Clear Hydraulic Dye

[BigG]

Can the red dye that they add to diesel fuel be added to the hydraulic fluid with out causing problems?

The site glass on my L2501 is just about useless because the oil appears to be clear.

Wiping a dip stick, from a TL80A, on a brown paper bag does not always work well.

I have read elsewhere that John Deere sells a dye specifically for hydraulic fluid.

MT3668 Oil dye

For those who used this stuff how much of it did you put in the hydraulic fluid reservoir?

 

[old and tired]

I put all of it in but you can definitely use less since mine is very dark. Try 1/4 and if that's not enough, add another 1/4...

1/2 bottle is plenty, it's pretty potent stuff. I've found the shelf life sucks so it may not be good for the next change. Here are some examples:

Receive my JD hydraulic fluid dye the other day. The bottle it came in was about 1/3 full and the instructions do say to empty the contents into the hydraulic reservoir. I'm guess there was about 2 oz?
Definitely works.
