## 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.

### ⭐⭐⭐⭐⭐ Easy and definitely works
*by P***G on January 17, 2026*

### ⭐⭐⭐⭐⭐ Work’s well
*by S***T on December 11, 2025*

### ⭐⭐⭐⭐⭐ Great product for diagnosis
*by I***Z on December 8, 2025*

I used this dye to help diagnose a fuel leak in a carburetor. It worked outstandingly well. With just a drop of it in a few ounces of fuel, it lit up bright when exposed to a little UV light. I would not have otherwise been able to find the leak since it was a small weeping leak that did not appear “wet” but the dye showed exactly where it was.
