they say) year round from 1 station hoping the fuel system keeps working main thing with oil dont let it run low
If you have a lot of hydraulic attachments, or rent them, you're probably getting a lot of mixed oil viscosities. My question is, if you got hydraulic hoses that are beginning to seep around the metal connectors/crimps, should you go with a heavier oil ... will it stop the seepage?
I doubt it, time for new hoses.
Where I live we commonly get below 0 F and have summer temperatures above 100 F, so do we need to change the fluid twice a year.
As always, great content, thank you.
Much appreciated!
What's the story on this 1 year later , any problems mixing old type with new blue or orange ?
Can you mix bobcat oil with aw?
I have AW 46 in my Mini Ex. Would it be a good idea to drain the system and replace with ISO 46? Would it hurt to mix them?
What is "AW" 46??
ISO 46 is the viscosity grade... so it'd be the same as your "46" oil besides possible differences in the Viscosity Index.
Wish I had seen this sooner had a problem within the chain case had to drain the system and bobcat of course suggested their hydraulic oil😂 over 300 bucks worth.
Do you know what the word is on the new t86? With it being first year and all? Is it like a vehicle where it’s best to go with a second year allocation to allow for the bugs to be worked out by the manufacturers? Thanks really value your opinion
The wrecking company I used to work for used 10w-30 engine oil on the hydraulic system in the Bobcat machines. I was shocked when I first learned about it because I came from the Bobcat dealer. Come to find out, our operators were so rough on the machines, that the pumps would get burned up if we ran regular hydraulic oil. Apparently this company had been running 10w-30 for 20 plus years and they never had any issues
This makes sense since 10W-30 covers a wide range of temperatures.
10W is comparable to ISO 32 while SAE 30 is close to ISO 100
...so 10W-30 should perform well well anywhere ISO 32 to ISO 100 would be used, but it's typically more costly.
So i have a JD 260 skidsteer and my bucket tilts down all the way as soon a i turn the machine on. Any iead why ist doing this? Thanks in advance ☺️

Needed oil called dealer and the old oil was 65.00 for 2 gal but now the red is 85.00 2 gal found some one that had some old oil got 4 of them !!!
I’m in Florida and my new excavator just come with blue hydraulic fluid. And it’s hot as hell down here should I change it.
What about using Universal Tractor Fluid in place of these new Bobcat Hydraulic oils? Every time I go to my local oil supplier, he tells me that I should be using Universal Tractor Fluid in my Bobcat.
Valvoline has an article about the difference between their UTF and hydraulic fluid.
Most UTF seem to be closer to ISO 68.
I have a question for you. My T595 shows hydraulic pressure on the display that rarely goes over 385psi. I thought the hydraulic system would be operating at 3000psi or more. Is that supposed to be x10? I’m sure the operating manual that I have not read and lost explains it.
Only charge pressure is monitored as it should be static or constant, system pressure is infinitely variable up to system relief setting, which may be 3500 psi on hydraulic side and 5200 psi on hydrostatic side.
I am working on a Bobcat 873. I am working on the traction lock. When I removed the solenoid for the traction lock, I noticed the oil in the chain case is milky white. It wasn't like that a month ago. How would the water enter the system? any thought would be helpful. Thanks in advance.
is it an enclosed cab ¿ usually water get in from the rain between the operator leg plate
Thanks for the great videos.
Is chevron 1000 THF AGCO power fluid decent hydraulic/ hydrostatic oil for a T 300?
This not about oil, but you have a lot of bobcat knowledge and I wanted to ask advice. I sold my 753 and my jd450b and I'm looking for track skid steer. There is a t200 with 5200 hours close to where I live, what is your thoughts and what should I look at? Thanks for your help!
That's a lot of hours. They are known to start having issues after 4000-5000 hours.
@@rafaelcardenas1202 I didn't buy it after all.
can you mix regular hydraulic with the bobcat brand hydraulic ?
Yes it can be mixed
Amsoil
Engine oil *is* used in high-pressure system, eg. HEUI engines rely on engine oil and *will* operates up to 3000psi.
Thanks!
Thank you!
10w30 engine oil.
Can you mix the new and old oil?
Yes the oil can be mixed, maybe
As per the manuals, yes
I know this is a long shot but I'm in need of a ecu for a t630 part number is 7030329. If you have one please let me know i have changed with bobcat and out of stock and don't know when they will get it in.
