Anyone DIY dye their hydro oil?

[WinterDeere]

Doesn't diesel oil start changing color pretty early on due to the soot over time or are they so clean now that doesn't occur as soon?
I know my 04 Dodge Cummins cranking 600hp 1200tq out the rear wheels doesn't need an dye LOL

Crank case oil, sure. But this is hydraulic oil.

Thanks for the question. It made me remember that I used to press some dip stick or other against a paper towel. The towel must have been the cheap brown kind because the length of the stain was easy to see.

That's exactly what I've been doing on this particular tractor, the last 6 years! PITA, but it works.

I have the same problem with the 5W30 synthetic oil in my generator. It runs so clean that even after 100 hours it’s nearly impossible to see on the dip stick. Might this be an option in the engine oil?

My eyesight is fine, this is an issue of trying to spot glossy clear low-viscosity fluid on a glossy metal stick covered in stamped X's. Like finding where a painter stopped one day and picked up the next, with the same color and sheen.

I’m not debating your eyesight. Microscopes and telescopes are used by many with perfect vision.
I posted 2.5x magnification “cheater” glasses. They simply magnify and enlarge what you’re looking at.
I’d bet with good lighting or a flashlight, and these $4 cheater glasses, you could definitely see your oil. Or buy a dye

I keep cheap cheater glasses all over the house. I think I have a pair in the tractor storage area too

Did you get that local or order it online? I have been wanting to add some to my tractors.

Online/Amazon Have used both the JD and Rekheo. Both work, does not take much. I think I used half a bottle on my L, about 10 gal

I made a sight glass for my 318/44 loader and use yelloe dye in it.

I had the JD red dye carry over after the last full hydraulic fluid and filter change on my Kubota MX6000 just from the residual fluid that doesn't drain out fully.

It's now pinkish...but still visible.

I was given a bottle of blue oil dye, Petro-Canada branded.
It takes a very small amount.
Not only does it make the hyd. oil easier to see on the dipstick, but it makes leaks easier to spot, especially in the snow, and theres no other blue fluid around to confuse it with.

A bit off topic maybe, but I remember as a kid, my dad used Royal Triton motor oil in the car, it came already tinted purple!
Must have been a marketing gimmick!

Those with a dip stick can take a clean shop rag or paper towel, which hopefully you have with you when checking, wipe the stick, dip it, then lay it down flat on, or squeeze it with, the paper towel or shop rag, and look at the stain. Bit of a pain.

Those with a sight glass might take a small flashlight and try shining it at various angles.


I'd try those things first before adding dye to an expensive hydro.

I’ve never had an issue with a sight glass if it was properly filled. If the level isn’t within glass it can be hard to know if it’s low or high. The tube glasses are better in that aspect but some sight glasses are only about the size of a quarter. My skid steer sight glass has a ball that floats in the tube that fixes that issue. I also carry a pocket flashlight that I probably use 50 times daily.

BTW, I bought the Deere dye I had linked above, and it was a little (1 fl.oz.?) jar that read "add entire contents to any system up to 5 gallons capacity." The dye is actually red, not green as others here had reported for their Deere dye purchases.

I didn't bother to look up the hydro oil capacity on my 3033r, memory tells me it's over 5 gallons, but whatever... I added the jar. Then because much of it was probably lying in the internal threads of the filler neck (didn't want to waste any in a funnel), I filled the jar with clean hydro oil, shook it around, and used that to get the last of the dye from the bottle and douche the threads in the filler neck so the cap (hopefully) wouldn't glue itself in place with dried dye over the coming months.

But after a day of short stints moving the tractor around (walnut harvesting), the fluid on the dipstick still looks clear!
