I remember reading on HEF about adding a dye to Hydraulic oil to spot leaks and also be able to see the level better in the sight glass.
Who has a recommendation regarding where to obtain said dye besides Cat??
Thank You.

I buy it from Petro Can and it is blue in colour. What ever you do, wear gloves and do not drop 1 drop of it as it is super strong for staining something.

Yes. I helped in our southern Warehouse and a couple customers get dyed oils.
I got a few drops on the back of my glove and it soaked through. Took weeks to get the blue to wear off. The guy helping me was an idiot and grabbed the dye jug and cup with his bare hands. It made his hands all blue, which was impressive cause he was a colored guy

Did he then apply for the blue man group?

This is the dye I have used. It sure is expensive.
Walmart among other vendors sells it

Update,,, I purchased the John Deere Mt 3668 12 ml bottle for a little over $10 a bottle, I bought 02 since they are supposed to be used up to a 05 gallon system.
I put one bottle in and was pleased how much color it added to my 12 gallon system.
I guess I will hold on to the other bottle for a later date.
Your results may vary and Press On.
