From my understanding ... The JD bottle is small and is not "full" they state 12 mil which I presume is "milliliters" I know it's a tiny amount, and half the jars are pasty ... A little does go a long ways but say it's for 5 gallons ... Lots of dealerships don't seem to even know about it, but if given the number they can order it, this is what I've gleaned over at Green Tractor Talk forum ... I didn't buy it, seemed expensive to me ...
On my Kubota L5030 it has a dipstick, and I don't need the dye to see it, so only use it in my MF, my JD has a translucent tank, and I can see in it there basically clear Hygard fluid in it ...
On my 1st use, I tried to drip it into the back of my tractor, (bottle is FULL!) I had my BH on, and it was challenging to say the least, I have red stains still on the back of my tractor, even though I tried to get it off, I'm guessing if I had tried something like brake cleaner, it may have gotten it clean, but I just used soapy water and a brush, I now have a red stained brush! It did read somewhere that it can be used in water, so I figured water would wash it off, I got "some" off my tractor and fingers with soapy water, some!
I did talk to my Massey Ferguson dealer about it, as they also don't sell a dye ... He said no problem using it
