## Questions & Answers

**Q: Will i need to change the oil after adding the product or can i run it 3k miles?**
A: You probably don't need to but....I personally would add the UV dye right before you need a oil change. That way you can drive your vehicle for however long. Probably a good 2 days, drain the oil/ fix the problem, then refill with fresh oil.

**Q: do you really need the yellow goggle to see the dye?**
A: I had no problems seeing the dye without the glasses.

**Q: can this dye be mixed with mineral oil and used in smoke test machines**
A: The answer is yes.  I used it in my smoke machine to test an engine in my 1996 BMW Z3 1.9.  It worked fine.

**Q: So i just pour all of this bottle into engine oil and look with blacklight?**
A: Thats exactly what I did to locate a hard to find oil leak. BTW: to get a clean read, you will need to clean the engine beforehand, add the dye and then drive 20 miles or so to locate the leak.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Added to my lava lamp to make the lava (wax) black light responsive.
*by  on Reviewed in the United States 26 July 2026*

Added to my lava lamps to make the lava (wax) UV/black light responsive. Works great. A little goes a long way. A drop or two is all you need. Using more will change the color of your wax. Highly recommend. Fluid is dark red but glows green on any color wax. Don’t expect it to make orange wax glow orange, etc. It does not change the color or leach into the fluid.

### ⭐ Useless
*by  on Reviewed in the United Arab Emirates 24 August 2024*

Does not identify leak

### ⭐⭐⭐⭐⭐ An absolute time saver.
*by  on Reviewed in Australia 24 April 2026*

If you are chasing a "phantom" leak that seems to be dripping from the sump but you suspect is originating elsewhere, this UV dye is an absolute lifesaver.I used it to track down a stubborn leak on my Alfa. From underneath the car, everything pointed toward a sump gasket failure, but the dye revealed a completely different story. Once circulated, the fluorescent trail showed the oil was actually weeping from a seal much higher up the block and simply trailing down the casting.
