Must have
Must have in each technicians or enthusiast toolbox! Had oil seepage in hard to reach areas. Washed engine really well, confirmed with UV light nothing is glowing. Poured dye in and gave car quick drive around the block. Allowed engine bay to cool a bit and inspected with UV light: instantly found larger oil leak through dipstick tube and tiny seepage at timing cover. Saved hours on troubleshooting. Extra benefit, since dye can stay in the system, was able to confirm repairs worked. In my case dye still glows after driving for 200km

Find the leaks
I noticed oil under my Truck. Engine compartment area. And the diet founded located very quickly. It’s great to try and use because then you’ll know if it’s something major or is it just something that she can get to?.

This dye really works great and doesn’t cost a lot.
I have been fighting transmissions leaks in my 67 Camaro for ages. The dye really lets you see the source of the leak. I cleaned under the car really well and added the dye. Then I drove it a few miles. Using the special glasses and the black light I got with the dye, I could see exactly where the fluid was leaking from. The dye will not hurt anything.
