TRACERSpectronics Corp TP34000008 Dye-Lite All-in-One Full Spectrum Oil Dye

the dye itself is great! in fact after an oil change I can still see it.the bottle, no... it leaked all over the inside of the box and all over me, the garage floor, et cetera. it looks like I robbed a bank and a dye pack (if they exist) went off. I've scrubbed my hands for a week and I still can barely see a different glow to my hands, my garage on the other hand is still glowing nicely.

Found Power Steering leak with this. Put in maybe 3/4 of the measuring section, so not too much. Ran car for 120-360 seconds. IMPORTANT have the hood up, and in a dark place with a UV light shining near your leak. Once you start to see it, in my case I saw UV "dust' floating in the air. TURN THE CAR OFF!!! I still had to search for a little to find the actual leak point, but if I kept running the car it would have spread the dye everywhere, making it useless.

easy to see with the UV LED flashlight I got elsewhere on Amazon. Be careful how you store it, the bottle ended up on it side in my garage and it leaked a bit. I have it where it won't do that again and have it in a quart ziplock bag.

The dye ended up leaking some, and onto the inner packing, probably a third of the dye. It's probably a good product, but the squeeze to measure system, while very convenient and ingenious, created a path for leakage...

Using this to dye clear hydraulic fluid that I bought "sight unseen"---and now can't see it in the sight glass on the tractor. It works.

Good uv glow mostly used for oil leaks

Works

Works like a charm! I was able to find all the leaks.I asked at local auto stores if a solution like this exists and the answer was that is no solution to detect the oil leaks.I would by this again.
