Review: Useless - Does not identify leak
Review: Works great pinpointed oil leak! Have had a slow oil leak on our 2002 Grand Am for the past 4 years. Nothing serious just an annoying constant oil leak In our driveway. Was leaking about 1 quart between each oil change. At first was convinced it was the pan so changed the oil pan gasket. This did not solve the leak nor did a stop leak product. So purchased this DYE put it in and went for about a 50KM drive. Brought it home, jacked it up and had a look in the dark using a black-light flashlight. Lots of oil around the pan is why I originally thought that was the leak source. Using the black light, the DYE outlined that the leak was coming from a much higher spot and flowng down on to the pan giving the illusion that the oil pan was at fault when in fact it was not. Got my answer and found the leak source

## 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.
